Trans Men’s Ovaries Function After One Year of Testosterone Treatments

Transitioning transgender men who hope to reproduce receive good news as a new study shows that trans men’s ovaries appear to function even after a year of injecting testosterone, according to Devdiscourse.

The study was conducted by doctors from the Tel Aviv-Sourasky Medical Center in Israel. Fifty-two transgender men, ages 17 to 40, were studied for a year after receiving testosterone injections. The doctors had access to the complete results of 32. While this is a very small sample size, studies of this kind focusing on the reproduction of the transgender community remain relatively rare.

While the levels of the Anti-Müllerian hormone (AMH), a hormone produced by reproductive tissues, diminished after a year of testosterone treatment, they remained in the normal range of reproduction. Levels of AMH allow doctors to access the remaining egg supply in a patient by acting as an indicator of the ovarian reserve.

“Our research shows for the first time that after one year of testosterone treatment, ovary function is preserved to a degree that may allow reproduction,” Yona Greenman, the lead investigator of the study, said. “This information is important to transgender men and their partners who desire to have their own children.”
