The androgen content was measured in testes from 34 male andin ovaries from 30 female embryos that varied in age from lessthan 12 to approximately 20 weeks. The 5-reduced androgens dihydrotestosteroneand 3-androstanediol were found in testes at a level of abouta 30th of that of testosterone at all ages examined, whereasvery little or no testosterone, androstenedione, or either ofthe 5-reduced andfogens were detected in the ovaries. Whetherdihydrotestosterone plays a role in the development of the testesis unknown.
