Porn could affect men’s brain size, research hints
AFP May 30, 2014
Researchers have found less gray matter in the brains of men who perused large amounts of sexually explicit material.
The research, which appeared Wednesday in the journal JAMA Psychiatry, could not determine if pornography actually caused the brain to shrink, however, and the authors called for additional studies.
“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.
The institute recruited 64 male subjects ages 21 to 45, “with a broad range of pornography consumption.”
The men were not told initially that the research was monitoring their brains on porn, rather that it was “a scientific study including MRI measurements”. They were told during a later phone interview that questions about pornography would be part of the research.
None of the men dropped out.
