WASHINGTON – Researchers have found less grey matter in the brains of men who watched large amounts of sexually explicit material, according to a new study.
The research, which appeared on Wednesday in the journal JAMA Psychiatry, could not determine if porn actually caused the brain to shrink however, and the authors called for additional study on the topic.
“Future studies should investigate the effects of pornography longitudinally or expose naive participants to pornography and investigate the causal effects over time,” said researchers at the Max Planck Institute for Human Development in Berlin.
