In addition to changes in height, weight, and other factors that are easily observed by parents, boys who are in adolescence should also be aware of their own maturity and development.
Boys generally begin to grow their testicles around the age of 12, and their testicular volume approaches that of adults around the age of 18. Testicular development and increased volume are important reflections of adolescent growth and development. Sometimes, when one touches the testicles with their hands, it feels like they will slowly grow.
At the same time, the boy developed ejaculation after the age of 13, and the interstitial cells of the testicles began to secrete testosterone, leading to sexual dreams and an erection of the penis. As the concentration of its hormones in the plasma continues to increase, the reproductive organs further develop and mature, the voice becomes thicker, the laryngeal nodules protrude, and secondary sexual features such as dense whiskers and long axillary and pubic hair appear.
Regularly observing the external genitalia, it is found that the color of the scrotum becomes darker and larger. Generally, after the age of 9 to 12, the scrotum begins to become larger, accompanied by redness and changes in skin quality.
After the age of 12 to 15, the length and circumference of the penis increase, but the length of the circumference increase slows down and the penis becomes thinner. After the age of 15-18, the penis and scrotum further develop and enlarge, with a dark color and thick circumference of the penis. The hair of the penis extends forward, detached from the foreskin covering of the penis, and completely or mostly exposed outside the foreskin, approaching the adult type.
The pubic hair begins to grow from around 12 years old during puberty, gradually becoming dense and black, with a dense distribution. The pubic hair is also influenced by male hormones produced by the testes and adrenal glands. As the sexual organs mature, the secretion of male hormones increases. After about 18 years old, the pubic hair of boys is distributed in a pointed triangular shape, with the tip usually reaching the lower abdomen, similar to the typical pubic hair of adult males.
During the process of male adolescent sexual development, do not panic when encountering the above situations. If there is no physical discomfort, it can be considered normal development.
