Impotence is a hugely common condition according to the NHS, which estimates half of men between 40 and 70 will have it to some degree. 

Erectile dysfunction (ED) occurs when a man is unable to establish or maintain an erection, which can lead to decreased sexual activity. 

It can be triggered by a variety of things, including medication, consumption habits and age.

Despite increased awareness of the causes and treatments for ED, the topic largely remains taboo with many men too ashamed to discuss it publicly. 

While it may be embarrassing for some people, the silent stigma surrounding ED makes it an important issue. 

And it seems an increasing number of gents are turning to online forums for advice on prevention and treatment for the common health concern.

Online doctor analysed discussion on popular forum Reddit to identify how men feel about impotence and Viagra, and what they most want to know. 

According to the health experts, a large number of men sought advice on purchasing Viagra online, and the efficacy of a generic alternative. 

The forums also contained testimonials from users who had found success with solutions such as Viagra to treat their ED. 

Interestingly, the analysis also suggested men seeking information about Viagra may be younger than generally perceived.

Urologist Myron Murdock believes it may be due to increased pressure to perform in the bedroom.

The health expert, who is medical director of the Impotence Institute of America, emphasises the need to seek medical counsel before using Viagra. 

It comes after a recent study found Viagra might help prevent heart attacks.

The study, by the Centre for Cardiac Research at the University of Manchester, showed cells from a failing heart actually survive for longer when given a certain drug.

ead researcher Professor Andrew Trafford believes the findings are 'incredibly exciting'. 

He said: "Our studies have shown that drugs normally used for the treatment of erectile dysfunction such as Viagra=85 have a very pronounced effect in slowing progression on heart failure as well as reducing the likelihood of fatal arrhythmias=85 

"Patients who receive Viagra or similar drugs are also far less likely to then go on and die from a heart attack."
