Children born from frozen embryos are more likely to be girls, fertility doctor claims

Infertile men are more likely to develop aggressive early-onset prostate cancer, research released in July 2018 suggests.

Those who are unable to have children naturally or via IVF are overall 47 per cent more likely to develop the life-threatening condition, while men under 50 have three times the risk, a study found.

Undiagnosed prostate tumours may drive infertility, while low testosterone levels could lead to the development of both conditions, according to the researchers.

Early-onset prostate cancer affects around one in every 1,000 fathers under 50.

Around 35 per cent of men have poor fertility while two per cent are unable to father children.

The researchers, from Lund University, analysed all fathers and their first born children in Sweden between 1994 and 2014.

Information was taken from birth, cancer and assisted reproduction registers.

Fathers who underwent intracytoplasmic sperm injections (ICSI) were compared against those who became parents naturally or via IVF.

ICSI involves doctors injecting a single sperm into an egg. This is different to IVF, which mixes sperm with eggs and allows them to fertilise.

It generally costs up to £1,000, on top of IVF fees, and is recommended for men with very low sperm counts or who have previously struggled to have children.

Results suggest men who have ICSI are at a significantly higher risk of early-onset prostate cancer but not late.

IVF does not influence men’s risk of any type of the disease.

ICSI itself does not raise men’s likelihood of developing prostate cancer, however, infertile men may opt for the treatment in a last ditch attempt to become fathers.
