Ovarian morphology in long‐term androgen‐treated female to male transsexuals. A human model for the study of polycystic ovarian syndrome?

Abstract

Descriptions of the effect of androgenson ovarian human tissues are exceptional. This opportunity was provided for us by 17 women with transsexualism—female to male transsexuals (TSX)—who had been given androgens for a mean period of 21 months before hystero‐salpingo‐oophorectomy took place. Twenty‐nine ovaries from TSX and 14 control ovaries from 13 regularly cycling women were examined. As compared with controls, TSX ovaries were enlarged and displayed a two‐fold increase in cystic follicles and a 3.5‐fold increase in atretic follicles; the ovarian cortex was collagenized and three‐times thicker. Theca interna hyperplasia and luteinization were uniformly observed in TSX cystic follicles. Stromal hyperplasia was a constant finding in TSX ovaries, accompanied by clusters of luteinized stromal cells in 12 cases. Eventually these findings met the histological criteria for the diagnosis of polycystic ovaries. These observations demonstrate that androgens alone may induce polycystic changes. The assumption that the role of androgens is pivotal at the follicular level—inducing follicle growth arrest and accelerating cystic changes—in the genesis of polycystic ovaries is reinforced.
