Plasma estrone, dihydrotestosterone, luteinizing hormone (LH), and percentage-free testosterone levels were determined in 26 predominantly or exclusively homosexual males (20 to 33 years of age) and in an age-matched control group. Although the homosexual and control groups showed a broad overlapping for all hormonal factors measured, highly significant differences between the groups were found without exception. The medians of the homosexual group (control group) and the significance levels for the two-sample rank tests were as follows: estrone 3.07 (2.43) ng/100 ml, P less than .01; dihydrotestosterone 66.0 (49.2) ng/100 ml, P less than .01; percentage-free testosterone 10.7% (9.7%), P less than .02; LH 35.1 (24.9) ng/ml, P less than .001. These findings can in part be explained by the higher LH secretion in the homosexual subjects.
对26名主要为同性恋或完全为同性恋的男性（年龄在20至33岁之间）以及一个年龄匹配的对照组测定了血浆雌酮、双氢睾酮、促黄体生成素（LH）和游离睾酮百分比水平。尽管同性恋组和对照组在所有测定的激素因素方面显示出广泛的重叠，但两组之间毫无例外都发现了高度显著的差异。同性恋组（对照组）的中位数以及两样本秩和检验的显著性水平如下：雌酮3.07（2.43）ng/100 ml，P<0.01；双氢睾酮66.0（49.2）ng/100 ml，P<0.01；游离睾酮百分比10.7%（9.7%），P<0.02；LH 35.1（24.9）ng/ml，P<0.001。这些发现部分可以通过同性恋受试者中较高的LH分泌来解释。
