title: 5 alpha-reduced androgens in the human fetal testis.
abstract: The androgen content was measured in testes from 34 male and in ovaries from 30 female embryos that varied in age from less than 12 to approximately 20 weeks. The 5 alpha-reduced androgens dihydrotestosterone and 3 alpha-androstanediol were found in testes at a level of about a 30th of that of testosterone at all ages examined, whereas very little or no testosterone, androstenedione, or either of the 5 alpha-reduced androgens were detected in the ovaries. Whether dihydrotestosterone plays a role in the development of the testes is unknown.
