Microbiome Signatures

Overview

Endometriosis affects about 10-15% of women globally, causing chronic pelvic pain, infertility, and other severe symptoms. [1] While experts often point to retrograde menstruation as the cause of endometriosis, this theory falls short because it fails to explain why many women with retrograde menstruation never develop endometriosis, nor does it account for cases in prepubertal girls, postmenopausal women, men, or endometriotic lesions found in locations far from the pelvis, such as the lungs. [2] This clearly indicates that other significant pathophysiological factors are involved.  The lack of a definitive cure and the suboptimal effects of current treatments highlight the urgent need for a breakthrough.

Associated Conditions

While endometriosis primarily affects the endometrium, it can have systemic effects and influence various aspects of a person’s health. Individuals with endometriosis may be at an increased risk for other conditions. These include chronic pelvic pain, infertility, irritable bowel syndrome (IBS), interstitial cystitis, autoimmune conditions, and ovarian cancer. [3][4] Researchers have also documented that many of these comorbidities involve urogenital or gut dysbiosis, suggesting potential microbiome signature overlaps between the conditions. [5]

Causes

Prevailing causal theories of endometriosis—such as retrograde menstruation, Müllerianosis, and lymphovascular metastasis—provide foundational insights but fall short of fully explaining the condition’s complexity. A more comprehensive, systems-based approach that integrates these theories with emerging insights—such as the role of the microbiome and the microbial metallomics theory of endometriosis—offers a more nuanced and integrated understanding of the disease. By challenging entrenched assumptions and embracing granular, data-driven perspectives, we can identify previously overlooked mechanisms driving pathogenesis. This shift not only enriches our understanding of endometriosis but also paves the way for highly personalized treatments that leverage microbiome research, dramatically improving patient outcomes and redefining the standard of care.

What are the current causal theories of endometriosis and their limitations?


TheoryLimitations / Criticisms

Retrograde Menstruation
Theory

While widely accepted, the retrograde menstruation theory does not explain why retrograde menstruation occurs in many women, but only a subset develop endometriosis. It also fails to account for cases in individuals without menstrual cycles, such as prepubertal girls [6], postmenopausal women [7], men [8], and in locations far from the pelvis, such as the lungs. [9]

Environmental Theory

Direct causal links between environmental toxins and endometriosis are difficult to establish, and the environmental theory of endometriosis cannot fully explain hereditary patterns and internal physiological changes associated with the disease. [10]

Coelomic Metaplasia Theory

The coelomic metaplasia theory does not fully explain the occurrence of endometriosis in distant sites, such as the lungs or brain, where the peritoneal lining is not present. [11][12] Endometriotic lesions are heterogeneous in nature, varying in location, morphology, and biological behavior. The coelomic metaplasia theory does not fully account for this heterogeneity, which might be better explained by a multifactorial model involving various pathogenic processes.[13]

Müllerianosis Theory

The Müllerianosis theory struggles to explain isolated occurrences of endometriosis in males or areas unrelated to the embryonic development of the Müllerian ducts, such as the spinal cord [14] or skeletal muscular system [15], suggesting that additional factors must be involved in disease manifestation.

Genetic and Epigenetic Theory

The genetic and epigenetic theory of endometriosis proposes that genetic predisposition and epigenetic modifications significantly influence susceptibility to endometriosis. While genetics play a role, this theory does not account for environmental and acquired aspects of the disease, and specific genetic markers with high predictive value have yet to be identified. [16]

Lymphovascular Metastasis Theory
The lack of consistent evidence for endometrial cell survival and growth in distant systems challenges the lymphovascular metastasis theory, and it does not address the origin of endometriosis in areas not served by the lymphovascular network.
Microbiome TheoryIt is unclear whether dysbiosis is a cause or consequence of endometriosis, and the specific mechanisms by which microbiome alterations contribute to it remain to be fully elucidated. Nonetheless, the microbiome theory of endometriosis is likely to play a significant role in the development of therapies based on recent research findings.
Microbial Metallomics Theory of EndometriosisWhile this model uniquely integrates genetics, environmental factors, the microbiome, and immune function into a cohesive framework with translational potential, the Microbial Metallomics Theory of Endometriosis requires further empirical validation. Additional clinical studies are needed to clarify whether microbial metallomics is a primary driver of endometriosis or a contributing factor to its progression.

Diagnosis

Laparoscopy remains the gold standard for diagnosing endometriosis. Despite its accuracy, laparoscopy is still an invasive procedure with associated risks and costs, necessitating the development of less invasive diagnostic tools. As researchers and clinicians increasingly leverage microbiome signatures and metabolomic signatures for non-invasive diagnostic purposes and treatment guidance, these tools are more likely to become mainstream in medical practice.[17][18] Their growing utility in providing earlier, more accurate diagnoses and tailoring targeted therapies underscores their potential to revolutionize non-invasive diagnostics, particularly in conditions like endometriosis.[19]

Primer

The interplay between metal homeostasis, estrogen metabolism, and metabolomic disruptions in endometriosis reveals how systemic and localized factors converge to drive endometriosis progression. These interrelationships underscore the microbiome’s central role in the disease’s pathogenesis and highlight opportunities for microbiome-based diagnostics and microbiome-targeted interventions (MBTIs).

Nutritional Immunity

Several nutritional immunity factors are found to be elevated in endometriosis. Studies suggest that levels of lactoferrin are significantly increased in individuals with endometriosis, reflecting a heightened immune response. [20] The increased levels of these proteins indicate an attempt by the body to sequester nutrients and metals from pathogens, while also modulating the inflammatory environment associated with endometriosis. This suggests that understanding the role of nutritional immunity could provide insights into the management and treatment of endometriosis.

