Depression. The profound sadness, emptiness, and hopelessness that characterize depression may also cause ED among younger men. “The biggest effect of depression is on a man’s desire for sexual relations, or libido,” says Drogo Montague, MD, director of the Center for Genitourinary Reconstruction in the Glickman Urological and Kidney Institute at the Cleveland Clinic. “To some extent, depression can affect a man’s ability to maintain an erection. It can be a chicken-and-egg situation. However, reduced libido is a common indicator of depression.”
These specific chemicals are found in erectile dysfunction medications such as Viagra and Cialis."The chemicals that cause the outflow are called phosphodiesterases," says Reitano. "To give you a stronger erection, erectile dysfunction medications (PDE-5 inhibitors) block or inhibit the phosphodiesterases, which enables the blood vessels in the penis to stay open and receive more blood, creating a firmer and longer lasting erection. This is why the drugs are called phosphodiesterase inhibitors (PDE-5 inhibitors for short)."
Like going bald, ED becomes more common as men age. According to the National Institutes of Health, about 5% of all 40-year-old men have ED and that number rises with age. Between 15% and 25% of 65-year-old men have ED. This is one of the reasons you see so many ED drug commercials during televised sporting events, Fox News programs, and other shows that typically attract men over 50 (just kidding, Fox).
What causes a man not to be erect?
Injury to the nerves and arteries near the penis can lead to erectile dysfunction. According to the National Institutes of Diabetes and Digestive and Kidney Diseases, surgeries for prostate and bladder cancer can injure penile nerves and arteries, although it doesn't always happen. Spinal cord injuries can affect the ability to achieve and maintain an erection, as can injuries to the penis, prostate, bladder and pelvis.
Erectile dysfunction in older men. Because erections primarily involve the blood vessels, it is not surprising that the most common causes in older men are conditions that block blood flow to the penis, such as atherosclerosis or diabetes. Another vascular cause may be a faulty vein, which lets blood drain too quickly from the penis. Other physical disorders, as well as hormonal imbalances and certain operations, may also result in erectile dysfunction.

As the nervous system of autonomic response, the erection can result in different stimuli that include the sexual arousal and stimulation which is not even under the control of the conscious mind. The absence of the nocturnal erection is also used commonly for distinguishing between the psychological and physical cause of impotence and erectile dysfunction.
Ask about transurethral pharmacotherapy. Your doctor may suggest you try this treatment, which involves placing a suppository into the urethra. The suppository contains alprostadil, which is then absorbed into the blood stream, relaxing blood vessels and improving blood flow into the penis. This treatment is thought to be less effective than the vacuum devices, or injection therapy.
