According to a new study from Rutgers University, women aren’t the only ones with biological clocks turns out men are ticking away too.
Researchers found men who have babies while in their 40s can harm the health of their partners and children.
Officials say most men are unaware of the impacts of their age.
This as the number of babies born to men over the age of 45 increased 10 percent in the US over the past four decades.
Experts say older men who try and make babies put their female partners at risk for things like gestational diabetes and preterm births.
They also put their babies at a higher risk of premature births, late-term stillbirth, and congenital heart disease.
