Men should freeze their sperm to protect their future children from health risks, a UK Bioethicist recommends.

A UK bioethicist is recommending all 18-year-olds freeze their sperm to be used later in life to avoid the potential health risks that come with fathering a child at an older age.

According to a study in the journal JAMA Psychiatry as cited by the The New York Times, recent research has shown that late fatherhood is more likely to lead to children with “a range of mental difficulties, including bipolar disorder, autism and schizophrenia”.
