During the 16th to 20th weeks of gestation, maternal plasma (mean) level of estradiol is 5.2 ng/mL; estrone, 3.0 ng/mL; estriol, 2.1 ng/mL; progesterone, 4235 ng/dL; and prolactin, 74 ng/mL. Amniotic fluid levels are: estradiol, 446.8 pg/mL; estrone, 234.1 pg/mL; progesterone, 5200 ng/dL; and prolactin, 2633.5 ng/mL. Maternal prolactin concentrations correlate with plasma estradiol. Amniotic fluid prolactin levels correlate significantly with maternal plasma concentrations of estradiol and estrone. The mechanisms for the possible relationship between maternal estradiol and pituitary and decidual tissue production of prolactin are discussed.
在妊娠第16至20周期间，母体血浆中雌二醇（平均）水平为5.2 ng/mL；雌酮为3.0 ng/mL；雌三醇为2.1 ng/mL；孕酮为4235 ng/dL；催乳素为74 ng/mL。羊水水平为：雌二醇446.8 pg/mL；雌酮234.1 pg/mL；孕酮5200 ng/dL；催乳素2633.5 ng/mL。母体催乳素浓度与血浆雌二醇相关。羊水催乳素水平与母体血浆中雌二醇和雌酮浓度显著相关。文中讨论了母体雌二醇与垂体及蜕膜组织催乳素产生之间可能关系的机制。
