Sexual Function and alpha-Blockers.
Community-based studies and surveys have found an association between lower urinary tract symptoms (LUTS) and sexual dysfunction, in particular, erectile dysfunction (ED). The link between ED and LUTS has biologic plausibility. The following 4 theories have been used to explain how these disorders interrelate: 1) decreased or altered nitric oxide synthase/nitric oxide levels in the prostate and penile smooth muscle; 2) autonomic hyperactivity effects on LUTS, prostate growth, and ED; 3) increased Rho-kinase activation/endothelin activity; and 4) prostate and penile atherosclerosis. The relationship of LUTS and sexual dysfunction suggests that treatment of one condition may impact the other.
