A study from Stanford University in the USA that babies of older fathers may be more likely to health problems. Scientists data on 40,529,905 births in the USA between 2007 and 2016 to whether a father's age adversely affects his child's health. Researchers that compared to babies born to fathers in the 25-to-34 age bracket, babies born to fathers over the age of 45 were at greater risk of born with health problems. These being born prematurely, having a low birth weight or being to a neonatal intensive care unit. The researchers that babies born to older fathers were generally not as healthy as those by younger fathers.

Dr Michael Eisenberg from the Stanford University School of Medicine said: "I think it's important to that the risks we are seeing are modest. So for an individual, the risk may not much." He added that his team's data could a trend that health departments in governments might want to aware of. He said: "At a population level, there may be public health implications of men...waiting longer to conceive." Dr Eisenberg that: "While the oldest father ever is 96, this research that the risk to child and mother may if fathers conceive later."
