Question

Quizplus · Accepted Answer

It is true that the testosterone level of a new father declines following the birth of his baby. Research has shown that testosterone levels can decrease by as much as 30 percent in men during the first few weeks after their child's birth. This is believed to be a biological adaptation to promote paternal caregiving and bonding with the baby, rather than seeking out other mates.
