供卵体外受精(IVF)的成功率取决于胚胎与受者子宫内膜发育是否同步。冷冻胚胎技术的发展简化了同步化问题,改善了供卵IVF的预后。 以无遗传性疾病、感染性疾病和无异常妊娠、异常分娩史的可供卵妇女为对象,从前次月经的第21d每天应用Lupron 1.0 mg进行降调,卵巢功能完全被抑制后,剂量调整为0.5mg,同时以促卵泡成熟激素(FSH)超促排卵。当主卵泡平均直径达到19 mm时,注射人绒毛膜促性腺激素(hCG)10 000 U,36 h后经阴道超声回收卵子。根据精子情况,采用正常浓度或高浓度精子授精,精子活力严重不良者行单精子胞浆内注射,胚胎于
The success rate of egg IVF depends on whether the embryo and recipient endometrial development are synchronized. The development of frozen embryo technology has simplified the synchronization problem and improved the prognosis of ovulation IVF. For non-hereditary diseases, infectious diseases and abnormal pregnancy, abnormal delivery history of ovum women for the object, from the first menstruation on the 21st day Lupron 1.0 mg daily down regulation, ovarian function was completely inhibited, the dose was adjusted to 0.5mg, while follicle-stimulating hormone (FSH) super-ovulation. When the average primary follicle diameter reached 19 mm, human chorionic gonadotropin (hCG) was injected at 10,000 U, and transvaginal sonication was performed 36 h later. According to the situation of sperm, normal concentration or high concentration of sperm insemination, severe sperm motility were intracytoplasmic sperm injection, embryo in
