During pregnancy, different protein (hCG and hPL) and steroid (progesterone, oestradiol, oestrone, oestriol) hormones are secreted. hCG, measured by RIA in maternal serum, is a first-trimester trophoblastic function test. The serum levels of hPL reveal the placental function during the two last trimesters of gestation. The main steroid hormones, produced by the foeto-placental unit, are progesterone, oestradiol and oestrone, which control placental function, and oestriol, a good index of foetal vitality.
在怀孕期间，会分泌不同的蛋白质（人绒毛膜促性腺激素和人胎盘催乳素）和类固醇（孕酮、雌二醇、雌酮、雌三醇）激素。通过放射免疫分析法在母体血清中检测的人绒毛膜促性腺激素是孕早期滋养层功能测试。人胎盘催乳素的血清水平揭示了妊娠最后两个阶段的胎盘功能。由胎儿 - 胎盘单位产生的主要类固醇激素是孕酮、雌二醇和雌酮，它们控制胎盘功能，而雌三醇是胎儿活力的良好指标。
