Patient's question:
I recently don't know what's going on, my lower body is very uncomfortable, and I'm not getting morning erections anymore. What are the reasons for penile erection during sleep?Doctor's answer:
Erections of the male penis after sleep is a normal physiological phenomenon. During each night's sleep, every man's penis goes through the physiological process of erection—flaccidity—erection—flaccidity with the alternation of rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep. This is known as nocturnal penile tumescence in medicine and is a normal physiological process for healthy men. Generally, young men experience about 4-6 erections per night, each lasting 20-30 minutes, with a total duration of up to two and a half hours. As age increases, the frequency and duration of penile erections gradually decrease. This nocturnal penile erection is a spontaneous physiological phenomenon during sleep and is not subject to human subjective will. Therefore, there is no need to be anxious, nor should medication be used blindly to control it.
