目前已有很多临床单位开展了体外受精的工作,用于治疗不孕症,但成功率不同,有人报导移种3个胚胎后的受孕率已可达到30～40%,而有人则尚在为获得第一次或第二次妊娠而努力。这是因为对有关专业知识尤其是胚胎学方面知识的缺乏。和其它医学科研领域一样,体外受精的成功需要在开展的单位中有一整套配合默契的医生与科学家班子,要有丰富的材料来源和完善的设备。现已弄清某些生理因素对体外受精的成功与否有影响。为了一次能获得数个卵细胞用于受精,需给卵泡以刺激。利用自然月经
At present, many clinical units have carried out in vitro fertilization work to treat infertility, but the success rate is different. It has been reported that the pregnancy rate after transplanting 3 embryos can reach 30-40% while others are still at Get the first or second pregnancy and work hard. This is due to a lack of knowledge of relevant expertise, especially of embryology. As in other areas of medical research, the success of in vitro fertilization requires a well-coordinated team of doctors and scientists in the unit to be developed, with a wealth of materials and sophisticated equipment. It has been clarified that certain physiological factors have an impact on the success of in vitro fertilization. In order to obtain several oocytes at a time for fertilization, follicles are required to stimulate. Use of natural menstruation