Metallomic Signature

High iron levels from retrograde menstruation promote pathogenic bacteria, lesion growth, inflammation, and oxidative stress.[21] Studies suggest that nickel sensitivity affects 90.3% of patients, or possibly even more [22], and that a Low-nickel diet (LNiD) shows significant clinical benefits. [23] Zinc, despite its antioxidative and anti-inflammatory role, has been significantly associated with an increased risk of endometriosis owing to the activity of matrix metalloproteinases (MMPs), which are implicated in endometriotic lesion invasion.[24]Metalloestrogens like cadmium, nickel, and lead increase oxidative stress, inflammation, and estrogenic activity. [25] These findings highlight the role that the metallomic signature plays in the condition, and the potential of chelation therapies, dietary modifications, and reduced heavy metal exposures for managing or preventing endometriosis.

What is the metallomic signature of endometriosis?

MetalFindings
IronSystematic reviews confirm that iron levels are abnormally high in endometriosis lesions, where iron chelation therapy has shown efficacy in alleviating symptoms and slowing disease progression.[27] High iron content stems from repeated episodes of retrograde menstruation, during which red blood cells break down, releasing iron into the pelvic cavity. This excess iron disrupts homeostasis, driving inflammation and oxidative stress, which support the growth of endometriotic lesions. Furthermore, pathogenic bacterial species associated with endometriosis exhibit robust iron acquisition mechanisms, indicating that iron dysregulation also influences microbial dynamics in the pelvic environment. [28]
NickelNickel allergy has been identified as a risk factor for endometriosis, and elevated nickel levels in the blood have been suggested as a causal factor in endometriosis development, with 90.3% of women experiencing allergic contact mucositis (ACM). [29][30] Nickel’s classification as a metalloestrogen highlights its estrogen-mimicking capabilities, contributing to hormonal dysregulation in endometriosis. [31] Women with nickel sensitivity frequently report gastrointestinal symptoms overlapping with irritable bowel syndrome (IBS). Positive nickel oral mucosa patch tests (omPT) further validate this connection. [33] Screening for nickel sensitivity in endometriosis patients with gastrointestinal symptoms and recommending a low-nickel diet are key considerations for personalized treatment strategies.
CadmiumCadmium is a metalloestrogen that mimics estrogen by binding to estrogen receptors, potentially contributing to the pathogenesis of endometriosis, an estrogen-dependent disease. [34] Research has linked cadmium exposure to oxidative stress, which plays a significant role in the development of endometriosis. By inducing the formation of reactive oxygen species (ROS) and impairing antioxidant defenses, cadmium exacerbates oxidative damage to cellular components, including DNA and proteins. However, findings regarding cadmium’s direct association with endometriosis remain inconsistent. While some studies report elevated cadmium levels in women with endometriosis, others find no significant difference. A systematic review has highlighted the need for more robust investigations to determine cadmium’s precise role. The potential synergistic effects of cadmium with other heavy metals, such as lead, may amplify its impact on oxidative stress and disease progression. [35][36]
LeadLead exposure is also implicated in the pathogenesis of endometriosis through its oxidative and endocrine-disrupting effects. Studies have shown a significant association between blood lead levels (BLLs) and the prevalence of endometriosis, with even low levels (<5 µg dl) contributing to increased risk. furthermore, lead exposure appears have a synergistic effect when combined with cadmium, amplifying oxidative stress and potentially accelerating disease progression. occupational particularly in industrial settings, has been associated hospitalization rates for endometriosis.  [37][38][39]
ZincHigher dietary zinc intake has been significantly associated with an increased risk of endometriosis, with women consuming over 14 mg/day showing a 60% greater likelihood of the condition compared to those consuming ≤8 mg/day (adjusted odds ratio: 1.60, 95% CI: 1.12–2.27, p = 0.009). Zinc, despite its antioxidative and anti-inflammatory roles, may have a counterproductive effect when consumed in excess, potentially influencing immune modulation, oxidative stress, and the activity of matrix metalloproteinases (MMP-2 and MMP-9), which are implicated in endometriotic lesion invasion. [40]



Estrogen Metabolism 

The estrobolome, a subset of gut microbiome genes, regulates estrogen metabolism and plays a critical role in endometriosis progression. Major microbial associations (MMAs) in the endometriosis microbiome signature, such as Escherichia coli, Bacteroides fragilis, and Streptococcus agalactiae produce β-glucuronidase, increasing estrogen deconjugation and circulating hormone levels. This microbial activity drives inflammation, angiogenesis, hormonal dysregulation, and cellular changes, contributing to endometriosis pathogenesis. Dysbiosis in endometriosis is both a cause and consequence of the disease. [41][42][43]

Microbiome Signature: Endometriosis

Interventions

Our validation method confirms microbiome-targeted interventions (MBTIs) by aligning therapeutic effects on microbial imbalances with clinical outcomes, key pathological markers, and major microbial associations (MMAs) of endometriosis. This dual approach ensures that interventions address both dysbiosis and the condition’s core biological mechanisms, reinforcing the accuracy of microbiome signatures and the efficacy of MBTIs. Promising candidates with partial alignment or preliminary benefits are also identified for further research, ensuring a pipeline of innovative therapies for future validation.

