When Does the Development of Reproductive Organs Occur?

The development of reproductive organs is very slow in childhood and is in a primitive state. Upon entering puberty, under the influence of endocrine, internal and external reproductive organs rapidly develop. Compared with other systems in the body, the reproductive system matures in a relatively short period of time, showing significant gender characteristics. Sexual development includes morphological development, functional development, and secondary sexual characteristics of reproductive organs. Males generally start at around 12-13 years old. The penis of males generally matures between 18 and 20 years old. The specific development time varies from person to person and there is no specific time. The development of many male penises is affected by various factors, mainly related to genetic factors, nutritional status, and obesity factors. As long as males ensure good nutritional supply during puberty, exercise regularly, and maintain a strong physique, their reproductive organs can develop well, and their penis will be relatively large. In addition, obesity may lead to a small penis, so attention must be paid. The normal length of the male penis is 4-11 cm when not erect, and the diameter is 1.5-4.0 cm. When the penis is erect, it is normal for it to be 8-18 cm long. Everyone's physique is different, so the size of the penis will also vary. The size of the penis within the normal range does not affect sexual activity. The penis during growth and development may be relatively small, and an accurate measurement can be made at the hospital. If the penis is relatively small, do not be self-conscious.
