Question by Jim:

Hello. I am Jim, 45.

I have Multiply Sclerosis, and as many men with MS I have male impotence as well.

Still I have nocturnal erections – I wake up with a very firm penis.

But it disappears quickly and during the day I can’t achieve an erection again.

I tried Viagra, Cialis and Levitra.

Viagra helps, but not the way I want it to. Cialis and Levitra don’t work for me at all.

So the question is – why I have an erection when I sleep and can’t have it while awake?

Answer:

Hello, Jim. You are right – Multiply Sclerosis affects nerves and men with MS are usually experiencing ED too. The nature of nocturnal erections is not completely clear to medics. There is a theory that during sleep our brain sends certain signals to nerves and some of them cause erection. Other theory states that during sleep men can experience sexual arising dreams which in turn causes an erection. Third theory involves our bladder and states that during night it gets full and causes pressure to prostate. Under-pressure prostate causes stimulation to certain nerves and causes an erection.

The mechanism of the erection is the following:

Brain sends signals to certain nerves in penile area, causing certain chemicals to be released. These chemicals in turn make muscles in penile area relax, which in turn allows blood to flow the penis and cause an erection. The erection disappears when other chemicals called PDE5 are released. They cause penis muscles to constrict again and blood leaves the penis. Viagra and other impotence pills called PDE5 inhibitors work by blocking second type of chemicals.

There are many other ways how to fix impotence. You can try some classical treatments or natural ED remedies. And don’t forget to consult your physician!

My best wishes.
