INTRODUCTION: Despite evidence to the contrary, a number of advocacy and self-help groups persist in claiming that internet pornography use is driving an epidemic of erectile dysfunction (ED). AIM: The present work sought to explore whether mere pornography use itself and self-reported problematic use of pornography are related to ED, both cross-sectionally and longitudinally. METHODS: A series of 3 samples of sexually active men who also used pornography were collected: a cross-sectional sample of undergraduate men in the United States (n = 147), an online sample of men derived from a larger sample that was matched to U.S. nationally representative norms (n = 297), and a 1-year, 4-wave longitudinal sample of adult men derived from an online convenience sample (Mechanical Turk: time 1, n = 433; time 2, n = 223; time 3, n = 202; time 4, n = 196). Pearson correlations and cross-sectional structural equation models were conducted in each sample. Latent growth curve analyses were conducted in the longitudinal sample. MAIN OUTCOME MEASURE: The primary outcomes of interest were cross-sectional and longitudinal reports of erectile functioning as measured by the International Index of Erectile Functioning 5. RESULTS: Across all 3 samples, there was evidence of a positive, cross-sectional association between self-reported problematic use and ED, but no consistent association between mere use itself and ED. In our longitudinal sample, there were correlations among baseline pornography use, baseline self-reported problematic use, and prospective ED at times 2-4; however, latent growth curve analyses demonstrated no significant relationships between any pornography-related variables and trajectories of ED. CLINICAL IMPLICATIONS: These results suggest that among non-treatment-seeking pornography users, self-reported problematic use likely is associated with concurrent reports of ED, but that the links between these variables are not directional or causal in nature. STRENGTH & LIMITATIONS: This work is the first work to systematically examine the links between self-reported problematic use of pornography and ED, and it did so in a variety of samples, using both cross-sectional and longitudinal methods. Even so, the work relied exclusively on self-report methods, and did not control for medical covariates that may be related to the experience of ED. CONCLUSION: In conjunction with prior literature, we conclude that there is little or no evidence of an association between mere pornography use and ED, consistent evidence of an association between self-reported problematic use and ED cross-sectionally, and no evidence of causal links between any pornography variables and ED.
