7 Ways Men Change When They Become Fathers
Testosterone—the manly hormone—is responsible for male sex drive, aggression and baldness. Studies show that women find men with higher testosterone levels more attractive. While testosterone evolved to help motivate men to find partners with whom to procreate, having bubbling hormones may not be useful to new dads who should be focusing on Mom and baby—not roaming the savannah looking for hook-ups.A 2011 study found that testosterone levels in new dads drop below the average levels of non-dads. Other studies have replicated these results and found even more interesting tidbits. For example, the more a new dad’s testosterone drops, the greater his involvement is in household chores and baby-related duties.
