Gonadotropin, estradiol, and testosterone profiles in homosexual men.
The authors evaluated the gonadotropin-testosterone-estradiol profiles of four homosexual men and four heterosexual men by a multiple-sampling technique. Although there was extensive overlap between the two groups, the homosexual subjects had higher estradiol levels than the heterosexuals (70.3 +/- 19.8 versus 56.8 +/- 10.7 pg/ml) and lower FSH values (5.1 +/- 1.0 versus 13.2 +/- 3.4 mIU/ml). Testosterone and luteinizing hormone levels were comparable in the two groups. These observations suggest that there may be subtle differences in gonadotropin and estradiol secretion in homosexual subjects that can be detected only by repeated sampling.
