Babies whose parents were "of advanced paternal age," which is roughly equivalent to those over 35, had a higher risk of complications.

An analysis based on birth data from the last decade in the United States. linked babies of older parents with a variety of risks at birth, including low weight and convulsions.
The Stanford University study published this week in the specialized magazine British Medical Journal, used data managed by the Centers for Disease Control and Prevention -CDC, in its acronym and the National Center for Health Statistics -Ns, in English-.
"We tend to take maternal factors into account when assessing the risks associated with birth, but This study shows that having a healthy baby is a team sport and that the father's age also contributes to the baby's health."said senior author, Michael Eisenberg, of the University of California.

Data from 40.5 million births showed that Babies whose parents were "of late middle age", which is approximately equivalent to those over the age of 35, had an increased risk of complicationsas low birth weight, convulsions and need for aerial attendance at birth.
In general, The higher the father's age, the greater the risk: men 45 years old and over They were 14% more likely to have a premature childand men aged 50 and over had 28% more likely to have a child requiring admission to the intensive care unit.
Even like that, these numbers are not a reason to radically change a life project, since the risks are "relatively low," said Eisenberg.

The researchers organized the information according to the age of the parents and various parameters likely to deviate the link between the age of the father and the results of the birth, such as the race, the level of education, the state marital, history of smoking, health and age of the mother.
The data suggest that When a father reaches the age of 35, birth risks generally increase slightlysince every year that a man is getting older accumulates on average two new mutations in the DNA of his sperm.
For Eisenberg, what surprised the team the most is the relationship that has been found between paternal advanced age and the possibility that the mother develops diabetes during pregnancy.
Couples of men over 45, for example, they were 28% more likely to develop gestational diabetes, compared to parents aged 25 to 34.
