[Aromatization of testosterone by the rat embryo testis].
After culturing testes from 19 to 20-day-old Rat embryos in vitro in the presence of 3H-testosterone, 3H-oestradiol could be identified in the culture media by recrystallization to constant specific activity. However, the conversion rate of testosterone to oestradiol was low, approximately 0,03%.
