Impotence is more than not being able to have and sustain an erection (erectile dysfunction). There can also be premature ejaculation, and retarded ejaculation. A man can experience one or several other forms of erectile dysfunctions at separate times and on separate occasions.
Failure of sexual power is still regarded as a slur on the manhood of an individual and is seldom admitted to, despite being a very common sexual difficulty. Most men do not take their concerns to their doctor, rather seek treatment from various forms of private assistance.
Oral tablets containing a phosphor-diesterase inhibitor, sildenafil, more commonly known as Viagra, are effective and have become the first line treatment throughout the world.
Although women have reported some benefit from Viagra, it has been widely studied only in men. Another type drug for erectile dysfunction is Levitra. This drug is intended for men only.
Both these medicines start working in 30-60 minutes and their effects usually last from 2-4 hours.
