In recent years, the age and influencing factors of boys’ nocturnal emissions have become a hot topic among parents and teenagers. This article will combine the hot discussions on the Internet in the past 10 days to conduct a structured analysis of the relevant data on boys’ nocturnal emissions.
1. Age range of nocturnal emissions

According to medical research and clinical data, there are individual differences in the age of boys’ first nocturnal emissions, but they are mainly concentrated in the following ranges:
| age group | Proportion | Influencing factors |
|---|---|---|
| 10-12 years old | 15% | Early development and adequate nutrition |
| 13-15 years old | 65% | Most healthy boys |
| 16-18 years old | 18% | Late development, physical factors |

| genetic factors | Father's development time | high |
| nutritional status | protein intake | Middle to high |
| physical exercise | Exercise frequency and intensity | in |
| mental state | stress and emotions | in |
| environmental factors | contact time | low |
3. Physiological mechanism of nocturnal emissions
Nocturnal emissions are a sign of the maturity of the male reproductive system, and its physiological processes mainly include:
1.testicular development: The testicles begin to produce sperm and testosterone
2.seminal vesicle filling: Seminal vesicles and prostate secrete semen

5. Analysis of common misunderstandings
Based on recent social media discussions, the following common misunderstandings have been sorted out:
1."Nocturnal emissions affect height": There is no scientific basis. Height is mainly affected by genetics and nutrition.
2."The earlier a nocturnal emission occurs, the better": Development time varies from person to person. If it is too early, you need to pay attention to precocious puberty.
3."Nocturnal emissions require treatment": Normal physiological phenomenon unless accompanied by other symptoms
4."can be controlled by humans": A natural physiological process that should not be deliberately inhibited
