Erectile dysfunction and premature ejaculation in men who have sex with men.
BACKGROUND
Quantitative research into sexual function and dysfunction in men who have sex with men (MSM) has been sparse due in large part to a lack of validated, quantitative instruments for the assessment of sexuality in this population.


OBJECTIVE
To assess prevalence and associations of erectile problems and premature ejaculation in MSM.


METHODS
MSM were invited to complete an online survey of sexual function. Ethnodemographic, sexuality, and health-related factors were assessed.


METHODS
Participants completed a version of the International Index of Erectile Function modified for use in MSM (IIEF-MSM) and the Premature Ejaculation Diagnostic Tool (PEDT). Total score on the erectile function (EF) domain of the IIEF-EF (IIEF-MSM-EF) was used to stratify erectile dysfunction (ED) severity (25-30 = no ED, 16-24 mild or mild moderate ED, 11-15 moderate ED, and ≤10 severe ED). PEDT scores were used to stratify risk of premature ejaculation (PE, diagnosed as PEDT score ≥9).


RESULTS
Nearly 80% of the study cohort of 2,640 men resided in North America. The prevalence of ED was higher in older men whereas the prevalence of PE was relatively constant across age groups. Multivariate logistic regression revealed that increasing age, HIV seropositivity, prior use of erectogenic therapy, lower urinary tract symptoms (LUTS), and lack of a stable sexual partner were associated with greater odds of ED. A separate multivariate analysis revealed that younger age, LUTS, and lower number of lifetime sexual partners were associated with greater odds of PE.


CONCLUSIONS
Risk factors for sexual problems in MSM are similar to what has been observed in quantitative studies of non-MSM males. Urinary symptoms are associated with poorer sexual function in MSM.
