Andropause and Erectile Dysfunction

One of the signature symptoms of Andropause is erectile dysfunction (ED). An embarrassing, nerve-wrecking experience, ED is when a male cannot perform for his female partner. In layman’s terms, it is the inability to have an erect penis during sexual activity.

It is the primary issue amongst men in regards to their sex lives. Let’s become acquainted with how a full erection works and why this condition exists.

Men under the influence of Andropause have erectile dysfunction no matter what’s on their mind. Thinking of a nude Playboy centerfold model would likely induce pleasant and sexual thoughts into a man. Sexual thoughts, however detailed or brief they may be, are produced in the brain. After all, the brain is responsible for thinking. These sexual thoughts directly spark nerve signals down through the spinal cord and into the muscles of the penis. These nerves send a flow of blood running through the arteries in the penis while it is in a relaxed state, building pressure.

A man without Andropause can have a constant, steady flow of blood flowing to his penis arteries in a good amount. The more blood that flows down there, the harder and longer your erection will be! When sexual thoughts creep out of your mind and you’re focused on another activity, your penis returns to its relaxed state. We can guess Andropause sufferers are going to have to do something

Do erectile dysfunction drugs causes NAION ?

On July 8, 2005 the FDA ordered warnings be put on the package insert labels of Viagra, Cialis, and Levitra to the effect that some users of these impotence drugs -- or erectile dysfunction (ED) drugs -- have developed NAION, a form of blindness. At the same time, however, the FDA stated that it is impossible at present to know if NAION is a side effect of these ED drugs, or an unrelated medical condition.

NAION is considered one of the most common causes of sudden vision loss in older people, with anywhere from 1,000 to 6,000 cases a year, also NAION is one of the most common causes of unexpected or sudden vision loss in older Americans. So question arises here is what exactly is the NAION? and is there a risk from taking erectile dysfunction drugs?

What is NAION and what is happening inside the body to cause damage to  sight?

NAION is an acronym for Nonarteritic Anterior Ischemic Optic Neuropathy. Well, basically, the optic nerve is a nerve that connects the eye to the brain. That's how we see.

The optic nerve has tiny blood vessels that perfuse it and that's how it gets its blood supply and oxygen for it to function properly.The condition generally starts in one eye and can cause complete blindness if both eyes are affected. Those who have poor eyesight appear to have the highest chances for developing NAION.

Is there a risk from taking erectile dysfunction drugs?

It is possible that in certain individuals the drugs could potentially to  this. For example, one theoretical mechanism -- which hasn't been proven, but it is a possibility -- is we know these drugs in some patients lower the blood pressure overall in the body. And it's possible that as the drug lowers the blood pressure, the blood flow through the tiny blood vessels in the optic nerve may be temporarily diminished. And during that time, the optic nerve may suffer damage. Now, again, this is not a definite mechanism, it's just a proposed possible mechanism for why this may occur.
