Health specialists say many men do not realise that if they regularly exceed the safe alcohol limit then they could suffer impotence, also known as erectile dysfunction.

"Many of our patients do not realise that excessive alcohol on a regular basis may result in longer term sexual problems such as impotence, difficulty in ejaculating, a reduction in sexual desire or fertility problems," said Debbie Davies-South, the erectile dysfunction specialist nurse at the Hallamshire Hospital.

The recommended intake of alcohol for men is not to regularly exceed three to four units a day – a unit is half a pint of beer, a small glass of wine and a pub measure of spirits.

Debbie said: "Drinking alcohol is often related to stress, anxiety and depression, factors which are creeping into many of our lives due to ever increasing pressures at home and at work or within our relationships.

"These conditions and their relevant treatments are also contributory factors in causing erectile dysfunction which in itself then causes further stress, anxiety and depression.

"Erectile dysfunction is more common than most men think. It is thought to affect at least one in 10 of the male population."

Impotence can also be linked to heart disease or diabetes.

Debbie said: "Ninety per cent of men who have erectile dysfunction suffer in silence and don't get help because they are embarrassed. It can lead to the break-down of relationships. They may stop socialising and going out. "

But she said effective help was available – such as lifestyle advice and medication to cure the problem.

The team at the Hallamshire see around 100 men a week, mostly in their 40s, 50s, and 60s – but have also helped men as young as 16 and as old as 92.

Men suffering from erectile dysfunction or any other problems of a sexual nature should speak to their GP or contact the specialist team at the Hallamshire on 0114 2712498.
