What Causes Erectile Dysfunction?
Though the rate of men experiencing erectile dysfunction increases with age, ED can affect men of every age. Like your favorite muscle car, male arousal depends on many systems operating together: the brain, nervous system, cardiovascular system, hormones, and even emotions all play a role in stimulating and exciting men in sexual situations. ED can happen if blood flow to the penis is limited as a result of, for example, nerve damage. Stress, hormonal changes, relationship problems, and mental health issues may also cause ED. Since there are so many contributing factors to ED, the condition can and often does affect every man at one time or another.
