遗传性疾病的产前诊断中,伴性遗传病是羊膜穿刺术的指征,因此这些妊娠的处理,常取决于胎儿性别的测定。羊水培养和核型分析,决定胎儿性别,时间长,费用贵。因此,试用较简单的生化方法测定睾丸酮,以快速测定胎儿性别。本文对812例16～20周孕妇,行羊膜穿刺术,取羊水作睾丸酮及卵泡刺激素(FSH)的放射免疫测定。睾丸酮在41.7毫微克/100毫升时变化系数为
In prenatal diagnosis of genetic diseases, associated genetic disease is an indication of amniocentesis, so the treatment of these pregnancies, often depends on the determination of fetal sex. Amniotic fluid culture and karyotype analysis, determine the gender of the fetus, a long time, expensive. Therefore, try a simple biochemical method for the determination of testosterone for rapid determination of fetal sex. In this paper, 812 cases of pregnant women from 16 to 20 weeks, amniocentesis, amniotic fluid for testosterone and follicle stimulating hormone (FSH) radioimmunoassay. Testosterone has a coefficient of variation at 41.7 ng / 100 ml
