Sperm loss in boys does not usually affect their height. Sperm loss in boys is a manifestation of the maturation of the reproductive organs in the body, and the first sperm loss in boys occurs when they are 12-13 years old. If the seminal emission only happens once in a while, it will not affect the patient’s height, because seminal emission is a normal physiological phenomenon. The time of seminal emission is usually in puberty, which is instead the peak of growth. It is recommended to guide the boy’s mind during this period, not to think that seminal emission is an embarrassing thing, but to tell him that seminal emission is a normal physiological phenomenon and not a disease.