Validation In Progress

Axitinib, Afatinib, LinifanibDrug RepurposingDrugs like Axitinib, Afatinib, and Linifanib, known for their anti-angiogenic effects inhibit the growth of blood vessels that sustain ectopic endometrial tissue. By reducing angiogenesis, these drugs, or similar VEGFR / PDGFR / EGFR/ HER2 inhibitors may help reduce symptoms of endometriosis. [31]
3D printed pirfenidone ovulesDrug RepurposingPirfenidone, used against idiopathic pulmonary fibrosis, shows promise in endometriosis treatment due to its anti-fibrotic properties. Studies are exploring 3D-printed vaginal ovules for its delivery. These ovules offer controlled release, higher efficacy, and fewer side effects. [32]
Transvaginal Photobiomodulation Biophysical InterventionTransvaginal photobiomodulation reduced inflammation and improved pain in endometriosis study participants. [33]
Vaginal Microbiome Transplant (VMT)Microbiome Restoration An animal model study investigating the efficacy of antibiotics and VMT for endometriosis found that both modalities were effective, and reduced disease progression via the NF-κB Signaling Pathway. [34]
Fecal Transplant (FMT)Microbiome Restoration As of now, there are no clinical trials or peer-reviewed studies specifically evaluating FMT as a treatment for endometriosis. Nonetheless, several reviews have speculated that it would be an effective treatment option based on the emerging understanding of the gut microbiome’s role in the condition. [35, 36, 37, 38]
Low Trans-unsaturated fatty acids and red meat dietDietTrans-unsaturated fatty acids and red meat are associated with an increased risk of developing endometriosis. [40]
Fruits, vegetables, dairy products, and omega-3 fatty acidsDietWomen who consume a large amount of fruits, vegetables, dairy products, and omega-3 fatty acids have an attenuated risk of endometriosis. [41]
Omega-3 polyunsaturated fatty acidsDietFound to attenuate inflammation in endometriosis models [42]; high intake correlated with a lower risk of endometriosis development. [43]
Mediterranean DietDietA study found that Mediterranean Diet adherence impacts the endometrial environment, suggesting diet modifications could enhance fertility. [45]
Increased Fruit intake, particularly citrus, decreased vegetable intake, particularly cruciferous vegetables. Diet Higher fruit intake, especially citrus fruits, was inversely associated with laparoscopically confirmed endometriosis, suggesting a protective effect potentially linked to beta-cryptoxanthin. In contrast, cruciferous vegetables were linked to increased risk, highlighting the complex interplay between diet and endometriosis risk factors. [54]

Hexane extract of Aged Black GarlicSupplementThe research on aged black garlic, specifically its hexane extract (HEABG), shows significant promise for endometriosis treatment. HEABG inhibits cell proliferation and cell cycle progression in TNF-α-activated human endometriotic stromal cells. This action occurs through the suppression of the ERK and JNK signaling pathways [50]. Additionally, HEABG reduces TNF-α-induced expression of ICAM-1 and VCAM-1 by inhibiting NF-κB and AP-1[51]. These mechanisms could decrease immune cell recruitment to lesions, potentially reducing disease-related inflammation. These findings position aged black garlic, particularly its hexane extract, as a promising candidate for further research in endometriosis treatment. The antioxidant, anti-cancer, and pro-apoptotic properties of aged black garlic extracts have been noted in various studies, contributing to a growing body of evidence supporting its therapeutic potential in a range of pathologies [52].
ResveratrolSupplementThe potential therapeutic effects and molecular mechanisms of resveratrol on endometriosis are primarily due to its anti-inflammatory, anti-proliferative, anti-angiogenic, and antioxidative properties [53].

Several studies have demonstrated that resveratrol can inhibit the growth and angiogenesis (formation of new blood vessels) of endometrial tissue, which is a key factor in the development of endometriosis. It has been observed that resveratrol supplementation in animal models of endometriosis resulted in a decrease in the number and volume of endometrial implants, as well as a suppression of proliferation, vascularization, and inflammation in these implants. [54]

