Antenatal sex was correctly identified in 87.5% of the rhesus monkeys studied by evaluation of sex chromatin bodies in the exfoliated cells present in amniotic fluid. Fluid samples were obtained by either amniocentesis, amnioscopy, or by cesarean section at 80--120 days of gestation. Amniotic fluid concentrations of progesterone, total estrogen, and testosterone were correlated with fetal sex. Concentrations of these hormones decreased over the time period examined. Amniocentesis is a simple procedure which provides for routine fetal sex determination.
通过评估羊水脱落细胞中的性染色质体，在87.5%的恒河猴中准确鉴定出了产前性别。在妊娠80 - 120天时，通过羊膜穿刺术、羊膜镜检查或剖宫产获取羊水样本。羊水孕酮、总雌激素和睾酮浓度与胎儿性别相关。在检查期间，这些激素的浓度下降。羊膜穿刺术是一种简单的操作，可用于常规胎儿性别鉴定。
