Influence of alpha1-adrenoblockers on the ejaculatory function of patients with benign prostatic hyperplasia

BACKGROUND: The cause of ejaculatory dysfunction in patients with benign prostatic hyperplasia can be either the disease itself or its surgical or drug treatment, including the use of alpha1-blockers.

AIM: To study the effect of alpha1-blockers on the ejaculatory function of patients with benign prostatic hyperplasia.

MATERIALS AND METHODS: Under observation were 90 patients with benign prostatic hyperplasia aged from 56 to 79 years, who were distributed into 3 groups of 30 people. Patients of the group 1 were prescribed tamsulosin at a dose of 0.4 mg once a day, patients of the group 2 were prescribed silodosin at a dose of 8 mg once a day, and patients of the group 3 were prescribed alfuzosin 10 mg once a day. Duration of treatment is 4 weeks. To assess the effectiveness of treatment and its impact on copulatory function before and after treatment, patients filled out the IPSS, IIEF-5, ICF and MSHQ questionnaires.

RESULTS: The reduction in the severity of clinical manifestations of benign prostatic hyperplasia and the improvement in quality of life in patients of the three groups were the same. The effect of alpha1-blockers on erectile function has not been noted. A significant decrease in ejaculatory function was revealed in patients of the groups 1 and 2, while in patients of the group 3 no changes in ejaculatory function were observed.

CONCLUSIONS: When planning drug therapy for patients with benign prostatic hyperplasia, it is necessary to take into account the specific effects of different alpha1-blockers on ejaculatory function.
