the discharge of semen, usually during sleep. It is usually accompanied by erotic dreams, which may not be remembered after deep sleep. The first pollutions are one of the signs of sexual maturity and occur at the age of 14 or 15. An adult male may experience pollutions after prolonged sexual restraint. The age when pollutions begin and their subsequent frequency depend on the individual’s constitution, temperament, general state of health, way of life, and direction of interests.
