Before having a regular sexual life, the physiological phenomenon of seminal emission in males after puberty is not contradictory to growth and development, and it does not affect growth and development after seminal emission. The rapid growth of height from puberty is a physiological phenomenon that occurs after secondary sexual characteristics. Whether or not seminal emission occurs, there is no need to worry too much. Even if seminal emission occurs, it will not have an obvious effect on height, weight and other developmental states, so there is no need to worry too much. If seminal emission occurs frequently or even several times a night, it is pathological and requires detailed examination to clarify the cause and then targeted treatment, even if it is pathological, it will not affect height.
