Abstract

Lower urinary tract symptoms (LUTS) and male sexual dysfunction are highly prevalent in ageing men, and are strongly linked. Various treatment strategies for benign prostatic hyperplasia (BPH)/LUTS may affect sexuality, with differences between drug classes and between drugs within a same class. The 5alpha-reductase inhibitors, finasteride and dutasteride, are associated with a greater risk of erectile dysfunction (ED), ejaculatory dysfunction (EjD) and decreased libido than is placebo. Alpha1-adrenoceptor blockers (alfuzosin, doxazosin, tamsulosin, terazosin) show an incidence of decreased libido and ED closely similar to placebo, but differ in their impact on ejaculation, tamsulosin being associated with a higher incidence of EjD (10%) than other alpha1-adrenoceptor blockers (0-1%) and placebo (1%), which is unrelated to retrograde ejaculation or higher efficacy. A randomized, placebo-controlled, cross-over study conducted in healthy volunteers showed that tamsulosin 0.8 mg once daily markedly decreased mean ejaculate volume in almost 90% of subjects, with 35% having no ejaculation. By contrast, there was no lack of ejaculation in subjects receiving alfuzosin 10 mg once daily or placebo. Sperm concentrations in urine after ej...Continue Reading

Adrenergic Receptors: Trafficking

Adrenergic receptor trafficking is an active physiological process where adrenergic receptors are relocated from one region of the cell to another or from one type of cell to another. Discover the latest research on adrenergic receptor trafficking here.
