A prospective study of midcervical smears from 71 pregnant women was carried out to investigate the validity of Y-body fluorescence as a method for determining intrauterine fetal sex. Endocervical smears were taken below the mucous plug, appropriately stained with Atabrine, and examined using male and female buccal smears as controls. Analysis of the data showed that correct sex of the baby could be predicted only 55 per cent of the time. There was little difference in prediction rate whether the smears were taken in the second or third trimester. The first-trimester smear was the least reliable.
对71名孕妇的宫颈中部涂片进行了一项前瞻性研究，以调查Y体荧光作为确定宫内胎儿性别的一种方法的有效性。在粘液栓下方采集宫颈内膜涂片，用阿的平适当染色，并以男性和女性口腔涂片作为对照进行检查。数据分析表明，只有55%的时间能够正确预测胎儿性别。无论是在孕中期还是孕晚期采集涂片，预测率几乎没有差异。孕早期涂片最不可靠。
