Serial Human Chorionic Somatomammotropin (HCS) levels were measured during the last 10 weeks of pregnancy in 57 patients (375 samples). There was a gradual rise from 5.6 microgram/ml at the 30th week to microgram/ml at the 40th week, with a plateau during the last 4 weeks of pregnancy. No correlation could be found of HCS levels with parity, maternal age, maternal height, maternal weight, foetal weight and foetal sex. A weak but significant relationship was found between HCS and plasma oestriol (r = 2.4, p less than 0.001).
对57例患者（共375份样本）在妊娠最后10周期间进行了人绒毛膜生长催乳素（HCS）的连续测定。HCS水平从第30周时的5.6微克/毫升逐渐升高至第40周时的微克/毫升，在妊娠最后4周呈平台期。未发现HCS水平与产次、母亲年龄、母亲身高、母亲体重、胎儿体重及胎儿性别之间存在相关性。发现HCS与血浆雌三醇之间存在微弱但显著的关系（r = 2.4，p < 0.001）。