Furthermore, resveratrol has been shown to increase apoptosis (programmed cell death) in endometriotic cells and reduce their invasiveness. This suggests that resveratrol could potentially alter the cellular mechanisms that drive the progression of endometriosis. [55].
Catechins (green tea)SupplementCatechins, particularly epigallocatechin-3-gallate (EGCG) from green tea, show beneficial effects for endometriosis. EGCG inhibits angiogenesis, crucial for endometriosis growth. It has been found to reduce lesion size and angiogenesis in experimental models. EGCG also induces apoptosis and modulates inflammatory responses in lesions [x, x] .
CurcuminSupplementCurcumin, from turmeric, exhibits potential in endometriosis treatment through its multi-targeted actions. It inhibits the growth of endometriosis cells and decreases VEGF expression, affecting cell survival pathways. Curcumin’s broad spectrum of anti-inflammatory and anti-angiogenic properties makes it a candidate for further research in endometriosis management [x].
Uncaria tomentosaSupplementUncaria tomentosa shows promise due to its anti-inflammatory and anti-angiogenic properties. In animal studies, Uncaria tomentosa extract reduced endometriotic lesion size [x].
Açai extract
(Euterpe oleracea)
SupplementAçai extract is renowned for its strong antioxidant, anti-inflammatory, and anticancer properties. These benefits largely stem from its rich polyphenol content, especially anthocyanins. Research supports Açai extract’s effectiveness in both in vivo and in vitro settings, as it suppresses the growth and survival of endometriotic lesions and reduces their size. This suggests a new strategy for managing endometriosis by targeting key pro-inflammatory and pro-angiogenic markers and influencing macrophage viability [x.
European cranberry bush
(Viburnum opulus)
SupplementResearch shows that Viburnum opulus extract decreases the size of endometriotic lesions. It achieves this by lowering TNF-α, VEGF, and IL-6 levels. Thus, Viburnum opulus may disrupt inflammatory and angiogenic pathways involved in endometriosis development and progression. The reduction in these biomarkers indicates that Viburnum opulus could regulate the inflammatory environment associated with endometriosis. This regulation might reduce lesion size and ease symptoms. Studies highlight that fruit extracts of V. opulus, especially EtOAc and MeOH extracts, show significant therapeutic potential in treating endometriosis. The presence of chlorogenic acid and other phenolic compounds may enhance this potential. This research supports the traditional use of V. opulus in treating gynecological conditions [x].
Milk thistle (Silybum marianum)SupplementSilymarin significantly inhibits the establishment and growth of endometriotic lesions. It mediates its effects by downregulating crucial factors such as GDNF, its receptor gfrα1, Bcl-6b, and Bcl-2. These factors are involved in cell survival, proliferation, and neurotrophic support. Thus, silymarin may inhibit lesion growth by promoting apoptosis and inhibiting proliferation. Additionally, an increase in ERK1/2 expression indicates silymarin’s role in activating apoptotic pathways. Silymarin treatment also results in decreased angiogenesis and increased fibrosis. This suggests it may limit lesion nourishment and promote lesion regression. Therefore, silymarin offers a potentially comprehensive approach to managing endometriosis by affecting several key pathological processes [x].
Calligonum comosumSupplementIn both in vitro and in vivo studies, Calligonum comosum reduces the size of endometriotic lesions. It accomplishes this through its anti-inflammatory and anti-proliferative properties. The plant decreases vascularization by inhibiting angiogenesis, reducing the nutrient supply to lesions and alleviating pain. Moreover, it curbs the proliferation of endometrial cells by targeting cell growth pathways, thus reducing hyperplasia in lesions. Additionally, it lessens immune cell infiltration in lesions, easing inflammation and discomfort. These findings highlight its potential in reducing endometriotic lesion size, vascularization, cell proliferation, and immune cell infiltration [x].
Frankincense (Boswellia serrata)SupplementFrankincense alleviates endometriosis by inducing apoptosis and reducing cell adhesion [x]. Its oils exhibit synergistic, additive, and non-interactive properties against various microorganisms. Specifically, Cryptococcus neoformans and Pseudomonas aeruginosa show high susceptibility to these oils [x].
MelatoninSupplementEvidence shows that exogenous melatonin can suppress ectopic lesions, alleviate pelvic pain, and improve sleep quality in women with endometriosis, underscoring its multifaceted role in managing both the symptoms and underlying aspects of the condition [x]. Other studies found that melatonin could prevent and treat endometriosis by reducing the size and weight of the endometriotic lesions [x]. Melatonin has also been shown to reduce the Firmicutes/Bacteroidetes ratio [x], which is increased in endometriosis patients relative to healthy controls [x].
Vitamin DSupplementMalondialdehyde level is commonly known as a marker of oxidative stress and antioxidant status [x]. Studies have found a higher level of MDA in the serum of women with endometriosis relative to healthy controls [x].  Systematic reviews have confirmed that Vitamin D supplementation significantly reduces MDA [X]  Some studies have found that vitamin D supplementation significantly decreased pelvic pain and c-reactive protein scores [x], while other studies found that vitamin D treatment did not have a significant effect in reducing dysmenorrhea and/or pelvic pain [x].
NAC (N-Acetylcysteine) SupplementOral supplementation with NAC improves endometriosis-related pain and appears to improve fertility in patients with endometriosis.[x]
ProbioticsSupplementProbiotics and prebiotics have shown potential in optimizing, maintaining, and restoring vaginal microflora, offering alternative approaches to reduce vaginal infections and promote overall female health. [x]
PrebioticsSupplementResearch suggests that abnormal gut microbiota impacts female reproductive system diseases, particularly through dysbiosis-induced hypoestrogenemia, using endometriosis and its potential malignancy progression linked to genetic mutations as examples. It suggests that modifying gut microbiota with prebiotics and probiotics could help prevent and treat hormone-related gynecological diseases. [x]
QuercetinSupplementQuercetin, a flavonol, may help manage the disease by modulating estrogen activity, reducing inflammation, suppressing angiogenesis, and promoting apoptosis in endometrial cells. [x]
Indole-3-carbinolSupplementIndole-3-Carbinol significantly inhibits both the growth and vascularization of endometriotic lesions without causing adverse effects on reproductive organs. Specifically, I3C reduced the number of proliferating stromal and endothelial cells within the lesions and downregulated the expression of key pro-angiogenic molecules such as vascular endothelial growth factor receptor-2 (VEGFR2), phosphoinositide 3-kinase (PI3K), and phosphorylated extracellular signal-regulated kinase (pERK). These results suggest that I3C may interfere with angiogenic and proliferative pathways essential for the development of endometriotic lesions. [x]
deferoxamine, deferiprone, and deferasiroxPharmaceuticalStudies have found that there is excess iron in the peritoneal cavity due to recurrent bleeding from endometrial lesions [x]. This excess iron provides pathogens with the necessary ions for biofilm formation and virulence factors, while other studies have found that excess iron has a deleterious effect on Lactobacillus spp [x]. Microbial iron chelators are being explored as a novel approach to developing innovative antimicrobials, with siderophore-mimicking antibiotics emerging as a targeted strategy against pathogens. These compounds have shown effectiveness against antibiotic-resistant Gram-negative bacteria, highlighting their potential in combating tough microbial challenges. Beyond their antimicrobial applications, iron chelators are also being studied for their utility in treating iron overload diseases and as potent agents in cancer therapy. This multifaceted use of iron chelators underscores their significant potential across various medical fields, including endometriosis [x]. Further, in vivo experiments show that the iron chelator deferoxamine reduced the implant size in experimental endometriosis [x].
LactoferrinSupplementResearch on prebiotics that specifically improve the population of Lactobacillus in the female reproductive tract is limited. However, a study highlighted in the PubMed article “Antimicrobial and Prebiotic Activity of Lactoferrin in the Female Reproductive Tract: A Comprehensive Review” suggests that lactoferrin, a protein found in milk and other secretions, may have prebiotic activities.Lactoferrin can potentially support the growth of beneficial bacteria like Lactobacillus in the female reproductive tract, contributing to its health. This indicates that lactoferrin might play a role in maintaining a healthy balance of microbiota in the genital tract, and could prove useful in the treatment of endometriosis [x]
GalliumBiochemical ChelationGallium as an iron mimic, disrupting bacterial iron metabolism when taken up instead of iron [x]. Effective in reducing bacterial load and inflammation. Shown to reduce P. aeruginosa lung infections in cystic fibrosis models in vivo.

