A study conducted by Northwestern University in Chicago, Illinois shows that testosterone levels lower in men who become fathers.
Researcher Lee Gettler says,
“Men are, to a certain degree, hardwired to take care of their kids…this is important because traditional models of human evolution have portrayed women as the gatherers that take care of the kids and stay behind.”
In the meantime, women’s estrogen levels skyrocket during pregnancy, but after the kid is born the man loses some testosterone and turns into a lady too? Hot.
The experiment was tested out on 465 different men for the Cebu Longitude Health and Nutrition Survey in the Phillippines…
It was discovered by accident that after half of the participants became fathers they experienced testosterone level drops of about 30%.
The men who stayed single showed only a small decline, one that is commonly related to aging. (About 12 to 15 percent)
