TIG -- May 1986 pubertal events appear tobe effected mainly throul~h the actions of testosterone, since plasma concentrations and production rates for dihydrotestosterone are h~ the female range or slightly abOve ~°. In contrast, prostatic development and/or enlargement, ache, normal male facial and body hair, and temporal recession of the hairline did not occur in affected male adults, and appear to be mainly mediated by dihydrotestosterone. The conversion of testosterone to dihydrotestostero one and nuclear bL~ding of the 5~-dihydrotestosterone receptor complex are not characteristic of all androgen- responsive tissues. Since both androgens share a common receptor, it is puzz]hlg that the effects of dihydrotestosterone, particularly in u~ro, are not mimicked by testosterone in dihydrotestosterone- dependent areas. There are two possible explanations: the receptor at certain target sites is modified so that it favors 5~-dJhydrotestosterone over testosterone 2z, and/or the 5~-dihydrotestosterone receptor complex has a higher Af6nity for the acceptor sites in the nuclear chromatin ~. In some affected subjects with descended testes, testicular biopsy has demonstrated complete spermato- genesis, suggesting that testosterone may be more important ~ dihydrotestosterone in the process of
