Answer:During the second and third trimesters of
gestation androgenic C19 steroid, and dehydroepiandrosterone sulfate (DHEA-S), are secreted by the fetal adrenal gland and human placental lactogen (hPL), is secreted by the placenta.
Explanation:During midgestation, the fetal zone occupies 80–90% of the cortical volume and produces 100–200 mg/day of the androgenic C19 steroid, dehydroepiandrosterone sulfate (DHEA-S), which is quantitatively the principal steroid product of the primate fetal adrenal gland throughout gestation. While human placental lactogen (hPL) may be secreted preferentially into the fetal circulation, exerting growth-promoting effects at a time when the rate of linear growth of the fetus is maximal.
