    Sometimes some things cannot be fully understood through real experience. Just like when do boys have frequent nocturnal emissions and at what ages do men have frequent nocturnal emissions. So, what’s the answer?

    What is nocturnal emission? Frequent nocturnal emission is the ejaculation of men when they are not active during sexual intercourse. It is a common normal physiological condition among teenagers and children. About 80% of single young people often have this phenomenon. Frequent nocturnal emissions are divided into physiological frequent nocturnal emissions and pathological nocturnal emissions. Physiological frequent nocturnal emissions refers to the ejaculation of single young people or men who have separated after marriage and have not had sex. Frequent nocturnal emissions usually occur once every 2 weeks or more and do not cause any discomfort to the human body. The erection function of the genitals is normal, and nocturnal emissions can occur without dreams or with dreams. With the development of secondary sexual characteristics, the concentration of steroid hormones in blood cells reaches human levels and is converted into male sperm, resulting in frequent nocturnal emissions.

    So when do boys start to have frequent nocturnal emissions? When boys reach around 16 years old, they reach sexual maturity. If there is normal sex at this time, it will cause the man to ejaculate. However, if a man ejaculates suddenly without carrying out normal daily life, it is called frequent nocturnal emission. Generally speaking, a man's ejaculation while sleeping is called a nocturnal emission; while a man's ejaculation while he is awake is called a nocturnal emission.

    As for the age at which men will have frequent nocturnal emissions, frequent nocturnal emissions rarely occur in boys under the age of 12. The incidence of frequent nocturnal emissions in boys by the age of 14 is about 25%. The incidence rate is higher among male teenagers in big cities and with better family economic conditions. It is about 55% at the age of 16, 70% at the age of 18, and 75% to 80% at the age of 20. If the child is 11 years old, it is normal to have frequent nocturnal emissions!

    As the age increases, the frequency of frequent nocturnal emissions will gradually decrease. Boys generally have less frequent nocturnal emissions or no frequent nocturnal emissions after the age of 40. Therefore, if the married life is irregular, frequent nocturnal emissions may occur at the age of 40. But if the couple's life is very regular, there will be abnormalities.
