It feels awful when you cant satisfy your partner sexually. All those blissful years spent with the life partner suddenly seem utopian. Mere thought of sexual separation from your partner generates a gush of negative emotions in your body. Every beautiful thing in life suddenly turns ugly. The sexual fantasy I lived with my partner would never be the same again, you thought with a certain air of despondency. These are the exact feelings experienced if one is suffering from sexual dysfunction.

Sexual dysfunction in women and erectile dysfunction (ED) in men are getting common in this fast-paced instant world. The hormonal, psychological or other medical causes are to be blamed for such sexual adversity. It was a big problem for men till 1998 because the treatments prevalent till then were either surgical or too painful. Viagra (sildenafil citrate) patented by Pfizer Inc. in 1996 came as a breath of fresh air for ED patients. The impotence was not feared any more.

The blue magical pill brought relief on the faces of millions of impotent men and their partners worldwide. Everyone lapped up viagra as soon as it was unleashed in the market. After all, it was promising something back, which is a natural urge of every man.

Viagra works naturally by increasing the blood supply to the penile area resulting in erection. Viagra is fast. The clinical trials proved that in some patients, it works within 14 minutes of intake. Viagra works longer. In some observed cases, its effects lasts for 4 hours.

Viagra has so far been largely proved efficacious in its working. It has brought smiles to millions of faces worldwide. The success of Viagra has motivated other companies to produce even better drugs for the treatment of erectile dysfunction. And some of these efforts have already bore fruits with Cialis and Levitra getting FDA approval in 2003 as prescription pills for the treatment of ED.
