在大鼠和小鼠,着床取决于胚泡与内膜发育的紧密的同步化。在这两种动物以及兔、羊、母牛和猪,子宫只有很短的时期接受胚泡,而干扰同步化在±2天以上,则极少发生着床。这些发现形成了现代节育途径的基础,目的在于发展一些药物以加速妇女卵运输的速率。作者试图评价人子宫冲洗液对离体胚泡的影响。从正常经产妇女在月经周期的各个阶段收集子 In rats and mice, implantation depends on the close synchronization of blastocyst development to the intima. In both animals, as well as in rabbits, sheep, cows and pigs, the uterus received blastocysts for only a short period of time, with interference synchronized over ± 2 days, implantation rarely occurred. These findings form the basis of modern methods of birth control, with the aim of developing drugs to accelerate the rate of egg transmission in women. The authors attempted to assess the effect of human uterine flush on isolated blastocysts. Women from normal menstruation were collected during all stages of the menstrual cycle
