There are two centers responsible for controlling male erections: one is the higher brain center, usually the main function is to inhibit erections, and sexual demand and sexual stimulation when the state of excitement, promote erections; and a lower center, located in the spinal cord, mainly promote the formation of erections. During sleep and near waking up in the morning, the corresponding brain is in a state of inhibition, that is, the lower center loses the inhibition of the brain, and it will form an excitation phenomenon that promotes penile erection, which forms the phenomenon of male erection throughout sleep and in the morning. At the same time, there is morning erection that indicates that the sexual function of the human body is in a relatively normal and good state, which is also a good thing.
