摘要:
目的:分析1例Half-ICSI(一半卵母细胞行常规IVF受精,一半行ICSI)受精完全失败的原因.方法:2015年11月在本院接受辅助生殖治疗的一女患者,采用拮抗剂方案促排卵后,阴道B超监测下穿刺取卵,获得14枚卵母细胞,因患者原发不孕且行3次IUI治疗未孕,男方原发不育,采取Half-ICSI受精方法,预防受精失败.结果:14枚卵母细胞仅见第一极体排出,未见第二极体和双原核,Half-ICSI受精完全失败.结论:ICSI受精完全失败,大多数认为与精子质量有关,推测可能精子缺乏某种因子,不能激活卵母细胞.文献报道4种实验室方法可帮助卵母细胞活化,但由于临床病例有限,还需进一步研究.%Objectives:To analyze the cause of a case of total Half-ICSI (half underwent conventional IVF oocyte fertilization,half underwent ICSI) fertilization failure.Methods:A female patient received assisted reproductive therapy using antagonist program in the hospital in November 2015.After ovulation vaginal B-monitoring,14 oocytes were obtained by puncturing oocytes.For the reason of primary infertility and 3 times of failure in IUI treatment,and her spouse of primary infertility,Half-ICSI fertilization was adopted to prevent fertilization failure.Results:In the 14 oocytes,only the first polar body was found with no second polar body and dual prokaryotic.The Half-ICSI fertilization totally failed.Conclusion:Total ICSI fertilization failure may be due to the quality of sperm,presumably some kind of azoospermia factor fails to activate oocytes.According to laboratory reports,four methods can help oocyte activation,but due to limited clinical cases,further study is required.
