Sexual Dysfunction in Male Patients with Hypertension

Evidence suggests that arterial hypertension, in addition to being a cardiovascular and renal risk factor, may also be associated with an impairment of male sexual function. Since other cardiovascular risk factors, especially diabetes mellitus, have also been shown to correlate with impaired sexual function it has been proposed that sexual and especially erectile dysfunction may, at least in part, represent just another manifestation of atherosclerotic vascular disease.

In addition to hypertension itself, sexual function in male hypertensive patients may also be affected by antihypertensive drug treatment. Available evidence suggests that centrally acting sympatholytic agents, β-adrenoceptor antagonists (β-blockers) and diuretics may have the potential to further impair sexual function. Calcium channel antagonists and ACE inhibitors may be neutral with respect to this endpoint. Preliminary data from several randomised and open studies have suggested that angiotensin II (AT)¹-receptor antagonists may even be associated with an improvement of sexual function.

However, many aspects of the interaction between hypertension, antihypertensive drug treatment and male sexual function remain unclear. Among other factors, the relative contribution of disease labelling both to the higher incidence of sexual dysfunction in hypertensive versus normotensive males and to the negative impact of treatment remains an open question. Furthermore, dose dependence of the observed effects of antihypertensive agents on sexual function, the role of combination therapy and the anticipation of proposed adverse effects of treatment are unresolved issues. Thus, more data from studies of high quality using standardised definitions and procedures are urgently needed to at least partially resolve some of the many open questions.
