Abstract: We studied the effect of oral administration of alpha 1-blocker and beta-stimulator on 20 idiopathically infertile men. Bunazosin (alpha 1-blocker, 2 mg/day) and procaterol (beta-stimulator, 100 micrograms/day) were given orally twice daily for 5 months. The administration of alpha 1-blocker and beta-stimulator elicited an increase in sperm output and seminal volume in 16 patients (80%). The increase in sperm output seems to be associated with relaxations of myoid cells, which lead to dilatation of stenotic areas of seminiferous tubules, occurring discontinuously, and subsequent maintenance of good tubular fluid flow. No adverse effects were observed in this series.
