A case in favour of one sided microscopic vasovasostomy--the New Delhi experience.

Between January 1987 and December 1991 we performed vasovasal anastomosis in 60 patients who had undergone vasectomy for family planning. Of these, 30 patients were randomized for microscopic vasovasostomy and the remaining 30 patients had a macroscopic vasovasal anastomosis. Without exception the procedures were performed on one side only. Out of the 50 patients who reported for follow-up, 44 had return of spermatozoa upon semen analysis. Pregnancy resulted in 30 out of 40 patients who attempted conception (average 75%). There was one complication but no case of surgical trauma- or anaesthesia-related mishap was encountered. The results of the micro and the macro groups are analysed separately in order to draw conclusions.
