Letting Baby Cry Make Up Male Hormone Testosterone

Biologically, the sex hormone testosterone in a man's body could have increased and decreased depending on age, diet, body condition and situasis. Recent research has shown when he heard a baby crying and could not stop it could lead to increased sex hormone testosterone.

This was revealed from a study conducted by researchers at the University of Michigan, Ann Arbor. According to researchers, these findings may highlight the complex interactions between hormones, behavior and perception of the situation.

"Hormones and behavior are connected in a dynamic and complex, more complex than we think. Hormones may change depending on context and behavior, we can even affect the perception endoktrin. So the situation can lead to different patterns of hormonal response depends on how we behave," said Sari van Anders, neuroendocrinologis from the University of Michigan, Ann Arbor, as reported by LiveScience, Wednesday (14/12/2011).

Previous research suggests that parenting can lower testosterone in men. But recent research shows that babies can actually hear the cry of increasing testosterone.

In that study, researchers set up an experiment using an interactive baby doll that is often used to teach high school students for responsible parenthood. The doll is able to make sounds, including crying out loud. The only way to stop crying is with bracelets swiping sensors on the doll and comfort, just like a real baby.

55 participants were asked to hear the baby crying and trying to calm him down. But before the experiment began, participants were asked to give saliva for testosterone measurements. They were also asked to answer questions about mood.

After that, participants were asked to re-submit saliva samples to measure changes in testosterone. The result, the man who succeeded in calming infants testosterone decreased by 10 percent, while only hear the cry but can not respond to testosterone have increased by 20 percent.

"Hearing the baby's cry is increasingly upset, coupled with shrill cries, without being able to respond may be a danger signal or physiological response to infant protection. That could spur flood of testosterone, as the theory has linked higher testosterone due to some type of behavior," explains Sari van Anders.

According to van Anders, the findings could help expand ideas on parenting, and a simplified perception of testosterone and parents.