Gallium, a trivalent metal, functions as an iron mimic, disrupting bacterial iron metabolism when incorporated in place of iron. This disruption impairs essential processes such as DNA synthesis and respiration, leading to bacterial growth inhibition and cell death. Studies have demonstrated gallium’s efficacy in reducing bacterial load and inflammation, particularly against Pseudomonas aeruginosa, a common pathogen in cystic fibrosis (CF) lung infections. In vivo experiments have shown that gallium can inhibit P. aeruginosa growth and biofilm formation, making it a promising candidate for treating chronic lung infections in CF patients. [x]


Additionally, gallium has been evaluated in clinical settings. A phase I clinical trial involving individuals with CF and chronic P. aeruginosa airway infections indicated that gallium administration was safe and achieved concentrations sufficient to inhibit bacterial growth.
AAAS

These findings suggest that gallium-based therapies could offer a novel approach to managing persistent bacterial infections, especially in cases where traditional antibiotics are ineffective due to resistance or biofilm formation.
Local pH Modification with lactic acid suppositoriesEnvironmental ModificationWhile the importance of breathable fabrics like cotton for maintaining vaginal health is often highlighted in health advice and articles, there is a gap in clinical research directly linking the type of underwear fabric to specific reproductive health outcomes. This suggests an area for future research to provide more evidence-based guidance. Nonetheless, there is interaction between different types of bacteria and various fabric materials. Studies have shown that bacteria implicated in the etiology of endometriosis, specifically Staphylococcus aureus and Staphylococcus epidermidis, demonstrated increased adherence to fabrics as the content of polyester fibers in the fabrics increased [x]. Understanding these dynamics is crucial, particularly in relation to female reproductive health and infection control. The findings highlight that the material composition of fabrics can influence bacterial adherence, which could have implications for infection prevention strategies.
Oral Sex Behavioral-Physiological ModulationResearch suggests that women who reported engaging in oral sex were less likely to have endometritis, a condition associated with Pelvic Inflammatory Disease (PID). Although endometritis is distinctly different from endometriosis, the study proposes that oral sex could stimulate an effective immune response in the genital tract, possibly due to antigenic priming of the lymphatic system, which is abundant in the oropharynx. This hypothesis, however, requires further investigation for validation [x].
Sexual activity, orgasm, and tampon use during menstruationBehavioral-Physiological ModulationSexual activity, orgasm, and tampon use during menstruation protect against endometriosis. [x]
Cotton undergarments Behavioral-Physiological ModulationWhile the importance of breathable fabrics like cotton for maintaining vaginal health is often highlighted in health advice and articles, there is a gap in clinical research directly linking the type of underwear fabric to specific reproductive health outcomes. This suggests an area for future research to provide more evidence-based guidance. Nonetheless, there is interaction between different types of bacteria and various fabric materials. Studies have shown that bacteria implicated in the etiology of endometriosis, specifically Staphylococcus aureus and Staphylococcus epidermidis, demonstrated increased adherence to fabrics as the content of polyester fibers in the fabrics increased [x]. Understanding these dynamics is crucial, particularly in relation to female reproductive health and infection control. The findings highlight that the material composition of fabrics can influence bacterial adherence, which could have implications for infection prevention strategies.
Dimethylglyoxime (DMG)Biochemical ChelationGiven that nickel can have estrogenic effects and considering the high prevalence of nickel sensitivity in individuals with endometriosis, as suggested by studies indicating the improvement of symptoms following a low-nickel diet, DMG could theoretically mitigate some of the estrogen-mediated processes in endometriosis by chelating nickel. This would be particularly relevant if nickel is contributing to the disease’s severity or symptomatology through its estrogenic properties.While specific studies in the context of endometriosis are lacking, research on DMG’s bacteriostatic action in other contexts can provide a theoretical basis [x]. 
ZeoliteBiochemical ChelationClinoptilolite zeolite, known for its ability to chelate several heavy metals such as nickel, has shown promising benefits for reproductive health, particularly in animal studies. By binding to nickel, zeolite can inhibit the activity of pathogens that rely on this metal as a cofactor for enzymes crucial to their survival, biofilm formation, and virulence, thereby reducing inflammation and promoting a healthier microbial balance. Beyond its antimicrobial effects, zeolite acts as a detoxifying agent, antioxidant, and immunostimulant, which helps manage oxidative stress and enhance energy levels during the postpartum period. These combined effects support the recovery of the reproductive system after birth, creating a more favorable environment for subsequent fertility and demonstrating its potential as a microbiome-targeted intervention. [x]
D-Chiro InositolSupplementD-Chiro Inositol’s ability to reduce the development of endometriotic lesions in a mouse model suggests a therapeutic potential for this compound in the treatment of endometriosis. This finding is noteworthy because it opens a new avenue for non-hormonal treatment options, which can be particularly beneficial for patients who are unable to use hormonal therapies due to side effects or other contraindications [x].
Phage Cocktail TherapyMicrobiome RestorationPhage cocktails, compared to monophage therapy, are often employed to treat individual and multi-bacterial infections due to their enhanced efficacy in preventing bacterial resistance. When multiple phages are used simultaneously, as in a cocktail, the diverse mechanisms of action and target specificities reduce the likelihood that bacteria will develop resistance. This approach capitalizes on the various ways different phages attack bacteria, making it more challenging for bacterial populations to adapt and survive. Consequently, phage cocktails can be a more robust strategy against bacterial infections, particularly in scenarios where resistance to conventional antibiotics is a concern [x] Phage cocktails that target the specific microbiome signature of endometriosis would present major benefits for more advanced stages of endometriosis.
Ceylon Cinnamon Oil SupplementWhile Ceylon cinnamon may be used in traditional or alternative treatments for endometriosis, its effectiveness has not been confirmed in clinical trials​. Nonetheless, Ceylon cinnamon oil does have activity against pathogens consistent with the Microbiome Signature of Endometriosis. Cinnamomum zeylanicum (CZ-EO) essential oil showed moderate activity against Fusobacterium nucleatum and Streptococcus mutans. The minimum inhibitory concentrations (MICs) and minimum bactericidal concentrations (MBCs) for Fusobacterium nucleatum were both found to be 125 μg/mL, while for Streptococcus mutans, the MIC was 200 μg/mL and the MBC was 400 μg/mL [x] .
Asparagus racemosusSupplementAsparagus racemosus
Asparagus racemosus has demonstrated considerable antibacterial efficacy against various pathogenic bacteria. In a study, different concentrations of the methanol extract of Asparagus racemosus roots were tested and found to be effective against a range of bacteria implicated in the pathogenesis of endometriosis, including Escherichia coli, Shigella dysenteriae, Shigella sonnei, Shigella flexneri, Vibrio cholerae, Salmonella typhi, Salmonella typhimurium, Pseudomonas putida, Bacillus subtilis, and Staphylococcus aureus. [x] .
Trichostatin A Drug Repurposing Trichostatin A is a hydroxamic acid produced by S. hygroscopicus. Wu et al. published three studies showing that trichostatin A (TSA) reduces invasiveness and reactivates E-cadherin in endometriotic cell lines, upregulates PPARγ expression, and inhibits NF-κB activation. Seo et al. found that TSA induces apoptosis and NSAID-activated gene-1 expression in endometriotic stromal cells. Lu et al. demonstrated that TSA reduced lesion size, improved pain response, and lowered neural marker expression in a rat model. Collectively, TSA shows promise as a histone deacetylase inhibitor (HDACI) for endometriosis treatment.[61]

