Thirty cycles of microsurgical epididymal sperm aspiration were performed on 27 patients presenting agenesia of the vas deferens. Two techniques of microinsemination were used, depending on the quality of the sperm preparation: subzonal sperm microinjection and microdroplet insemination. The results obtained by both microinsemination procedures are presented and discussed.
