Trans men appear to have functioning ovaries even taking testosterone injections for a year, a new study has found.
The findings could be important news for trans people who wish to conceive while undergoing gender affirmation treatment.
The findings come from medical investigators at the Tel Aviv-Sourasky Medical Center in Israel.
‘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,’ said Yona Greenman, lead investigator of the study.
‘This information is important for transgender men and their partners who desire to have their own children,’ Greenman said, according to Devdiscourse.
Within the normal range for fertility after testosterone treatment
Researchers conducted a study of 52 transgender men between the ages of 17 and 40.
The trans men were monitored for 12 months after the began taking testosterone injections.
The doctors then accessed the complete results of 32 of the subjects.
Though the researchers found that the level of the Anti-Mullerian Hormone (AMH) diminished after 12 months, the hormone still remained within the normal range for fertility.
The level of AMH is used as an indicator of the so-called ovarian reserve and allows doctors to access the remaining egg supply.
While this is a small sample of the overall trans community, such studies on the effects testosterone injections have on reproductive abilities remain rare.
The researchers will present their findings at the Endocrine Society in New Orleans this weekend.
