Management of Testosterone‑Induced Vaginal Dryness in Transgender Men

First‑Line Non‑Hormonal Therapy

Prescribe polycarbophil‑based or hyaluronic‑acid‑based vaginal moisturizers to be applied at least twice weekly for 8–12 weeks, covering the vaginal canal, introitus, and external vulvar folds. (American College of Obstetricians and Gynecologists) 1
Recommend water‑based lubricants for sexual activity and avoid petroleum‑based products because they increase the risk of bacterial vaginosis. (American College of Obstetricians and Gynecologists) 1

Low‑dose vaginal estrogen is the most effective treatment for persistent vaginal dryness unresponsive to moisturizers. (National Comprehensive Cancer Network) 3
Formulations include 10 µg estradiol tablets (daily for 2 weeks then twice weekly), a low‑dose vaginal estrogen ring (replaced every 3 months), or vaginal estrogen cream. (National Comprehensive Cancer Network) 3
Low‑dose vaginal estrogen has minimal systemic absorption and does not increase endometrial cancer risk; symptom improvement typically occurs within 2–3 weeks. (National Comprehensive Cancer Network) 3
Because systemic exposure is low, vaginal estrogen is unlikely to interfere with ongoing testosterone therapy for masculinization, but patient preference should be confirmed. (National Comprehensive Cancer Network) 3

Vaginal DHEA (prasterone) improves vaginal dryness and dyspareunia when estrogen is declined or contraindicated. (National Comprehensive Cancer Network) 4
Multiple studies show vaginal DHEA reduces dyspareunia; however, it can raise circulating androgen levels, so monitoring is advised. (National Comprehensive Cancer Network) 4

Refer patients for pelvic‑floor physical therapy if dyspareunia persists despite adequate lubrication. (National Comprehensive Cancer Network) 5
Pelvic‑floor muscle training improves sexual pain, arousal, lubrication, orgasm, and overall satisfaction; many individuals with sexual dysfunction have co‑existing pelvic‑floor dysfunction that responds to targeted therapy. (National Comprehensive Cancer Network) 5

Do not use vaginal laser therapy for vaginal dryness or dyspareunia, as it provides no benefit. (American College of Obstetricians and Gynecologists) 2
Do not delay initiation of moisturizers until symptoms worsen; early treatment helps prevent progressive epithelial thinning. (American College of Obstetricians and Gynecologists) 1
Do not use petroleum jelly as a moisturizer or lubricant. (American College of Obstetricians and Gynecologists) 1

Re‑evaluate patients at 8–12 weeks to assess treatment effectiveness, adherence, and any new symptoms; adjust therapy accordingly, escalating to hormonal options when non‑hormonal measures are insufficient. (American College of Obstetricians and Gynecologists) 2
