HEALTH: A lot of porn may shrink your brain, researchers say

A recent study says men who watch pornography regularly may be shrinking their brain and dulling their sex driver, the Daily Mail reports.

The study’s lead author, Dr. Simone Kuhn from Berlin’s Max Planck Institute, says the study is the first evidence for a link between porn and a harmful physical change.
Studying 64 men, ages 21 to 45, researchers looked at each person’s brain to see how they reacted to porn. In some, people noticed a difference in their striatums, the “reward and motivation” portion of their brains. Those who had regularly watched pornography had a smaller striatum than those who did not.


But the study has one flaw: It doesn’t definitively answer whether watching porn leads to those changes or whether people born with certain brain types watch more porn.
A professor from Columbia University says more research is needed.
