Impending fatherhood has a significant effect in the bodies of the fathers. According to a research by the University of Michigan, approaching fatherhood affects the level hormones such as testosterone and also estaradiol. The research showed that the psychological feelings that they experience as they wait to become fathers.
The changes in the hormonal balance in the body of the fathers can have significant implications on their paternal behaviors after their babies arrive. Normally, these changes come in the last moments of expectancy before the child is born.
The changes in the level and secretion of hormones in the bodies of expectant fathers are intense among the first time fathers. Such fathers are experiencing fatherhood period for the first time in their lives. The following are some means to detect the changes:
The changes in the level of hormones among expectant fathers can be detected through testing the samples of their saliva. Saliva contains three male hormones including testosterone, estradiol, and cortisol.
These hormones can easily be tested through checking their presence level in the saliva. However, their presence in the saliva samples in different since these hormones are associated with different purposes in the bodies of men.
According to the University of Michigan’s research on the changes of hormones among expectant fathers, the men who are waiting for their babies to be born have significant declines in the level of testosterone and estradiol in their bodies.
The age of an expectant father also contributes to the specific decline in the level of hormones as showcased in the saliva samples. The research showed that men in the age brackets of 18-45 years show the highest decline in the level of testosterone and estradiol in their bodies.
However, despite the fact that the expectant fathers have a change in the level of hormone in their bodies, they do not have any psychological effect which is as a result of this significant change. This can be seen through the level of cortisal in their bodies.
From the saliva samples used in the research, the level of cortisal was noted to be at the unchanged despite the changes in the other hormones. Therefore, it is evident that men do not suffer any psychological changes such as stress and depression in their bodies at this moment.
Contrary to the case with men, women show increase in the level of hormones in their prenatal stage. Mainly, women show an increase in four major hormones including progesterone, estrogen, oxytocin, and prolactin.
There is increase in hormones such as progesterone level especially in prenatal stages among women. Progesterone guides women in their maternal behavior and social closeness. However, the level of hormones decreases among men especially testosterone.
Testosterone and estradiol hormones play a major role in the bodies of men. However, their level during impending fatherhood declines due to the anticipation of becoming a father. Although the changes are significant and strongly evident, they do not result to any psychological and behavioral changes in men. This is seen by the maintained level of the stress hormone (cortisal).
