Summary

Testosterone thins vaginal tissue, which can make sex painful. This study used the US PRIDE online study to compare sex lives in 602 people born female who were currently on testosterone and 516 who had never taken it. Pain during sex was strikingly common in both groups: 65% of sexually active people had genital pain or discomfort in the past month, 67% of testosterone users and 63% of non-users. Testosterone users reported more interest in sex and easier orgasm, and slightly more vaginal pain, but no greater satisfaction with their sex lives. The group also reported very high rates of past sexual abuse (78%), depression (81%) and PTSD (40%). Because it is a one-time survey of volunteers, it shows links only, not causes. But it records a large and little-noticed problem of painful sex.

Key findings

  • Nghiên cứu xem xét 1.219 nam chuyển giới và người phi nhị nguyên sinh ra là nữ từ Nghiên cứu PRIDE: 602 người hiện đang dùng testosterone, 516 người chưa bao giờ dùng và 76 người đã ngừng.
  • Trong 1.091 người có hoạt động tình dục, 65% bị đau hoặc khó chịu ở bộ phận sinh dục khi quan hệ trong tháng qua, thường nhất ở âm đạo (52%), sau đó quanh âm vật (29%) và môi âm hộ (25%).
  • Đau bộ phận sinh dục khi quan hệ là phổ biến dù có hay không dùng testosterone: khoảng 67% người đang dùng và 63% người chưa bao giờ dùng.
  • Việc đang dùng testosterone có liên quan đến quan tâm đến tình dục nhiều hơn rõ rệt, đạt cực khoái dễ hơn một chút và đau âm đạo khi quan hệ nhiều hơn một chút.
  • Việc dùng testosterone không liên quan đến sự hài lòng cao hơn với đời sống tình dục, bôi trơn, đau quanh môi âm hộ hay khoái cảm từ cực khoái.
  • Mọi người báo cáo tỷ lệ rất cao trong đời về lạm dụng tình dục (78%), tấn công tình dục (50%), chẩn đoán trầm cảm (81%) và chẩn đoán PTSD (40%).
  • Các tác giả kêu gọi tiếp cận tốt hơn với các điều trị như estrogen âm đạo, mà dưới 5% nam chuyển giới báo cáo từng sử dụng.

Abstract

BACKGROUND: Testosterone use among transgender people likely impacts their experience of sexual function and vulvovaginal pain via several complex pathways. Testosterone use is associated with decreased estrogen in the vagina and atrophic vaginal tissue, which may be associated with decreased vaginal lubrication and/or discomfort during sexual activity. At the same time, increased gender affirmation through testosterone use may be associated with improved sexual function. However, data on pelvic and vulvovaginal pain among transgender men and nonbinary people assigned female at birth are scarce.

OBJECTIVE: This study aimed to assess the association between testosterone and sexual function with a focus on symptoms that are commonly associated with vaginal atrophy.

STUDY DESIGN: We conducted a cross-sectional analysis of 1219 participants aged 18 to 72 years using data collected from 2019 to 2021 from an online, prospective, longitudinal cohort study of sexual and/or gender minority people in the United States (The Population Research in Identity and Disparities for Equality Study). Our analysis included adult transgender men and gender diverse participants assigned female at birth who were categorized as never, current, and former testosterone users. Sexual function was measured across 8 Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction domains.

RESULTS: Overall, 516 (42.3%) participants had never used testosterone, and 602 (49.4%) currently used testosterone. The median duration of use was 37.7 months (range, 7 days to >27 years). Most participants (64.6%) reported genital pain or discomfort during sexual activity in the past 30 days, most commonly in the vagina or frontal genital opening (52.2%), followed by around the clitoris (29.1%) and labia (24.5%). Current testosterone use was associated with a greater interest in sexual activity (β=6.32; 95% confidence interval, 4.91-7.74), higher ability to orgasm (β=1.50; 95% confidence interval, 0.19-2.81), and more vaginal pain or discomfort during sexual activity (β=1.80; 95% confidence interval, 0.61-3.00). No associations were observed between current testosterone use and satisfaction with sex life, lubrication, labial pain or discomfort, or orgasm pleasure.

CONCLUSION: Testosterone use among transgender men and gender diverse people was associated with an increased interest in sexual activity and the ability to orgasm, as well as with vaginal pain or discomfort during sexual activity. Notably, the available evidence demonstrates that >60% of transgender men experience vulvovaginal pain during sexual activity. The causes of pelvic and vulvovaginal pain are poorly understood but are likely multifactorial and include physiological (eg, testosterone-associated vaginal atrophy) and psychological factors (eg, gender affirmation). Given this high burden, there is an urgent need to identify effective and acceptable interventions for this population.
