目的 评价体外授精 -胚胎移植 (IVF -ET)和卵母细胞单精子显微注射 (ICSI)技术的疗效。方法 74例不孕患者采用常规超促排卵方案 ,B超监测卵泡成熟后 ,经阴道B超引导下取卵 ,实验室体外培养受精并作胚胎移植。结果 74例共 77个治疗周期中 10 0 8个卵泡发育 ,获卵数 886个 ,获卵率87.90 % ;受精 6 8个 ,受精率 6 8.6 2 % ;5 88个卵裂 ,卵裂率 96 .71% ;移植数 30 0个 ,平均移植胚胎数 4.17±0 .77个。 77周期获临床妊娠 2 8例 ,妊娠率 36 .36 % ,已成功分娩 4例 ( 3例IVF -ET ,1例ICSI)。随访母婴良好。结论 体外受精 -胚胎移植疗效肯定 ,男性严重少、弱精患者可采用卵母细胞单精子显微注射技术
Objective To evaluate the efficacy of in vitro fertilization-embryo transfer (IVF-ET) and oocyte sperm injection (ICSI). Methods Totally 74 infertile women were enrolled in this study. The ovarian follicles were ovarieded with B-ultrasound guided by B-ultrasound. Results A total of 10 0 8 follicles were developed in 74 of 77 cycles. The number of oocytes retrieved was 886, with an egg recovery rate of 87.90%, 68 fertilization and 6 8.62% fertilization rate, 5 88 cleavage rates of 96 .71%; the number of transplantation was 30, the average number of embryos transferred was 4.17 ± 0.77. Twenty-eight cycles of clinical pregnancy were obtained in 77 cycles, with a pregnancy rate of 36.36%. Four cases were successfully delivered (3 IVF-ET and 1 ICSI). Follow-up mother and child is good. Conclusion In vitro fertilization - embryo transfer efficacy is certainly less severe in men, weakest patients can use oocyte sperm injection technique
