Causes of erectile dysfunction are organic, functional and psychological; in most cases there is a combination of causes. If the patient never had erection erectile dysfunction is probably organic. If the patient has erections, even if rare, it is possible the cause to be psychological such as negative thoughts, expectations or misinterpretations. According to specialists, psychological mechanisms are involved in over 60% of sexual dysfunction. Performance anxiety associated with autonomic nervous system imbalance can affect sexual behavior.
Erectile dysfunction is influenced by psychological factors, neurological, vascular, hormonal, and local. Most commonly, erectile dysfunction is caused by: hypertension, high cholesterol, diabetes, atherosclerosis, spinal injuries, multiple sclerosis, stroke, Alzheimer’s disease, hyperthyroidism, hypothyroidism, hypogonadism, surgery, trauma, drugs (antidepressants, diuretics, antihypertensive, antiepileptic, chemotherapeutic agents), smoking, obesity, alcohol abuse and drug abuse.
Researchers have found that men who have sex less than one time a week have a higher risk of developing, over time, erectile dysfunction, compared with those who have sexual intercourse at weekly. The most cases of erectile dysfunction were found in men who have had sex very rarely. Those who have not been affected by erectile dysfunction reported having sex at least three times a week. So, regular sex can prevent the early development of erectile dysfunction. Also regular sexual activity plays an important role in maintaining normal erectile function in older men.
A regular sexual life increases the levels of sex hormone which can prolong the youth and keep the heath healthy. Also, sexual activity stimulates the production of vitamin D in the body and the love hormone oxytocin, which helps brain to function well. If you have sex more than three times a week it reduces the risk of heart attack, especially in men. Older men who have sex are less likely to develop prostate cancer. Sex is linked to libido and a low libido can determine erectile dysfunction, but there are ways to increase sexual desire, especially through food or natural supplements: coffee stimulates libido, while peanuts, brown rice and avocado boost sex drive.
Normal erectile function cannot be maintained without an optimal blood flow to the penile tissue. All the methods that blood flow to the penis can prevent erectile dysfunction, but also contribute to the recovery of patients after prostate cancer treatment. The improvement of blood circulation to the penis can be done by several methods such as the use of natural pills and supplements, keeping a healthy body by eating many fresh foods, doing regular exercise, quitting smoking and reducing the amount of alcohol.
