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).
测定了男性同性恋者血浆总睾酮(T)和游离睾酮水平。虽然总睾酮水平与异性恋对照组相比无显著差异,但35名男性同性恋者(均值±标准差=10.7±3.3 ng/100 ml)血浆中游离睾酮水平明显低于38名年龄相仿的男性异性恋者(13.3±4.5 ng/100 ml)(p<0.001)。