Trichostatin A chelates zinc ions in the active site of histone deacetylases, preventing histone unpacking so DNA is less available for transcription. TSA remains one of the most potent HDAC inhibitors available. [62]

STOPs

A STOP (Suggested Termination Of Practice) recommends discontinuing medical interventions shown to be ineffective, harmful, or counterproductive based on emerging evidence. In endometriosis, heavy menstrual bleeding often leads to iron-deficiency anemia, traditionally treated with iron supplementation. However, iron supports bacteria linked to endometriosis, and iron supplementation is associated with increasing adverse effects. [x] Paradoxically, iron chelation therapies may improve absorption while reducing inflammation, highlighting the need to re-evaluate traditional practices. This illustrates how STOPs advance evidence-based care by addressing outdated or counterproductive treatments.

What STOPs should be further considered?
STOPsSWAPs
Iron Supplementation: Meta-analyses confirm that iron supplementation with ferrous sulfate is associated with a significant increase in gastrointestinal-specific side effects [x]. Iron deposits found in endometriotic lesions promote further lesion development, suggesting that iron supplementation could aggravate the disease. We are not alone in sounding the alarm on iron supplementation practices, as hypotheses from other studies suggest that iron supplementation could potentially exacerbate infection risks.[x]

The mechanistic role of iron acquisition by pathogens involved in endometriosis challenges current iron supplementation practices.
Lactoferrin
Zinc Supplementation: Higher dietary zinc intake has been significantly associated with an increased risk of endometriosis, with women consuming over 14 mg/day showing a 60% greater likelihood of the condition compared to those consuming ≤8 mg/day (adjusted odds ratio: 1.60, 95% CI: 1.12–2.27, p = 0.009). Zinc, despite its antioxidative and anti-inflammatory roles, may have a counterproductive effect when consumed in excess, potentially influencing immune modulation, oxidative stress, and the activity of matrix metalloproteinases (MMP-2 and MMP-9), which are implicated in endometriotic lesion invasion. [63][x] These findings underscore the need for cautious zinc supplementation and further research to confirm causality and refine dietary recommendations.
Gonadotropin-releasing hormone agonist (GnRHa): Because GnRHa causes anovulation and amenorrhea, GnRHa are used to treat endometriosis [x].

