[The rate of induction of estrogen synthesis in male chick embryos treated with estradiol].
When cultured in vitro in the presence of 14-14C-dehydroepiandrosterone, the testes from 8-day-old chick embryos treated with oestradiol benzoate at 6 days synthesize radioactive oestrone and oestradiol within 24 hours. Radioactive oestradiol forms also, within 24 hours, when the 8-day-old testis is simultaneously cultured in the presence of 4-14C-dehydroepiandrosterone and nonradioactive oestradiol.
