Scientists at Princeton University have discovered that sexual activity can help the brain to grow, according to research done on rats. Virgin rats were also shown to be more anxious generally than those which were sexually active.
Some male rats were given access to sexually receptive females daily for two weeks and a second group were allowed to mate just the once in the same period. Scientists were then able to study the affects the activity had on the brain.
Compared with virgins, both groups had a larger number of neurons in the hippocampus. Sexually active rats also had a rise in the connections of brain cells and grew more adult brain cells.
