Maternal plasma estrogens after dehydroepiandrosterone-sulfate injection into the fetus.
To study the biogenesis of estrogens by the fetoplacental unit in late pregnancy, dehydroepiandrosterone sulfate was injected directly into the fetus and maternal blood sampled at intervals for 2 hours thereafter. There was no increase of estrone, estradiol, or estriol concentration in the maternal circulation.
