目的 探讨睾丸细针抽吸精子行卵细胞浆内单精子显微注射 (ICSI)的临床价值。方法 本中心在建立稳定的体外受精 胚胎移植 (IVF ET)基础上 ,采用控制性超排卵方案并使用改良的显微操作系统 ,对 8例 (8个周期 )梗阻性无精子症患者以睾丸细针抽吸精子行ICSI术治疗。结果 其受精率、优秀胚胎率和临床妊娠率分别为 80 %(80 / 10 0 )、6 4.3% (4 5 / 70 )和 6 2 .5 % (5 / 8)。结论 睾丸细针抽吸精子经ICSI是治疗梗阻性无精子不育症的有效方法
Objective To investigate the clinical value of fine sperm aspiration of sperms in intracytoplasmic sperm injection (ICSI). Methods Based on stable in vitro fertilization embryo transfer (IVF ET) and controlled ovarian hyperstimulation (OVA) and using a modified micromanipulation system, 8 patients (8 cycles) with obstructive azoospermia developed testicular sperm Needle aspiration sperm ICSI surgery. Results The fertilization rate, excellent embryo rate and clinical pregnancy rate were 80% (80/10), 62.3% (45/70) and 62.5% (5/8), respectively. Conclusions Testicular fine needle aspiration of sperm via ICSI is an effective method for the treatment of obstructive azoospermia
