    Abstract:
    OBJECTIVE: The aim of this study was to examine, retrospectively, the efficacy of intracytoplasmic sperm injection (ICSI) in the treatment of male infertility and idiopathic infertility. METHODS: From November 1995 to January 1998, 140 couples (156 cycles) received ICSI because of severe male factor infertility or idiopathic infertility in our assisted reproductive technology center. The treatment cycles were divided into two groups, group I included 74 cycles done before May 1997, group II included 82 cycles done after May 1997. Mature oocytes were selected for microinjection. RESULTS: No differences were observed between the two groups in the number of mature oocyte and the total cleavage rate. Oocyte survival rate, normal fertilization rate, embryos of good morphology rate and clinical pregnancy rate were significantly higher in group II than that in group I. CONCLUSION: ICSI procedure does affect the quality of embryos. With the improvement of ICSI technique, ICSI should be the treatment of choice for male infertility and idiopathic infertility.
