Benign prostate hyperplasia (BPH) is one of the most prevalent diseases in aging men. It may adversely affect quality-of-life due to the presence of low urinary tract symptoms (LUTS) and its effects on sexuality.
The impact of α1-blockers, 5α-reductase inhibitors (5-ARI), and phosphodiesterase 5 inhibitors (PDE-5i) on erectile and ejaculatory functions in men with BPH are covered. Endocrinological aspects have also been addressed, including the management of hypogonadism, which affects many patients with BPH, and the impact of the use of 5-ARI use on bone health.
The adverse-event profile of α1-blockers depends on their affinity for the α1-adrenoceptors rather than selectivity. The probability of ejaculatory dysfunction is highest with silodosin than other nonselective drugs (tamsulosin, alfuzosin, doxazosin, and terazosin). Concerning the impact of finasteride and dutasteride on sexual desire, erectile function, and ejaculation, the vast majority of the studies have shown a low prevalence of treatment-related adverse events. Due to the benefits of erection, PDE5i represents the perfect class of drugs for the treatment of LUTS-BPH in patients with erectile dysfunction. Testosterone replacement therapy could be considered in some hypogonadal patients with BPH. Finally, current evidence support the safety of 5-ARI on bone tissue.
