Abstract
Thirty normogonadotropic oligospermic males were administered Tamoxifen (20 mg/day) for 4 months. A complete evaluation of seminal parameters before and after treatment was performed. An increase of both mean sperm concentration and total sperm count was noted after treatment with Tamoxifen (p < 0.05), whereas no variation was observed for semen volume, sperm morphologic characteristics, or sperm motility. Hormonal patterns of 5 of these subjects before, during, and after 3 months of treatment with Tamoxifen showed a progressive increase of gonadotropin (especially LH) and 17/βE2 values; testosterone variations were minimal, and PRL showed a slight decrease.
