Erectile dysfunction occurs when a man is not able to reach an erection and last long enough to have a complete sexual intercourse. Problems with erection that happen from time to time are not considered erectile dysfunction. We call it a disorder when 25% or more of the attempts to have an intercourse fail.
The causes of erectile dysfunction may be either physical or mental in nature. The list of the first ones includes all kinds of diseases (e.g., diabetes, atherosclerosis, hypertension, prostate diseases), spinal cord injuries, multiple sclerosis, neurological disorders, hormonal changes, damages made to the corpus cavernosum of the penis and the use of stimulants.
Erectile dysfunction may also be due to a number of psychological factors, such as chronic stress, anxiety, fatigue, lack of sleep, fear of women, depression or low self-esteem.
There are a few types of erectile dysfunction. The most serious one is when a man is completely unable to have an erection. Penis is flaccid regardless of the level of sexual arousal as well as the length and intensity of stimulation.
The described type of problems also includes incomplete erection and erection with short duration. In the first case, a man is not able to go through all the stages required for reaching an erection, which means that the penis is not hard enough for sexual intercourse.
However, short erection means that a man reaches full erection, but it gets weaker before having an orgasm, which prevents ejaculation.
