Whether we like it or not, for many men it gets increasingly difficult to perform sexually as the years advance.

While every individual is different, for a significant percentage of the male of the species, impotency can become an ever worsening problem as the years roll by, although because it is a condition that can be caused by a wide range of medical problems, it is actually a condition that can strike any man at any age.

There are sound scientific reasons why this condition afflicts so many men, and we will consider these reasons in the early part of the book.

Over the past few years, many new drugs have come onto the market to counter impotency, and there is no doubt that many of these drugs are effective for a significant proportion of men who suffer from the condition.

The downside of these preparations is that they are chemically based, because it is well known that pharmaceutical chemicals almost always have side-effects, some of which can be nothing more than unpleasant, while others can be downright dangerous.
