宫颈粘液的质量是决定妇女受孕的原因之一。宫颈的功能可以用性交后试验(PCT)研究。体外精子穿透试验可用简易的玻片法。Kremer试验是将薄毛细管内充满粘液后精子向上游动,发展Kremer试验的解释,Kremer及Moghissi提倡用提供者的精液及宫颈粘液。由于完全交叉的Kremer试验步骤至今尚无临床评价,因此作者从事本项研究。作者对176对PCT试验结果异常的不孕夫妇在4年间进行了完全交叉的Kremer试验。用过去Kremer试验有良好结果或最近妊娠的男性精液和女性宫颈粘液,在估计排卵日与不孕夫妇的精液和宫颈粘液配伍成不同对,进行交叉试验。宫颈粘液
Cervical mucus quality is one of the reasons that determines the woman conceives. The function of the cervix can be studied using the Postnatal Test (PCT). In vitro sperm penetration test using a simple slide method. The Kremer test, which moves the sperm upwards after filling a thin capillary with mucus, develops the Kremer test, and Kremer and Moghissi advocate the provider’s semen and cervical mucus. The authors did the research because there was no clinical evaluation of the completely crossed Kremer test procedure. The authors conducted a complete crossover Kremer test of 176 infertile couples with abnormal PCT test results over a 4-year period. Male subjects and female cervical mucus with good results or with recent pregnancies were tested with Kremer in a crossover test using sperm and cervical mucus compatible with infertile couple on the estimated ovulation day.
