A new study found that it isn't just women who are more emotional during pregnancy and in the first months of parenthood; men are, too.

 

Led by Lee Gettler at the University of Notre Dame, the study tracked the hormone levels and behaviors of 433 men in the Philippines. What Gettler and his team of researchers found was that men's testosterone levels actually drop when his partner is pregnant while the levels of prolactin — the hormone that produced breast milk in women — rises.

 

 

This chemical shift prepares men to be better caregivers and more emphatic. So if you notice men whose partners are pregnant seem kinder and more sensitive, there's a good chance it's not just your imagination.

The study also found that, like women, men are less interested in sex after the baby is born. While environmental factors such as lack of sleep certainly come into play here, one of the reasons is a drop in testosterone. According to the study, everything returns to normal after about a year.
