英文摘要 | The purpose of this study is to evaluate the efficacy and convenience of frozen spermatozoa from microsurgical epididymal sperm aspiration (MESA) with intracytoplasmic sperm injection(ICSI) for the treatment of infertility due to unreconstructable obstructive azoospermia and to compare these results with those when fresh ejaculated spermatozoa are used. A total of 10 consecutive MESA/ICSI cycles and a total of 61 consecutive ejaculated spermatozoa/ICSI cycles were performed from January 1998 to December 1998. The two-pronuclei fertilization rate of metaphase II oocytes and the cleavage rate were 77.3 and 91.8% in the frozen epididymal spermatozoa group, and 78.7 and 96.1% in the fresh ejaculated spermatozoa group. respectively Four womrn became clinically pregnant when frozen epididymal spermatozoa were sued(40% er cycle). Similar results were observed in the group of patients undergoing ICSI using fresh ejaculated spermatozoa(41% per cycle). In conclusion, the combined frozen spermatozoa from MESA and ICSI is highly effective and convenient in the treatment of unreconstructable obstructive azoospermia and its results are also as good as those obrtained from fresh ejaculated spermatozoa in cases of oligoasthenoteratozoospermia. |
