You may have heard the idea mooted a week or so ago by a bioethicist from Dundee, Dr Kevin Smith, who suggested that all young men should be considering freezing sperm as young as 18 as leaving it until later to try to have a child meant that they were more likely to build up mutations. He said the NHS should fund this and claimed it was a practical idea as the children of older fathers were more likely to suffer from genetic diseases.
If you’ve been worrying about this – whether you’re an “older” man or the partner of one – you may be relieved to know that one of the country’s leading sperm experts, Professor Allan Pacey of Sheffield University, described it as “crackers” and one of the most ridiculous suggestions he’d heard in a long time. He said any risks for older men becoming fathers were small and would usually affect those who were over the age of 45. He also made the point that not all sperm will freeze well anyway.
