Not only expectant moms but also fathers experience hormonal changes

December 18, 2014  18:47

Researchers recently have found out that expectant fathers too go through hormonal changes.

After the investigations women showed large prenatal increases in salivary testosterone, cortisol, estradiol, and progesterone, while men showed significant prenatal declines in testosterone and estradiol, but no detectable changes in cortisol or progesterone.

The results seen in men suggested that impending fatherhood might cause men's hormone levels to change. Researchers didn't know yet why exactly men's hormones were changing; the changes could be a function of psychological changes that men experience as they prepare to become fathers, changes in their romantic relationships, or even physical changes that men experience along with their pregnant partners.

The study is published in American Journal of Human Biology.
