AB - Abstract From July 1992 to May 1994, 31 cases of obstructive azoospermia-induced infertility underwent 35 epididymal sperm aspiration procedures and assisted reproductive techniques. These included in-vitro fertilization (IVF), zygote intra-Fallopian transfer (ZIFT), subzonal insemination (SUZI) and intracytoplasmic sperm injection (ICSI) with embryo transfer or tubal embryo transfer. The motile spermatozoa were retrieved using a gauge 24 Medicut cannula and flush medium. Total oocyte fertilization rate was 23.4% and the clinical pregnancy rate was 12.5% (four out of 32 treatment cycles). Congenital absence of the vas deferens was found in 16 cases (51.6%) and secondary genital duct obstruction was present in 15 cases (48.4%). In all, 29 aspirations were retrieved from the caput of the epididymis and six from the epididymal body or tail. The fertilization rate for the caput spermatozoa was much less than that for other areas of the epididymis (P < 0.05). Though there were no predictable differences in fertilization rates between the congenital and acquired groups, by using epididymal spermatozoa for assisted reproduction, the congenital group seemed to have a stronger tendency to achieve pregnancy (20 versus 5.9%). assisted reproductive technique, epididymal spermatozoa This content is only available as a PDF. © Oxford University Press
