Scientists at the University of Pennsylvania determined that the placenta of a pregnant woman can not only absorb nutrients, she is also able to perceive the stress that the expectant mother is experiencing.
As a result of the placenta's reaction to the stress of a pregnant woman, the protein level changes, which is important for the development of the baby’s brain.
Scientists believe this is the key point in the issue of disorders of the development of the nervous system of the baby, including schizophrenia, autism.
Doctors say that stress in the first trimester of pregnancy is directly related to the risk of schizophrenia, especially for male babies.

Also, scientists have found that the stress of mothers during pregnancy increases the stress reaction in the baby, especially if it is a boy.
Doctors have identified a biomarker that shows the differences in the stress responses of male and female children.
The fact is that in the placenta of a woman who bears a boy, one enzyme is missing that performs the function of protecting the brain during fetal development.
If the pregnant woman is faced with stress, the risk of developmental pathologies of the male child is significantly increased.
