Nocturnal penile tumescence
From Wikipedia, the free encyclopedia
Jump to: navigation, search
In anatomy and physiology, nocturnal penile tumescence is the spontaneous occurrence of a penile erection during sleep in the absence of any sexual stimulation. All men who are physically able to achieve erection do so during sleep, typically several times in a night[1]. It typically happens during REM sleep and it is not uncommon for an erection to be present when a man wakes up — such an erection is colloquially referred to as morning wood in North America, and as morning glory in the United Kingdom (though in some areas of the U.K. the adjective piss-proud is often used instead).
The existence and predictability of nocturnal tumescence is used by sexual health practitioners to ascertain whether a given case of erectile dysfunction (E.D.) is psychological or physiological in origin. A patient presenting with E.D. is fitted with an elastic device to wear around his penis during sleep; the device detects changes in girth and relays the information to a computer for later analysis. If nocturnal tumescence is detected, then the E.D. is presumed to be due to a psychosomatic illness such as sexual anxiety; if not, then it is presumed to be due to a physiological cause.

A full bladder will fill up the urethra, which is a tube running from the bladder through the centre of the penis, through which urine (and semen) are expelled. The irony is, it's hard to relax it to let yourself pee through it. So, the kidneys, working to filter the blood, are what fills the bladder overnight.

it's called "morning wood"
and it's because when you sleep you get 5-8 erections
to keep the blood flowing and to keep it in shape
hope this helped ;)

Probably because you need to pee. Does the erection go away after you piss?

Dude All men wake up that way because you may have had a dream that was frisky. When my son was born and he would wake up with a hard on and that is because it was a tee tee hard on and that meant that I better close the diaper as fast as I can. His daddy woke up the same way so that is the answer to your question. I hope it was helpful for you.

Succubi routinely come to men in their sleep and have sexual intercourse with them, so as to collect their sperm and create more demonic babies. Waking up with an erection is a tell-tale sign of a visitation by a succubus. Congratulations on your impending fatherhood!

they're dreaming of something rude, or blood circulation, saw a guy crack a fat on stage during a hypnotist's act.

because between 7-9am is the time when your body is the most sensitive to touch, noises and therefore becomes aroused easily.

This is when testoterone levels are at the highest.

It's normally because of a nice dream or sometimes due to the blood flow.