However, a case-controlled molecular study on 32 women, half with endometriosis and half without, investigated microbial colonization in the intrauterine environment and ovarian cystic fluid. 16S metagenome assay indicated that the proportion of Lactobacillacae was significantly decreased (p<0.01) and of Streptococcaceae, Staphylococaceae, and Enterobacteriaceae was significantly increased (p<0.05 for each) in GnRHa-treated women with endometriosis than in GnRHa-untreated women. The study suggests GnRHa treatment might actually promote sub-clinical infections in the intrauterine and ovarian environments. [x]

Other studies investigating the long-term effects of GnRHa with and without hormone replacement therapy on bone mineral density in women with endometriosis found that long-term use of GnRH agonists results in a reduction in bone mineral density at the lumbar spine and hip. This reduction was not fully recovered even up to six years post-treatment. The study also found that the inclusion of hormone replacement therapy (HRT) did not significantly influence bone mineral density when compared to those who did not receive HRT. The results also demonstrated a considerable range of individual variability in BMD response among the participants, suggesting that the effects of GnRH agonists on BMD can vary significantly among different women.
Hormone Replacement Therapy [x]
Cruciferous Vegetables: The consumption of cruciferous vegetables is associated with an increased risk of endometriosis. [64]Citrus Fruit

FAQs

Should we be targeting the gut flora instead of the vaginal microbiota for treatment? 

We should probably be targeting both, even though recent studies found that vaginal microbiota may not be as important as the gut microbiota for the predictive value in endometriosis. u003csupu003e[u003ca href=u0022https://doi.org/10.3389/fcimb.2021.788836u0022u003exu003c/au003e]u003c/supu003e However, looking at the microbiome signature of IBD for more gut-specific microbiome targets will likely result in better treatment strategies since it is commonly associated with endometriosis.rnrnConsider that u003ca href=u0022https://microbiomesignatures.com/definition/estrogen/u0022u003eestrogenu003c/au003e appears to mediate the microbiome as much as the microbiome mediates estrogen. u003csupu003e[u003ca href=u0022https://doi.org/10.1093/biolre/ioac147u0022u003exu003c/au003e]u003c/supu003e

Can a low-nickel diet alone significantly alter the microbiome, or are additional interventions necessary?

Diet is a key modulator of the microbiome, with different dietary patterns influencing microbial composition and function. While a u003ca href=u0022https://microbiomesignatures.com/interventions/low-nickel-diet/u0022u003elow-nickel dietu003c/au003e alone can have a substantial impact, additional interventions such as probiotics, prebiotics, u003ca href=u0022https://microbiomesignatures.com/definition/vaginal-microbiome-transplant-vmt/u0022u003eVMTu003c/au003e and u003ca href=u0022https://microbiomesignatures.com/definition/fecal-microbiota-transplantation-fmt/u0022u003eFMTu003c/au003e may be necessary to achieve specific therapeutic outcomes, especially in cases of severe dysbiosis or comorbid conditions, such as IBD.

Are microbiome-targeted interventions a suitable alternative for patients concerned about fertility while managing endometriosis?

Yes, microbiome-targeted interventions could be a promising alternative for patients concerned about fertility, as they do not rely on hormonal suppression, which can affect ovulation and fertility. By focusing on modulating the microbiome to reduce inflammation and pain, MBTIs may help manage endometriosis symptoms while preserving reproductive potential, making them an attractive option for those planning pregnancy or seeking non-hormonal management strategies.

How do personalized microbiome therapies differ from conventional treatments?

Personalized microbiome therapies are tailored to an individual’s unique microbiome profile, taking into account their specific microbial composition, genetics, diet, and lifestyle. This approach contrasts with conventional treatments, which often take a one-size-fits-all approach. Personalized therapies aim for higher efficacy and fewer side effects by targeting the unique microbiome-related needs of each patient.

How can we assess the effectiveness of a microbiome-targeted intervention in a patient?

Effectiveness can be assessed through various methods, including monitoring clinical outcomes, changes in microbiome composition through sequencing technologies, biomarkers of inflammation or disease, and patient-reported outcomes. Regular follow-ups and adjustments to the intervention may be necessary based on these assessments to optimize therapeutic benefits.

What advancements are needed to integrate microbiome signatures into routine clinical practice?

To integrate microbiome signatures into routine clinical practice, advancements in standardized methodologies for microbiome sampling, data analysis, and interpretation are needed. Additionally, more large-scale, longitudinal studies are required to establish robust, clinically relevant microbiome biomarkers and validate them across diverse populations and conditions.

Escherichia coli (E. coli) is a versatile bacterium, from gut commensal to pathogen, linked to chronic conditions like endometriosis.

Streptococcus spp.

Streptococcus is a genus of gram-positive, facultatively anaerobic bacteria commonly found in pairs or chains. Important human pathogens include Streptococcus pneumoniae, Streptococcus pyogenes (group A strep), and Streptococcus agalactiae (group B strep).

β-Glucuronidase

β-glucuronidase in the gut microbiome breaks down metabolites, drugs, and hormone conjugates like estrogen, aiding microbial energy use and nutrient cycling. Its activity influences drug efficacy and hormone levels, maintaining estrogen balance and impacting health. Disruption in this process can lead to estrogen-related diseases, such as gynecological cancers and menopausal syndrome, and increase colorectal cancer risks by reactivating carcinogens, highlighting its pivotal role in linking microbial actions to host physiological processes.

Microbiome-Targeted Interventions (MBTIs)

Microbiome Targeted Interventions (MBTIs) are cutting-edge treatments that utilize information from Microbiome Signatures to modulate the microbiome, revolutionizing medicine with unparalleled precision and impact.

