Waking up with an erection, commonly known as morning wood or nocturnal penile tumescence, is a normal physiological response in males. It typically occurs during the REM (rapid eye movement) stage of sleep, when the body experiences increased blood flow and hormonal changes. This phenomenon is a sign of healthy erectile function and does not necessarily indicate sexual arousal. It can happen multiple times throughout the night and is common in men of all ages.
