Experience with macroscopic vasectomy reversal at the Medical College of Wisconsin.

Thirty-two men underwent vasectomy reversal using loupe magnification at the Medical College of Wisconsin between 1984 and 1991. Semen analysis and pregnancy data were available for 27 of them, and sperm were present in the ejaculate of 24, representing a patency rate of 89%. Pregnancy was established by 11, for a pregnancy rate of 41%. These results suggest that vasovasostomy using loupe magnification provides acceptable rates of patency and pregnancy, although the pregnancy rate appears to be somewhat lower than that reported for microsurgical repair. The lower cost of macroscopic vasectomy reversal may outweigh the potential statistical advantages for some couples.
