Questions regarding one's own reproductive organs?


I would like to ask, I am currently in the first year of high school, but my genitalia is almost similar to that of a child.
However, I have developed pubic hair, armpit hair, and facial hair.
I'm unsure about how long male development continues, and I am a bit worried.

Hei Hei, 10~19 year old female. Ask Date: 2016/03/21

Dr. Chen Wenming reply Urology


Having pubic hair should not be a cause for concern.

It's completely normal to have concerns about your development during puberty, especially as a high school freshman. Puberty is a complex process that varies significantly from person to person, and it's important to remember that everyone develops at their own pace.
Typically, puberty in boys begins between the ages of 9 and 14, and it can last until the late teens. The first signs of puberty usually include the growth of testicles and the scrotum, followed by the development of pubic hair, underarm hair, and facial hair. You mentioned that you have developed pubic hair, underarm hair, and facial hair, which indicates that you are indeed experiencing some aspects of puberty.
However, the size and appearance of the penis can vary widely among individuals. Some boys may notice significant growth in their genitalia early in puberty, while others may experience this growth later on. It's also common for boys to feel self-conscious about their bodies during this time, especially when comparing themselves to peers.
In terms of the timeline for male puberty, it generally progresses through several stages:
1. Stage 1 (Prepubertal): This is the stage before any physical changes occur. The testicles and penis are small, and there is little to no pubic hair.

2. Stage 2 (Early Puberty): The testicles begin to enlarge, and pubic hair starts to appear. This stage can start as early as age 9.

3. Stage 3 (Mid-Puberty): The penis begins to grow in length and girth, and pubic hair becomes coarser and darker. This stage typically occurs between ages 11 and 14.

4. Stage 4 (Late Puberty): The penis continues to grow, and the scrotum darkens. Facial hair becomes more prominent, and the voice begins to deepen. This stage usually occurs between ages 13 and 16.

5. Stage 5 (Post-Puberty): This is when the male body reaches its adult form, and growth in height and genital size stabilizes. This stage can occur anywhere from ages 16 to 20.

It's important to note that while these stages provide a general guideline, individual experiences can vary widely. Some boys may complete puberty earlier, while others may take longer. If you are concerned about your development, it might be helpful to speak with a healthcare professional who can provide personalized advice and reassurance.

Additionally, if you are experiencing anxiety or distress about your development, consider talking to a trusted adult or counselor. They can help you navigate these feelings and provide support as you go through this significant life stage. Remember, puberty is a natural process, and it's okay to have questions and concerns. You're not alone in this journey, and many others share similar experiences.
