Sexual impotence or erectile dysfunction is a usual problem which involves men. It varies in age and increases in the proportion of affected men, from 7 to 8 %, from 20 to 39 years of age; to 55-60 %, in men older than 70 years; according to a study carried out in the USA. It is estimated that at least 10 million men suffer from chronic impotence in the USA, and that at least 20 million more men have less severe forms of erectile dysfunction associated to age, chronic health problems or psychological problems.
Although it was considered that impotence is caused exclusively by psychic causes, latter researches showed that 85-90% of all cases of erectile dysfunction could be related to organic causes, such as peripheral vascular diseases, diabetes, imbalances in the sexual hormones, the effect of medications, etc. This persuaded the medical science team to dig up varied forms of treatment that proved to be effective to a large number of patients. These include oral tablets, vasoactive drugs, vacuum pumps and implantable penis prostheses.
Among the mentioned treatments, taking oral tablets is the most common due to its easiness of procedure. The first tablet approved in the US was the Sildenafil, assessed for its effect on the ability of men with ED to engage in sexual activity and in many cases specifically on their ability to achieve and maintain an erection sufficient for satisfactory sexual activity. One generic version of sildenafil tablet is Kamagra distributed by the Kamagra UK. Kamagra tablets have the purpose of treating men who suffer from erectile dysfunction. It aims to help many men with ED to attain and maintain erection when they are sexually aroused through relaxing and widening the penis to let more blood to flow. These tablets provide the cure for up to 4 hours at 80% of men.
