Abstract

Although the sperm counts of 5 of 8 adult male-to-female transsexuals were low, other aspects of testicular function were normal. Plasma production rates of testosterone averaged 6.4 mg/24 hours, a value similar to the 5.7 mg/24 hours produced by heterosexual adult men. Production rates of 17β-estradiol and estrone, 55µg/24 hours and 52 µg/24 hours, were also normal. Observed abnormalities of pituitary function and pituitary response to LHRH cannot be explained by abnormal testicular steroidogenesis.
