Incidence and remission of erectile dysfunction (ED) and low sexual desire in aging men are predicted by a range of modifiable risk factors, according to research published online in The Journal of Sexual Medicine.

Sean A. Martin, PhD, from the University of Adelaide in Australia, and colleagues described the incidence or remission and biopsychosocial predictors of ED and low sexual desire in a cohort of 810 men aged 35 to 80 years. Multivariate models of ED and low sexual desire were used to examine sociodemographic, lifestyle, and health-related factors.

The researchers found that incidence and remission of ED were seen in 31.7% and 29.0% of eligible men, respectively. The incidence of low solitary and dyadic sexual desire was 17.6% and 8.3%, respectively, while remission occurred in 15.4% and 22.6%, respectively.

Higher age, lower income, higher abdominal fat mass, low alcohol intake, and voiding lower urinary tract symptoms (LUTS) were some of the predictors of incident ED; predictors of remission included lower age, current employment, and absence of voiding LUTS.

Higher age, never having been married, being unemployed, and insufficient physical activity were predictors of low dyadic sexual desire incidence, while being married, higher income, and lower abdominal fat mass were predictors of remission.

For low solitary sexual desire, predictors of incidence included never having been married, being unemployed, low alcohol intake, and hypertension, while being married, employed, higher income, and higher physical activity predicted remission.

“Sexual dysfunction in aging men is a dynamic disorder whose incidence and remission are predicted by a range of modifiable risk factors,” the authors noted.