Pueraria Flower Extract (PFE)

Pueraria lobata (kudzu) is used in traditional medicine for cardiovascular issues, menopause, and alcohol dependence due to its bioactive isoflavones. These compounds, particularly puerarin, offer vasodilatory effects and antioxidant properties, enhancing blood circulation and reducing oxidative stress.

Validation of Pueraria Flower Extract (PFE) as a Microbiome-targeted intervention for Endometriosis

Pueraria Flower Extract (PFE) addresses microbial imbalances and inflammation in endometriosis, validating its role as a microbiome-targeted therapy.

Validation of Metronidazole as a microbiome-targeted intervention for Endometriosis

Metronidazole is a validated microbiome-targeted intervention (MBTI) for endometriosis, reducing key dysbiotic taxa and suppressing inflammation and lesion progression.

Metformin

Metformin is a synthetic derivative of guanidine derived from the guanidine alkaloid of the plant Galega officinalis L. with significant hypoglycemic effects. It is a first-line antihyperglycemic agent due to its efficacy, low cost, and favorable safety profile.

Validation of Metformin as a Microbiome-targeted intervention for Endometriosis

By directly targeting microbial dysbiosis, hormonal imbalances, and inflammation, metformin not only validates the clinical relevance of the endometriosis microbiome signature but also positions itself as an effective therapeutic option for the condition.

Low‑Nickel Diet (LNiD)

A low-nickel diet (LNiD) is a therapeutic dietary intervention that eliminates high-nickel foods, primarily plant-based sources such as legumes, nuts, whole grains, and cocoa, to reduce systemic nickel exposure. It is clinically validated for managing systemic nickel allergy syndrome (SNAS) and nickel-induced eczema. Its relevance is well-established in microbiome modulation, with studies demonstrating clinical benefits in conditions such as endometriosis, fibromyalgia, irritable bowel syndrome, and GERD.

Validation of a Low-Nickel Diet as an microbiome-targeted intervention for Endometriosis

A low-nickel diet is validated as an MBTI for endometriosis because it disrupts nickel-dependent pathogens, rebalances the microbiome, and improves symptoms like pelvic pain and dysmenorrhea.

Hyperbaric Oxygen Therapy (HBOT)

Hyperbaric Oxygen Therapy (HBOT) involves breathing pure oxygen in a pressurized chamber, which increases the amount of oxygen dissolved in the blood and delivered to tissues.

Hyperbaric Oxygen Therapy (HBOT) as a Promising Candidate in Endometriosis treatment

HBOT demonstrates complete remission and holds significant promise as a candidate for microbiome-targeted intervention for endometriosis.

Lactoferrin

Lactoferrin (LF) is a naturally occurring iron-binding glycoprotein classified as a postbiotic with immunomodulatory, antimicrobial, and prebiotic-like properties.

Transvaginal Photobiomodulation

Transvaginal photobiomodulation (TVPBM) is an emerging therapeutic modality that uses light therapy to address various gynecological and pelvic health issues. This treatment is noninvasive and uses specific wavelengths of light to stimulate cellular functions, promoting healing and reducing inflammation.

Vaginal Microbiome Transplant (VMT)

Vaginal Microbiome Transplant (VMT) involves transferring healthy vaginal flora from a donor to a recipient to treat conditions like recurrent bacterial vaginosis. It aims to restore balance in the vaginal microbiome, potentially offering a non-pharmacological treatment option for persistent gynecological disorders.

Fecal Microbiota Transplantation (FMT)

Fecal Microbiota Transplantation (FMT) involves transferring fecal bacteria from a healthy donor to a patient to restore microbiome balance.

Flavones and Flavonols

Flavones and flavonols are plant-derived compounds known for their antioxidant, anti-inflammatory, and antimicrobial properties.

Lactoferrin

Lactoferrin (LF) is a naturally occurring iron-binding glycoprotein classified as a postbiotic with immunomodulatory, antimicrobial, and prebiotic-like properties.

Gallium

Gallium is studied for its unique antimicrobial and anticancer properties. It inhibits metalloproteinases, disrupts bacterial iron metabolism, and may enhance antibiotic efficacy, particularly against resistant strains. Gallium compounds show potential as non-traditional therapeutic agents in treating infections and inhibiting cancer cell invasion and metastasis.

Gallium compounds show potential as non-traditional therapeutic agents in treating infections and inhibiting cancer cell invasion and metastasis.

Clinoptilolite Zeolite

Clinoptilolite zeolite binds nickel ions, reducing pathogen activity, making it a potential therapy for nickel allergies and nickel-induced microbiome imbalances.

STOPs

A STOP (Suggested Termination Of Practices) is a recommendation that advocates for the discontinuation of certain medical interventions, treatments, or practices based on emerging evidence indicating that these may be ineffective, harmful, or counterproductive in the management of specific conditions.

Lactoferrin

Lactoferrin (LF) is a naturally occurring iron-binding glycoprotein classified as a postbiotic with immunomodulatory, antimicrobial, and prebiotic-like properties.

Zinc

Zinc is an essential trace element vital for cellular functions and microbiome health. It influences immune regulation, pathogen virulence, and disease progression in conditions like IBS and breast cancer. Pathogens exploit zinc for survival, while therapeutic zinc chelation can suppress virulence, rebalance the microbiome, and offer potential treatments for inflammatory and degenerative diseases.

Matrix Metalloproteinases (MMPs)

Matrix Metalloproteinases (MMPs) are zinc-dependent enzymes that regulate extracellular matrix remodeling, with critical roles in health, disease, and interactions with the microbiome.
