Impact of Dry Ejaculation Caused by Highly Selective α1A-blocker: Randomized, Double-blind, Placebo-controlled Crossover Pilot Study in Healthy Volunteer Men

Silodosin may adversely affect the subjective orgasmic function by causing an abnormal ejaculation with decreased (or no) semen discharge and a decrease in the number of bulbocavernosus/pelvic floor muscle contractions. Semen passing through the urethra and sufficient rhythmic contraction of the muscle of the pelvic floor may contribute to the subjective pleasure of orgasm.
