Erectile dysfunction in men is when you find difficulty in getting an erection or keeping a hard penis sufficient for having satisfactory sexual intercourse.
Especially in men older than 40 years old, erectile dysfunction is a very common problem, it happens in about 1 of each 10 men.
In most cases, erectile dysfunction is an underlying cause for another medical problem, but it may also be a problem on its own.
Some men may experience occasional failure to have an erection, and this may be due to many reasons like drinking alcohol, stress, relationship problems, and tiredness.
If this happens in less than 20% of the time, it is not a problem that requires treatment.
