Whenever we sleep, we cycle through 5 distinct phases. The fifth phase is called rapid eye movement (or REM) sleep. This is the period during our sleep when we dream. During REM sleep, unless you are having a very scary dream, both men and women will have genital arousal (an erection for men, increased vaginal lubrication or clitoral engorgement for women). This arousal often outlasts the REM stages, often lasting between 30-45 minutes. Morning wood is simply an erection resulting from the last REM sleep stage of the night. You are more likely to experience morning wood if you awake naturally, rather than by an alarm clock, which may interrupt your slumber during one of the other four sleep phases when your erection has worn off.

I took a women's study class at the university. The professor said that it is because guys have a lot of hormones running through their body when they sleep. This will explain the erection when he first wakes up in the morning.

G'Day mate
our body is a biological clock
during night the body cools so it goes in to sleeps (blood is drawn to the heart, away from other organs so the other organs can rest)
during early morning the body warms up (the body is flushed with blood ie the blood is forced to all parts of the body) hence the sleep breaks and you wake up
so when this happens the penis is also filled with blood so it is gets erect.
penis gets erect when more blood flows through it thats the science behind erection.

Men often get erections when they have to urinate badly (like after having slept all night).
