Strategic Insights

— 1 min read

A systematic review conducted at the Royal Hospital for Women in Sydney, Australia, has shed light on the prevalence of endometriosis in the trans male population. The study, published in the Journal of Minimally Invasive Gynecology, found that 8.9% of trans men studied had endometriosis, with a significant proportion experiencing pelvic pain, dyspareunia, and other symptoms.

Key Takeaways:

  • The systematic review included 13 studies comprising 1,597 trans men, with a mean age of 26.7 years (SD: 8.1 years).
  • The pooled prevalence of endometriosis was 8.9% (126/1423, 95%CI: 7.4-10.5%), with a similar prevalence noted in a subset of participants with a surgical diagnosis of endometriosis (9.2%; 50/543; 95% CI: 7.1-11.9%).
  • Non-menstrual pelvic pain was reported by 580 of 1,076 participants (53.9%; 95%CI: 50.9-56.9%).
  • Testosterone use was reported in 926 of 1,413 participants (65.5%; 95%CI: 63.0-68.0%), with a mean treatment duration of 2.4 years (SD: 1.1 years).
  • The study found that endometriosis was stage 1 in 40% of cases (10/25), with a high rate of pelvic pain reported among trans male participants.
  • The study highlighted the need for further research on the prevalence and management of endometriosis in the trans male population.

Statistics:

  • 8.9% of trans men studied (126/1423) had endometriosis.
  • 580 of 1,076 participants (53.9%) reported non-menstrual pelvic pain.
  • 926 of 1,413 participants (65.5%) reported using testosterone.
  • 53.9% of participants reported non-menstrual pelvic pain.
  • 9.2% of participants with a surgical diagnosis of endometriosis reported a similar prevalence.
