There are 160,000 men with prostate cancer across the UK who cannot enjoy a full sex life, with the problem set to get worse, a charity has warned.
Men with prostate cancer are four times more likely to experience erectile dysfunction than those without, according to Macmillan Cancer Support.
An increasing number of sufferers are now receiving surgery, radiotherapy and hormone treatment, all of which can lead to issues with erectile dysfunction, according to the charity.
There are currently 250,000 men in the UK living with prostate cancer – a number set to soar to 620,000 by 2030.
That could lead to there then being 390,000 men in the UK unable to get an erection.
Professor Jane Maher, chief medical officer of Macmillan Cancer Support, said: "These figures highlight a major issue facing prostate cancer patients."
Prostate cancer survivor Jim Andrews (63), from London, said his sex life was ruined after he was diagnosed with cancer.
"My sex life had been destroyed. I was devastated," he said.
