IVF后3PN卵子中多余的原核多为精子来源，没有移植价值；ICSI后3PN中多余的原核非精子来源，ICSI后3PN中二倍体率与IVF相比显著增高，在患者ICSI后无2PN卵子时可考虑行植入前遗传学诊断。

ObjectiveTo study the spermicidal and antibacterial effect of ethanol extract of Rhynchosia volubilis Lour roots.

目的研究鹿藿醇提取物的体外杀精及抗菌作用。方法（1）鹿藿醇提取物按照国际计划生育基金会认可的杀精子实验方法，对10只小鼠附睾精子悬液和10例人精液进行体外杀精实验。
