Researchers from the US are ringing a bell for men over 45 who decide to have children, as they have proven that the risks to the health of the child increase as the health of the prospective father increases. the child's health
A number of factors, such as a decrease in testosterone but also the poor quality of sperm can lead to problems to the health of the infant.
Until now, we have known and heard about the problems that a pregnant woman who decided to conceive a child at an advanced age may experience.
What we didn't know is that the age at which a man decides to have children can significantly affect the health of the infant and child.
Study
An American study published in the European journal "Maturitas" and examined the effect of father's age on fertility, pregnancy and child health, pushes men to have children up to the age of 35 and in some cases up to 45.
"Although it is taken for granted that the physical changes that occur in women who become pregnant over the age of 35 can adversely affect conception, the pregnancy process and the health of the child, until now the role played by the age of men in these situations," said researcher Gloria Bachman, director of the Women's Health Institute at Rutgers University School of Medicine.
The effect of parental age on fertility
The research reviewed 40 years of data on the effect of parental age on fertility, pregnancy and child health, given that the age of fathers in the U.S. has increased due to the development of assisted reproduction.
It was observed that in couples where the fathers were older than 45, there was reduced fertility, even in cases where the mother was quite young, under 25.
At the same time, in cases where the father was old, it was observed that in some cases it contributed to the occurrence of diabetes during pregnancy, pre-eclampsia or premature birth.
The dangers to children
Children whose fathers fathered children over the age of 45 were more likely to have low birth weight, lower Apgar scores, birth defects and heart disease, according to the study.
In subsequent developmental stages, this category of children, reports APE, appeared to be more likely to develop cancer, cognitive or psychiatric disorders and autism.
Specifically, increased paternal age was closely associated with the onset of schizophrenia. The chance of developing this psychosis in children with fathers under 25 was one in 141 cases, while in those with fathers over 50 it was one in 47. In autism, the risk begins to increase when fathers are 30 years old, stabilizes after 40 and increases again to 50.
