Why don’t men have a menopause? by BBC Health

Some new findings on the effect of older men fathering children has emerged from a study of genes of Icelandic parents and children. Prof Darren Griffin, professor of genetics at the University of Kent, explained what was found from around 80 parents and their children having their genome sequenced for a study.

“We’ve known for a while that the sperm of men can decline with age,” he says.

“What we didn’t know is the extent to which it’s passed on to the offspring.”

When giving his thoughts on the Icelandic study to be published in Nature, he was questioned about why men do not have an age when they become unable to reproduce, in the similar way to women.

“One very interesting idea is that women developed a menopause in order that there would be a lot of grandmothers around that were not of reproductive age but could look after the older children.”
