Histopathological effects of exogenously administered testosterone in 19 female to male transsexuals

Abstract

The effects of exogenously administered testosterone were evaluated in a group of 19 female to male transsexuals who underwent bilateral salpingo-oophorectomy after a variable period of androgen therapy. The findings were compared to those in an age-matched group of 12 patients who underwent pelvic surgery for nonendocrine reasons. The most significant findings in the 19 androgen-treated female transsexuals was the finding of enlarged or borderline enlarged ovaries in 5 subjects. In addition, we found multiple cystic follicles in 17 patients (89.5%), diffuse ovarian stromal hyperplasia in 16 patients (84.2%), collagenization of the outer cortex in 13 patients, and 4) luteinization of stromal cells in 5 patients (26.3%). Findings consistent with polycystic ovaries were thus present in 13 of the 19 patients based on the presence of 3 of the above 4 findings. The data suggest that increased blood levels and presumably increased ovarian concentrations of testosterone may produce the morphological features of polycystic ovarian disease.
