“My penis doesn’t get hard, why?” well keep reading:
Erectile dysfunction (ED or "male impotence") is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis sufficient for satisfactory sexual performance. An erection occurs as a hydraulic effect due to blood entering and being retained in sponge-like bodies within the penis. The process is most often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the pelvis. Erectile dysfunction is indicated when an erection is consistently difficult or impossible to produce, despite arousal.
There are various and often multiple underlying causes, some of which are treatable medical conditions. The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects. It is important to realize that erectile dysfunction can signal underlying risk for cardiovascular disease. I guess in some cases it also could signal the looks of the partner ;)
There is often a contributing and complicating and sometimes a primary psychological or relational problem. Psychological impotence is where erection or penetration fails due to thoughts or feelings (psychological reasons) rather than physical impossibility, this can often be helped by doing regular exercises. Erectile dysfunction, tied closely as it is to cultural notions of potency, success and masculinity, can have severe psychological consequences. There is a strong culture of silence and inability to discuss the matter. In reality, it has been estimated that around 1 in 10 men will experience recurring impotence problems at some point in their lives. Well it seems to be pretty common then, I better be prepared :o
Surgical intervention for a number of different conditions may remove anatomical structures necessary to erection, damage nerves, or impair blood supply. Complete removal of the prostate gland or external beam radiotherapy of the gland is common causes of impotence; both are treatments for prostate cancer. Some studies have shown that male circumcision may result in an increased risk of impotence (Palmer J (1979), Chen Z (2004)), while others have found no such effect (Albertsen P (2002), Erden D (2004), Sheriff M (2005)), and another found the opposite (Zuckerman E (1997)).
Excessive alcohol use has long been recognised as one cause of impotence, leading to the euphemism "brewer's droop," or "whiskey dick", Shakespeare made light of this phenomenon in Macbeth.
A study in 2002 found that ED can also be associated with bicycling. The number of hours on a bike and/or the pressure on the penis from the saddle of an upright bicycle is directly related to erectile dysfunction (Turner T (2002)).
Some evidence suggests that smaller penis size is associated with erectile dysfunction (Abu-Hijleh M (2005)).
So I guess to conclude this, you shouldn’t think that you’re safe, since 1/10 get this someday, even if you’re up there in age and never have had it. So to lower the risk of this, be sure to do some regular penis exercises, and just keep in shape if you know what I mean ;)
