title: Significantly decreased apparently free testosterone levels in plasma of male homosexuals.
abstract: Total and free plasma testosterone (T) were determined in male homosexuals. While total T showed no significant difference to a heterosexual control group, apparently free T in plasma was significantly lower (p less than 0.001) in 35 male homosexuals (mean +/- SD = 10.7 +/- 3.3 ng/100 ml) than in 38 male heterosexuals of similar age (13.3 +/- 4.5 ng/100 ml).
