Morning erections, colloquially referred to as "morning wood" and scientifically defined as nocturnal penile tumescence (NPT) are a healthy and normal physiological response that most men experience. Normally it happens when they are asleep. Men begin having them in early childhood and they continue throughout adult life. They appear during REM (Rapid Eye Movement) sleep, the stage of sleep where dreaming occurs.
However, these involuntary erections have nothing to do with dreams or sexual excitement. They occur when neurological stimulators cause blood to flow into the penis. This ensures that oxygen is properly delivered to the penis and helps keep penile tissue healthy.
Men don't normally notice these erections, but may occasionally encounter them upon waking. On average a healthy male will have between three and five erections in a full night sleep, with each erection lasting between 25 -35 minutes. Men who are unable to have an erection because of a psychological problem still have erections during the night.
Many men say that "morning" or nocturnal erections are noticeably harder than those during the day. This is normal, and a natural result of nocturnal erections.

Normally, male testorene tends to increase to its highest level early in the morning after a restful sleep.
Thanks for sharing your informative write up. Morning erections attracted the interest of researchers as a tool to rule out physical causes of erectile dysfunction. If a man cannot get an erection to his satisfaction during sexual activities, one of the first things a doctor will determine is whether or not he is getting full erections during the night and in the morning.
This is a nice article. Good insights. Thanks for sharing your informative write up. The frequency of morning erections predicted the development of complete erectile dysfunction, with an approximate 2.5-fold risk among those with less than 1 morning erection per week compared with 2 to 3 morning erections per week.
