People transitioning female to male face issues around future fertility. But new research suggests children in the future are a real possibility for these transgender men. Now, research shows that transgender men can remain fertile after even one year of testosterone treatment. It’s common for transgender men — those who were born female but who identify as male — to undergo testosterone therapy as a gender-affirming treatment. But some may later want children through their own pregnancy or via surrogate, the Israeli researchers explained. “Because the long-term effects of testosterone therapy on fertility are unknown, the current recommendation is to stop testosterone at least three months before fertility treatments,” said lead investigator Dr. Yona Greenman. She heads the Transgender Health Center at Tel Aviv-Sourasky Medical Center. The study included 52 transgender men, aged 17 to 40, who received testosterone therapy over 12 months. They had the expected increase in testosterone blood levels and decrease in estrogen, but their levels of anti-Mullerian hormone (AMH) remained in the normal range for fertility. AMH levels are used to appraise remaining eggs in the ovaries. Average levels in study participants decreased only slightly, suggesting their ovarian function was well-preserved, according to Greenman. Participants also showed no changes in the thickness of their uterine lining. A thick lining is crucial for embryo implantation and a successful pregnancy.
