In market research, men identified three things as essential elements of achieving a satisfactory erection, including:

• The ability to attain an erection
• Erection hardness
• The ability to maintain it for satisfactory sex

Taken together these make up erection quality (EQ).

Many men have been, or will be, concerned with the quality of their erection at some time in their life. It may be an occasional difficulty in getting or maintaining an erection; it could be an erection that is just not as hard as it once was; or it may be a consistent inability to achieve an erection.

It is estimated that over 30 million men in the US have experienced at least partial erectile dysfunction (ED). You are not alone if you experience a loss of erectile function.

Fortunately, if you've noticed changes in your erection there is something you can do about it, talk to your doctor.
