Sexual dysfunction and lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH).

Sexuality is an essential aspect of a couple's relationship and has a significant impact on life satisfaction. Benign prostatic hyperplasia (BPH) is a condition that commonly affects older men and is often associated with lower urinary tract symptoms (LUTS) and sexual dysfunction. Men with moderate-to-severe LUTS are at increased risk for sexual dysfunction, including moderate-to-severe erectile dysfunction (ED), ejaculatory dysfunction (EjD), and hypoactive desire (HD). The results of several recent large-scale studies have shown a consistent and strong relationship between LUTS and both ED and EjD. It appears that the pathophysiological mechanisms of LUTS and the related prostatic enlargement of BPH as well as certain treatments for this condition may have an impact on both the erection and ejaculation components of the sexual response. Validated questionnaires that assess sexual function provide clinicians with valuable information to help guide treatment selection decisions. Effective medical therapies for LUTS associated with BPH include alpha(1)-adrenergic receptor antagonists (i.e., alfuzosin, doxazosin, tamsulosin, and terazosin) and 5alpha-reductase inhibitors (i.e., finasteride and dutasteride). The side effects of these medications, including sexual dysfunction, are important distinguishing features. The successful management of patients with LUTS associated with BPH should include assessments of sexual function and monitoring of medication-related sexual side effects. For men with LUTS and sexual dysfunction, an appropriate integrated management approach, based on each patient's symptoms and outcome objectives, is warranted.
