1978年,世界上第一个“试管婴儿”娩世,嗣后达十年来,体外受精和胚胎移植术(in vitro fertil-ization and embryo transfer下称IVF-ET)发展和普及甚快。但是,即使在一些以IVF-ET 著称的生殖医疗中心,目前的IVF-ET 的成功率也只在20%左右。如何提高IVF-ET 的成功率,仍是一项极待探究的课题。现将本院1985～19 87年间所作的209例次IVF-ET 的结果,予以回顾性分析,旨于探讨影响IVF-ET 成功的各项因素,希为进一步提高IVF-ET的成功率提供些线索。材料和方法一、病例在本院生殖中心施行IVF-ET 的209例次,受术妇女的年龄为21～40岁,均有规则的月经周期和双相体温,不孕的原因中大部分为输卵管闭塞或切除(159例次,76%),也包括盆腔内膜异位症(33例次,16%)、原发性不孕症(8例次,4%)和丈夫精
In 1978, the first “IVF” in the world passed away. In the next decade, in vitro fertilization and embryo transfer (IVF-ET) have been developed and spread rapidly. However, even in some reproductive health centers known as IVF-ET, the current IVF-ET success rate is only around 20%. How to improve the success rate of IVF-ET is still a subject to be explored. The results of 209 cases of IVF-ET made in our hospital from 1985 to 1987 are retrospectively analyzed to explore the various factors influencing the success of IVF-ET. We hope to provide some evidence to further improve the success rate of IVF-ET clue. Materials and methods First, the cases of 209 cases of IVF-ET in the reproductive center of our hospital, women aged 21 to 40 years, have a regular menstrual cycle and bipolar body temperature, most of the causes of infertility Fallopian tube obstruction or resection (159 cases, 76%), as well as pelvic endometriosis (33 cases, 16%), primary infertility (8 cases, 4%
