Males who have lost their fertility because of cancer could have it restored after testicle tissue is put in deep freeze.
“Our study showed that rat stem cells can be successfully frozen for over 20 years, transplanted into an infertile animal and regenerate the ability to produce sperm, albeit at a reduced rate.”
Around 990 boys under 15 develop cancer every year in the UK and survival is improving but treatments can ruin their fertility. Research suggests frozen testicle tissue could be defrosted and implanted to start making sperm again — even 20 years later.Men with cancer can bank sperm so they can have a baby by IVF but they may be left unable to make more.
