Experience wiht vasovasostomy: operative technique and results.

Between 1972 and 1977 vasovasostomy to reverse a previous vasectomy for contraception has been attempted in 27 cases. The procedure was abandoned as a technical impossiblity in only 1 case. The first 17 have been studied and in these there have been 11 pregnancies, 10 of which have already come to term with the birth of normal children, including one set of twins. Of the remainder, 2 are known to have oligozoospermia and 4 have been lost to follow-up although 2 of these were euspermic when last heard of. In spite of the encouraging results it is considered that there are no grounds for altering the present basis of vasectomy counselling in which the operation is described as likely to be irreversible.
