The scientific name for morning erection is nocturnal penile tumescence. It is actually a sign of good health and is very normal. It points to having a health level of the male hormone testosterone. Generally all males exhibit a degree of erection in the morning, even small boys and it has even been demonstrated in male foetus in the uterus using ultrasounds.
Funny fact: In America they are referred to as ‘Having Morning wood!’
I would be worried if I wasn’t getting morning erections (erect penis in the morning). This is a sign of good health and that your body functions normally, much like yawning when you are hungry or tired.
