Erectile Disfunction Also known as ED and impotence, the
loss of the ability to produce and/or sustain an erection despite
adequate stimulation and interest.
The greatest nightmare a man can have is becoming impotent in
his prime. Impotence is a bane on the male population worldwide and it
is growing. Our modern lifestyle is to blame. What with excess use of
alcohol, drug abuse, overwork etc. Even our modern way of nutrition all
contribute to the escalating problem of erectile dysfunction.
Thanks to various researches, this problem can be solved. Lucky us. The
difference between sexual performance of a woman and a man is that a
woman can perform in sex even when not aroused but a man? He needs
arousal and hard erections in order to perform as expected of him. There
are various medications out there all claiming this and that. One can
not be too careful to choose the right and effective ones.

Physiology of Erection
The penis is made up of 3 chambers, two corpora cavernosa – the
erectile tissues and one corpus spongium. Secretion of nitric oxide (NO)
leads to sexual arousal, blood vessels dilate and blood fills the
penis. This typically lasts until arousal is diminished or orgasm is
achieved. Penile erection is mediated by the nervous system. On stimulation
causes vasodilatation and relaxation of the cavernosal (penis) smooth
muscle, which ultimately leads to penile erection. Nitric oxide is
released from nerve endings by activating guanylate cyclase and
resulting into cGMP which is the secondary messenger that causes smooth
muscles relaxation leads to venous engorgement and penile tumescence. Recent research has helped to change our thinking about the most common causes of sexual dysfunction.
For a long time it was assumed that almost all erection failures were
caused by psychological factors -- stress, anxiety, and fear. While
these factors can play a significant role, most experts now believe the
major cause of impotence is physical. Simply stated, anything that
interferes with blood flow to the sexual organs interferes with sexual function.
occurs when the blood flow to the penis increases, as a man becomes
sexually aroused. This occurs via the secretion of a chemical called
nitric oxide (NO). Blood vessels going to the penis dilate, and blood
fills the penis causing it to become engorged. This will typically last
until arousal is diminished, or orgasm is achieved.
The penis has
3 chambers, which fill with blood during an erection. When you're not
sexually aroused the penile chambers are open and allow for the flow of
blood through them. When sexual arousal occurs, the chambers remain open
and the exit gates close. When this occurs the blood that remains in
the penis gives you your erection. Once the penile gates close the
amount of blood in the chambers will determine how you perform.
