Pornography Abstinence and Nocturnal Erections in Adult Men

This single-arm, real-world observational study evaluates the association between pornography abstinence and changes in nocturnal penile tumescence, sexual function, and psychosocial outcomes in adult men.

During an initial baseline phase, participants continue their typical pornography use while collecting objective nocturnal erection data and completing baseline questionnaires. Participants then enter a 30-day abstinence period, during which they attempt to refrain from pornography use. Abstinence adherence is self-reported, with lapses logged as observational data rather than protocol violations.

Nocturnal penile tumescence is assessed nightly using the Adam Sensor, a non-invasive wearable device that measures changes in penile circumference during sleep. Additional outcomes are assessed using validated questionnaires administered at baseline and at weekly intervals. The study is exploratory and signal-detecting in nature and is not designed to establish causality.
