An article ensures that watching too much porn causes “brain abnormalities” and Japan gets upset

On April 16, 2025, the Japanese news page Nazology published an article titled “People who watch too many pornographic videos have an abnormality in the brain”, which has generated a wave of negative reactions in various Japanese forums. The article explores the effects of excessive consumption of porn on the brain, based on scientific research, but its claims have been received with skepticism and criticism from online users. Let’s see what all this is about.

Nazology’s article highlights how easy access to pornographic videos, driven by technological advancement and internet dissemination, has led to an increase in “porn addiction” cases. According to a 2015 research, men who consume porn often show a reduction of gray matter in brain-related areas of the reward system, which could increase impulsivity and dependency. In addition, a 2016 study reveals that 49% of consumers began to explore genres that previously generated rejection, suggesting an escalation in the search for more intense stimuli.

The text also addresses the effects on personal relationships, pointing out that excessive consumption can reduce sexual satisfaction with the partner and increase problems such as infidelity and emotional distance. As for young people, a 2022 study indicates that 73% of adolescents between the ages of 13 and 17 have seen porn, with a potentially negative impact on their brain development and behavior, as an increase in aggressive behavior.
