Study finds a third of trans masculine individuals on testosterone still ovulate

Physician-researcher Joyce Asseler and gynecologist Norah van Mello examined the ovarian tissue of transgender people who had their ovaries removed as part of their gender-affirming treatment. They had all used testosterone for at least one year prior to and at the time of the procedure. Their analysis shows that 17 of the 52 study participants (33%) show signs of recent ovulation in the ovarian tissue. The results have been published in Cell Reports Medicine.
