Erectile dysfunction

Also known as ED and impotence, the loss of the ability to produce and/or sustain an erection despite adequate stimulation and interest.

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.

It was presumed that almost all erection failures were caused by physiological factors like stress, fear, anxiety etc. Though these factors play a significant role, recent researches also indicate impotence as physical inability of blood flow to the penis.

Testosterone and Sex Drive
As age increases, men usually suffer from low sex drive, poor stamina and lack of sexual interest, because most of the testosterone gets bound by sex hormone building globulin. Only 2% of testosterone are left free which are responsible for providing the body with energy and sex drive. Normal men should have 800 free testosterone and lesser number calls for erectile dysfunction.
