[Spermiogram findings following antegrade sclerosing of a varicocele].

Antegrade scrotal sclerotherapy is an established method for treatment of varicocele. Semen analysis of 103 patients at least 6 months postoperatively showed an significant increase of progressive motility from 36.5 +/- 20.7% to 51.7 +/- 20%. Evaluation of sperm density and morphology showed a significant increase too. In 79% we found an improvement of sperm density, in 63% of normal morphology and in 71% of progressive motility. There was no correlation between preoperative size of varicocele to postoperative findings in semen analysis. In 42% (n = 38) of inability to conceive the partners became pregnant. These results show that antegrade scrotal sclerotherapy is equivalent to other kinds of operative treatment for varicocele with regard to improvement of fertility parameters.
