Motherhood transforms women’s bodies in obvious ways, but did you know men’s bodies evolve when they become fathers? Men’s physical changes are not necessarily apparent to the human eye. Instead, they morph internally. The two main changes are hormonally and cerebrally.
The hormonal change is mainly a drop in testosterone, the male sex hormone. The drop is the male body’s way of preparing for the new role of fatherhood. According to scientists, men with lower testosterone are much more sensitive towards children. They are also more empathetic and motivated to take care of their children.1 One example given by researchers is that of different reactions to a baby crying. They found that men with lower testosterone levels, particularly fathers, are anxious when hearing a baby cry; whereas men with high testosterone levels react with irritation. By the same token, fathers exhibit more patience with daily activities, such as waiting for a parking spot.
Cerebral changes that come with fatherhood also enhance parenting abilities. The outer brain of fathers shows increases in areas that impact planning, focusing and problem-solving. Areas of the brain related to nurturing and risk detection are also activated—which is nature’s way of empowering fathers to know when their babies are safe.2 Dads become more sensitive to others’ pain, which equates to being more empathetic, especially when it comes to children.3
Women are often attributed with having naturally maternal instincts. Women are said to know instinctively what to do with babies, having gone through pregnancy, childbirth and when possible, breastfeeding. Men, on the other hand, are said to “learn” how to be a father. The biological changes that fathers undergo prove that they have naturally paternal feelings that parallel mothers’ maternal instincts. In other words, dads are gifted by nature just as moms are. The difference is that because society doesn’t proclaim it, dads need to be aware of their biological transformation, trust in it, and be confident enough to rely on their nature-given instincts.
There is even a male counterpart to post-partum depression, traditionally attributed only to new mothers. Studies show that one in 10 men experience mental health difficulties in the first six months after a baby arrives.4 This is due partly to the new dad’s expectations of himself to know the right things to do at the right times. It’s a form of self-stress. In addition, the new schedule can create chaos—no time to eat, sleep or exercise as both new parents focus on the baby. These changes in lifestyle patterns impact not only the new mom, but also the new dad. So, new fathers need to be aware of their own mental and emotional states as well as their partners’.
Childrearing experts agree that the fastest way to bond with new babies is to start interacting with them right away. Mothers who breastfeed have a distinct advantage but fathers can dive right in by participating in diaper changing, bathing, bottle-feeding and soon, playing. Talking to babies, feeding them, walking them, learning their milestones and cheering them on—it’s all part of both motherhood and fatherhood.
Nikken wishes all dads a very Happy Father’s Day this coming Sunday!
