About the study

The effects of pornography use on male sexual health remain uncertain, with mixed findings across existing literature and substantial variability at the individual level. This observational study is designed to help participants evaluate how a 30-day period of pornography abstinence affects their own sexual health and well-being, with a specific focus on nocturnal penile tumescence as a physiological biomarker.

Participants will complete a short baseline observation period during which they maintain their usual pornography consumption patterns, followed by a 30-day abstinence period. Objective nocturnal erection data will be collected using a connected wearable device, alongside validated self-report questionnaires assessing erectile function, sexual desire, mood, energy, and emotional well-being. Participants serve as their own control, allowing for within-person comparisons of outcomes before and during the abstinence period.
