The significance of gonadotropin-releasing hormone test for predicting fertility after varicocelectomy.
To predict the surgical outcome in 30 infertile men with varicocele, endocrinologic evaluation by the GnRH test was performed before and 6 months after the high ligation of the left internal spermatic vein. Semen analysis was performed and the levels of basal T and PRL were examined preoperatively and 6 months postoperatively. In the pregnancy group, the preoperative excessive response of LH to the GnRH test decreased significantly after surgery. Significant reduction in the LH response is considered to be a valuable parameter for predicting fertility.
