Before and after the appearance of a child in the life of a couple, the attention is generally directed on the changes that occur in the mother’s life and body. The truth is that the fathers also go through a period of biological transformation, depending on the level of involvement in the increase of the fetus.

According to the specialists, after they become fathers, the testosterone level of men decreases significantly. It is a hormonal adaptation, with a functional role, which supports the connection process in a calm and productive manner. As the child develops, and the process of growth and involvement becomes a more relaxed one, the testosterone level is gradually balanced, returning to normal values.
Study. The new father’s role: naturally adaptation
According to the article published by Philippine experts in Proceedings of the National Academy of Sciences, the researchers kept 624 young men, between the ages of 21 and 26, for four years.
In 2025, they were measured the testosterone level in the body. Four years later, in 2009, men who became fathers and assumed the active role, recorded a decrease in testosterone by 26% in the morning and 34% in the evening. Men who did not have children were given much lower decreases in sexual hormone, these being determined by the process of natural aging.
Moreover, fathers who spent more than three hours a day with their child recorded an even lower testosterone level in the body. Therefore, the decrease of testosterone has registered radical changes in the attitude of the fathers, this being a much milder, calm one, developing a more advanced self -control power.
According to the researchers, the father plays an extremely important role in maintaining the family balance. Bilogic speaking, decreased testosterone levels in men who become fathers determine the lack of impulsivity and aggression, causing males to adopt an empathetic personality, developing an advanced emotional availability.
When the testosterone level returns. Health benefits
Experts show that, as the child grows, the testosterone level of fathers is gradually returning to normal values. The child becomes more independent, which induces a sensation of relaxation in the lives of parents.
On the other hand, studies show that a lower level of testosterone, in men, reduces the chances of developing cardiovascular disease and even prostate cancer.
For the new daddy, the decrease of the testosterone level is not a loss, but is part of a biological process necessary to adapt to the new life. The hormone does not disappear permanently, but is balanced according to the family context, encouraging positive emotions, but also active involvement in the child’s growth.
