At what age do boys typically start experiencing nocturnal emissions?

Generally, boys begin to experience nocturnal emissions during puberty, typically between the ages of 11 and 13. A detailed analysis is as follows:

Most boys start experiencing nocturnal emissions between ages 11 and 13, which is a normal sign of pubertal development. However, some boys may experience nocturnal emissions as early as 8 or 9 years old due to individual differences in physical development, while others may not start until 14 or 15 years old, or even as late as age 18.

During puberty, a boy's reproductive system begins producing sperm and semen. As semen accumulates to a certain level, ejaculation may occur during sleep—this is known as a nocturnal emission. Nocturnal emissions not only indicate maturation of the male reproductive system but are also accompanied by other physiological changes associated with puberty, such as height growth, muscle development, and deepening of the voice.

Psychologically, boys may feel confused, embarrassed, or anxious about nocturnal emissions. Parents and teachers should provide appropriate guidance and education to help them understand this normal physiological phenomenon.

Nocturnal emissions are a normal part of puberty; however, if a boy experiences excessively frequent emissions (such as one every night) or if they are accompanied by symptoms such as dizziness, tinnitus, or soreness and weakness in the lower back and knees, he should seek medical attention promptly for evaluation.

During puberty, boys should maintain healthy lifestyle habits, including balanced nutrition, moderate exercise, and regular sleep patterns, to support overall physical and mental health.
