This is the authors' abstract. We don't add key points for this paper.
Our results indicate that the physical presence of a varicicele is not always associated with an alteration in sperm cell concentration and that a reduction of semen characteristics is more likely in men with reduced sperm counts. Our study also indicates that a higher pregnancy rate after varicocele ligation occurred in wives of patients in the lower sperm count groups. Other forms of therapy also were found to be associated with pregnancy in wives of men with varicoceles. The post-surgical pregnancy rate was 25 per cent compared to 12 per cent in the non-surgical group.
