Quick Summary
This study looked at whether gynecological history—including conditions like endometriosis, pelvic pain, and surgeries—might be connected to ME/CFS. Researchers compared 36 women with ME/CFS to 48 healthy women and found that women with ME/CFS reported more pelvic pain, endometriosis, and gynecological surgeries. The study suggests that gynecological health may play a role in ME/CFS and deserves closer medical attention.
Why It Matters
This study provides evidence that gynecological conditions and surgeries occur more frequently in women with ME/CFS, suggesting that reproductive and hormonal factors may be relevant to disease pathophysiology. Understanding these associations could improve clinical evaluation and care for the majority of ME/CFS patients who are women, and may inform future research into hormonal mechanisms in the disease.
Observed Findings
Women with CFS reported pelvic pain unrelated to menstruation more frequently (22.2% vs 1.7%, p=0.004)
Endometriosis was more prevalent in the CFS group (36.1% vs 16.7%, p=0.046)
Women with CFS had a higher mean number of pregnancies (2.8 vs 2.0, p=0.05)
Women with CFS underwent more gynecological surgeries on average (1.8 vs 1.1, p=0.05)
Menopause occurred approximately 4.4 years earlier in the CFS group (41.7 vs 46.1 years)
Inferred Conclusions
Gynecological conditions and surgical procedures are more common in women with CFS than in matched controls
Gynecological health assessment should be a standard part of clinical evaluation for women with CFS
Future research is needed to clarify whether and how gynecological conditions contribute to ME/CFS pathophysiology
Hormonal and reproductive factors may play a relevant role in ME/CFS disease mechanisms
Remaining Questions
Is the temporal relationship causal (do gynecological conditions trigger ME/CFS, or does ME/CFS predispose to these conditions)?
What are the biological mechanisms linking gynecological conditions and ME/CFS?
What This Study Does Not Prove
This study does not establish that gynecological conditions cause ME/CFS or vice versa—only that they co-occur more frequently. The study cannot determine the chronological relationship (which came first) or the biological mechanisms linking these conditions. Additionally, the modest sample size and some findings approaching but not reaching statistical significance limit the generalizability of results.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
