ED is a common sexual problem for men and its frequency increases with age. It is estimated roughly 30 million men in the U.S. and over 100 million men worldwide suffer from ED. In addition, men with diabetes are three times more likely to have ED. Viagra (sildenafil) is one of the most widely-known prescription drug brand names on the U.S. For many men, the stigma and embarrassment of talking to their doctor about ED has declined since the introduction of Viagra and other PDE5 inhibitors. Today, health care professionals regularly ask men of all ages about sexual dysfunction as part of their regular check-ups. Erectile dysfunction (ED), or the inability to achieve and maintain an erect penis for sexual function, can lead to performance anxiety, a negative impact on self-esteem and personal relationships, and even clinical depression.

In a survey published in BMJ, 62% of men reported a decline in self esteem, 29% reported a negative effect on a relationship, and 21% reported that their relationship had ceased due to ED.
