We all are probably familiar with such causes of impotence as age, alcohol abuse, smoking or diabetes, but there are other, less obvious reasons that may not contribute to achieving erection at right time.

Blood pressure

To achieve erection, blood must flow to penis. It can be assumed that men with higher pressure are less likely to suffer from impotence. Although studies indicate that about two thirds of men with high blood pressure (hypertension) also face impotence. This is due to fact that sustained high pressure damages blood vessels, making blood supply to penis difficult.

Moreover, high pressure can significantly reduce need for sex and even prevent ejaculation. This is one of interesting facts about male penis. If erection can cope with adverse effects of hypertension – to maintain it, you may still need medication. Diuretics, as well as beta-blockers, often used to reduce pressure, can help improve potency.


Antidepressants cause wide range of sexual complications for both sexes, including impotence for men. Reason for this effect lies in fact that antidepressants change level of such important stimulants of nervous system as serotonin and dopomin, which, in turn, reduces sensitivity of genitals and weakens sexual need and arousal. Increased serotonin levels are most important factor due to its ability to inhibit action of nitric oxide in body, which plays major role in relaxation of smooth muscles that control blood flow to penis.

Extreme humanity

Without a doubt, excessive stress caused by diligent attempts to achieve stable erection may be reason why erection doesn`t occur. Unlike most life tasks, when amount of effort we apply directly affects likelihood of success, excessive psychological effort in name of strong penis can be counterproductive.

Process of constant self-control, in which man continuously concentrates on his own actions during intercourse, can be especially harmful. Instead of pleasure, man constantly asks himself: “How does it go with me? Do I satisfy my partner? Do I have enough erection?”. Man seems to be not involved in physical process and instead observes himself as spectator at sporting event. Associated anxiety can easily lead to feeling of fear and, as result, provoke disappearance of erection.

Peyronie`s disease

Peyronie’s disease is disorder that affects about 1% of men. It consists in curvature of penis, caused by growths of scar tissue. As a result, intercourse becomes painful, and erection weakens. Causes of this disease are unknown, but experts suggest its dependence on genetics, as well as mechanical damage to penis.

In unexcited state, this problem may be invisible, but already during weak erection, when curvature of penis becomes visible, pain may occur. In rare cases, curvature is quite substantial. In 20% of cases, curvature may disappear by itself. However, majority of men suffering from this disease still need medication or surgery.

Anabolic steroids

Many bodybuilders choose anabolic steroids to accelerate muscle growth and restore them after intense workouts. But for these advantages have to pay. Although steroids increase amount of testosterone in blood and in short term can increase sexual desire, long-term use has detrimental effect on body’s testosterone production.

Effect of long-term use of anabolic steroids can range from tightening of testicles to impotence. To eyeballs, body clogged with “artificial” testosterone becomes lazy and stops producing testosterone in right amount, so after stopping use of anabolic steroids, body suffers from lack of this hormone, which, of course, interferes with full erection.

Bicycle riding

Regular cycling is a great exercise that allows you to burn calories and strengthen your heart. However, some experts argue that prolonged cycling may have side effects for man. Being in narrow seat shifts center of gravity of cyclist to crotch – area of ​​skin between anus and testicles. Since perineum plays role of pipeline for nerves and blood vessels that feed penis, prolonged pressure on it can lead to impotence. Men who spend more than three hours a week on cycling are most at risk.
