自1956年 FuChs 等用羊水细胞预测性别以来,国内外不少学者在这方面行进了深入的研究。1978年我们学习鞍钢铁东医院对早期妊娠胎儿性别的预测方法后,对50例妊娠45～70天,要求人工流产术者,术前行绒毛细胞 Barr 小体、y 小体检查,经术后保留胚胎验证,符合率达98%。但该法未能解决中期妊娠胎儿的预测。据根本地实际情况,我们参考了有关文献后,1979年6月开始,又应用羊水细胞 Barr 小体、y 小体 y 对妊娠14～32周要求引产者110例和要求选择胎儿性别的门诊病人3例,进行胎儿性别预测,经娩出后验证,符合率达100%,现介绍如下:
Since 1956, FuChs and other amniotic fluid cells to predict gender, many scholars at home and abroad have made in-depth study in this regard. In 1978, we studied the method of predicting fetal sex in early pregnancy in Tieshun Hospital of Anshan Iron and Steel Co., Ltd. After the method of predicting fetal sex in early pregnancy was performed in 50 cases, 45 cases of pregnancy were asked for artificial abortion, and Barr bodies, Retained embryo verification, with a rate of 98%. But the law failed to resolve the fetus in the second trimester. According to the actual situation, we refer to the literature, beginning in June 1979, and the application of amniotic fluid cells Barr body, y body y on pregnancy 14 to 32 weeks require induction of 110 cases and require the selection of fetal sex outpatient 3 cases, fetal gender prediction, verified after delivery, in line with the rate of 100%, are described below:
