【Abstract】 Objective To retrospectively study 400 intracytoplasmic sperm injection (ICSI) cycles by using three different sources of sperm. Method Different male infertility with oligoasthenozoospermia or azospermia was treated by ICSI using sperm from ejaculation, epididymis and testitis. Results In the ejaculation group( n =277),the fertilization rate was 69 6% and the clinical pregnancy rate 28 9%. In the 104 cycles using epididymal sperm, the fertilization and clinical pregnancy rate was 65 9% and 37 5% respectively. And the fertilization and clinical pregnancy of testitis sperm ( n =19) was 65 7% and 21 1%. The difference of fertilization and clinical pregnancy rate among the three groups were not significant.come has nothing to do with the common parameters of semen except that the sperm motility is 0, but the effectiveness of ICSI should be studied by long term observation.更多还原
