SATURDAY, March 23, 2019 (HealthDay News) -- 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.


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.

The findings are to be presented Saturday at the Endocrine Society's annual meeting, in New Orleans.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
