142 Predictors of Intravaginal Ejaculatory Latency Time Among a Cohort of Men Presenting to a Sexual Medicine Clinic

Abstract

Premature ejaculation (PE) is a common male sexual dysfunction and is associated with significant psychological distress. Intravaginal ejaculatory latency time (IELT) is one objective measure utilized in the diagnosis of PE. The objective of this study was to identify factors associated with IELT in a cohort of men presenting to a male sexual dysfunction clinic. A prospective database is maintained of all men presenting to a sexual dysfunction clinic since January 2014. Patients complete an 89-item intake questionnaire that includes information on erectile dysfunction, Peyronie’s Disease, low testosterone symptoms, orgasmic dysfunction, and ejaculatory dysfunction, with one question asking to estimate IELT. Comparative analyses with t-test and linear regression models were used to compare IELT to other patient demographic and pathophysiologic characteristics. A total of 1,406 men completed the intake questionnaire, with 550 responding to the question on IELT. Mean IELT was 8.4 minutes (standard deviation 10.1 minutes). Factors associated with higher IELT included frequency of intercourse (p<0.0001), erection sustainability (p<0.0001), presence of nocturnal erections (p=0.039), IIEF-5 score (p<0.001), and overall satisfaction with sexual relationship (p=0.02). Factors associated with lower IELT included longer duration of relationship (p<0.01) and current alcohol use (p=0.03).
