He added that his team's data could show a trend that health departments in governments might want to be aware of. He said: "At a level, there may be public health implications of men...waiting to conceive." Dr Eisenberg concluded that: "While the oldest father is 96, this research suggests that the to child and mother may increase if fathers conceive .
