New study indicates that fatherhood after the age of 40 is a common habit in the modern society
The study published in the Human Reproduction journal has assessed the age that men across the U.S. become fathers. Surprisingly, the average age has increased significantly over the last 40 years. The numbers rose progressively, as during 1972 men had babies around 27 years of age.
Moreover, according to the New York Times, Asian fathers hold the record for the oldest fathers in the world, while the Hispanics are the youngest.
The research, led by Dr. Michael Eisenberg from the Stanford University Medical Center, shows that more than 9 per cent of the babies born every year in the U.S. have fathers passed 40. Outside the U.S. the percentage is even higher, as U.K. has registered a 40 per cent live births with fathers between 35 and 54 years of age.
But what about the implications of middle aged fatherhood?
If talking advantages, one of them would be the significantly higer resources, in terms of career, education and maturity. However, when it comes to risks Professor Eisenberg highlighted that men were not assessed as intensively as women, medically speaking. Nevertheless, the quality of semen could decline, and the children could present more birth defects when compared with babies conceived with younger fathers.
“It’s kind of like buying two lottery tickets, instead of one,” commented Eisenberg, who explained that its statement does not necessarily increases the chances of having healthy children, free of autistic specter disorders, neurological or psychiatric conditions.
