‘Men should consider freezing sperm by the time they reach 35’

A new report has concluded that men have a biological clock and they should freeze sperm by the time they reach 35

For many years it has been reported that men do not have a biological clock but this now appears to have become a myth.

The study, which was published this week in the journal, Maturitas, stated that advanced paternal age for men is reached between 35 and 45 and that is the time they should preserve their fertility.

Older men may suffer from decreased fertility and can also be putting their partners at risk of pregnancy complications, such as pre-eclampsia, preterm birth and gestational diabetes.

The study also found that some children may be more likely to develop certain cancers and cognitive disorders, such as autism.

Director of the Women’s Health Institute at Rutgers Robert Wood Johnson Medical School, in New Jersey, US, Gloria Bachmann, said that while it is widely accepted that physiological changes in women over 35 can affect conception.

As lead author of the report, she said: “Most men do not realise their advanced age can have a similar impact.

“In addition to advancing paternal age being associated with an increased risk of male infertility, there appears to be other adverse changes that may occur to the sperm with ageing.

“For example, just as people lose muscle strength, flexibility and endurance with age, in men, sperm also tend to lose fitness over the life cycle.”

The study reviewed 40 years of data and research to reach its conclusions, with Dr Bachmann stating the reasons for the decline in sperm health as lower levels of testosterone and sperm quality over later paternal years.
