2019 — The potential associations of pornography use with sexual dysfunctions: an integrative review

What the study found

This integrative review of observational studies examined whether the frequency of pornography use is linked to sexual dysfunctions such as erectile dysfunction. It concluded that the existing evidence — drawn mostly from cross-sectional investigations and case reports — does not establish that pornography use causes erectile dysfunction, and that longitudinal studies controlling for confounding variables would be needed to settle the question. ^[1]

there is little or no evidence on a causal relationship between erectile dysfunction and frequency of pornography use

Why it matters here

A recurring manosphere claim holds that pornography is a primary cause of erectile dysfunction in younger men. This review is among the most direct academic assessments of that question, and it finds the causal case unproven: because the underlying studies are cross-sectional or single-case, causality "cannot be comprehensively assessed". It is cited on the check does porn cause erectile dysfunction? as evidence that, on current data, the link remains unestablished rather than demonstrated.
