With either mental or physical stimulation, your brain signals the nerve ending in the penis to release nitric oxide. Nitric oxide relaxes or dilates blood vessels, enabling them to open up and bring more blood to the penis and helping to create an erection. In this article, we will discuss the risk factors of erectile dysfunction:
1. Chronic health conditions
People suffering from chronic diseases have a high risk of erectile dysfunction. Chronic diseases such as:
a) Heart diseases are caused by cholesterol building up in the arteries and blood vessel resulting in inadequate blood flow into the penis.
b) Diabetes with unhealthy diet causes high levels of glucose build-up in the bloodstream resulting in narrowed arteries and blood vessels that prevent adequate blood from entering the penis.
c) Prostate enlargement and chronic prostate: Inflammation of the prostate also reduces the blood flow entering the penis resulting in erectile dysfunction.
Other chronic diseases affecting organs like the lung, liver, and kidney also can lead to erectile dysfunction because of inflammation, inadequate blood flow or hormonal imbalance.
2. Aging
Aging results in more testosterone to be converted to dihydro-testosterone causing erections to take longer to develop and to need more direct touch to the penis.
3. Nerve damage
It is obvious that any damage to the nerve that directly controls erections can cause temporarily erectile dysfunction.
4. Medication
The side effects of some medications used to treat high blood pressure, depression, and prostate enlarged may interfere with nerve impulses and reducing the blood flow to the penis.
5. Prolong cycling
Prolong cycling over an extended period and pressure from a bicycle seat compresses nerves and blood flow to the penis, leading to temporary erectile dysfunction.
6. Psychological conditions
Other psychological conditions such as depression, anxiety and stress also contributes to some cases of erectile dysfunction.
7. Substance abuse
Substance abuse such as smoking, alcohol, marijuana or other drugs often causes erectile dysfunction.
