Seminal emission at night in bed is a process that all men must have. Men generally start to develop sexually from around the age of 12, and generally by the age of 14 or so sexual development gradually starts to mature and sperm loss begins to occur. Because the testicles are constantly producing sperm, the sperm produced by the testicles is stored in the seminal vesicles through the epididymis. When the semen is stored in the seminal vesicles to a certain amount, the human body is sexually excited due to the secretion of androgens and is exposed to sexual texts and pictures, so that the penis may become erect at night and the glans is stimulated, which leads to a sexual response and the phenomenon of seminal emission. So male seminal emission does not need to do special treatment, male seminal emission is generally 3-4 times a month is normal.
