Women know when it comes to having a baby they have to beat that biological clock. So what about men? Is there a clock for dads too?
A new study in the current issue of Proceedings of the National Academy of Sciences indicates that becoming a dad later in life may not be as safe as it seems. Researchers looked at the sperm in one hundred healthy men aged 22 to 80. They found that men like women, face an increase in the incidence of down syndrome as they get older.
The older men the study showed more genetic damage in their sperm that could lead to infertility or an increased risk of having a baby with a genetic defect such as dwarfism.
More study is needed, but it may be something for men to discuss with your doctor.
