  • Look Inside

Methods for collection of spermatozoa from epididymis and testis were examined for the microinsemination by intracytoplasmic sperm injection (ICSI) in 5 azoospermic patients. In 3 patients, spermatozoa were collected by blind epididymal puncture using 23 gauge webbed nee-dle without microsurgically exposing epididymal duct or efferent duct. In the other 2 patients, spermatozoa were directly obtained from 10 to 30mg of testicular tissues by surgical excision. More than 20 spermatozoa were col-lected from each patient. Fertilization was confirmed in 8 of 9 therapentic cycles (88.9%).
