The Biology Of...

Most healthy men wake up in the morning with an erection. The slang term for this is 'Morning Wood'. This is normal and it's fairly common. Men have several erections a night as part of their sleep cycle. Many times they wake up and find they are still erect.

Man's penis becomes erect in response to sexual arousal, excitement, and deep relaxation such as what's experienced in deep dreaming sleep. An erection is caused by a rush of blood to the penis. A man's penis, especially a young man's penis, can also become erect without any kind of arousing stimulation and this is called a 'spontaneous erection'.
