The second article on size differences?
I previously sent a message and I'm not sure if you remember.
You asked me some questions.
I graduated from elementary school at a height of 158 cm, and I have grown to 167 cm now.
I have developed all the necessary secondary sexual characteristics.
My voice doesn't seem very deep, and my shoulders are smaller than those of most boys.
My upper body is longer than my lower body.
Does this indicate that I have gone through puberty or not? I remember my measurements in elementary school were about the same, but I didn't measure them back then, so I don't know how many centimeters they were.
Currently, when not erect, my penis is less than 4 cm, and when erect, it is 12 cm, but it is not thick.
Does this mean I have developed, or could it be related to some genetic factors? I apologize for bothering you with this.

Mild Depression: It's good to see you again, and I can sense your continued concern.
Here, I have some information for you: According to statistics from Tri-Service General Hospital, the average length from the base of the penis to the urethral opening in young males is approximately 7.1 cm when flaccid and about 13.5 cm when erect.
As for what is considered a significantly short penis, it is generally accepted that a length of less than 4 cm when flaccid and less than 7 cm when erect may warrant a consultation with a urologist.
Infertility and small testicular size should be evaluated through endocrine and chromosomal testing.
Do you understand? A length of 12 cm is still considered normal.
Urology Department Chief, Hsu Wei-Kai, responding on behalf of the Taitung Hospital of the Department of Health, is concerned about you.

Understanding male development during puberty can be a complex topic, as it involves various physical changes that occur at different rates for each individual. Based on the information you've provided, it seems like you have several concerns regarding your growth patterns, physical development, and overall puberty progression.
Firstly, it's important to recognize that puberty is a highly individualized process. For boys, puberty typically begins between the ages of 9 and 14 and can last until the late teens. During this time, various physical changes occur, including growth spurts, the development of secondary sexual characteristics (such as body hair, voice changes, and genital growth), and changes in body composition.
From your description, you mentioned that you graduated elementary school at a height of 158 cm and are currently 167 cm. This indicates that you have experienced some growth, which is a positive sign. The fact that you have developed body hair and have noticed changes in your voice suggests that you are indeed going through puberty. However, you also express concerns about your height and the size of your genitalia.
Regarding height, it's essential to understand that growth patterns can vary significantly. Many boys experience a growth spurt during early to mid-puberty, followed by a slower rate of growth as they approach the end of puberty. The average height for adult males varies by population, but genetics plays a crucial role in determining your final height. If your parents are of average height, it is likely that you will also fall within that range. Additionally, the growth plates in your bones will eventually close, which will halt further height increase. A bone age assessment can help determine how much growth potential you have left.
As for your concerns about genital size, it's important to note that there is a wide range of normal sizes for male genitalia. The average erect penis size is typically around 12 to 16 cm, but variations are common. If you are still in the midst of puberty, there is a possibility that you may continue to grow in this area as well. Factors such as genetics, hormonal levels, and overall health can influence this development.
You also mentioned that your shoulders are smaller than average and that your upper body is longer than your lower body. These proportions can be typical during certain stages of growth, especially if you are still developing. As you continue to grow, your body will likely undergo changes that may balance out these proportions.
In summary, it seems that you are experiencing normal puberty-related changes, albeit at your own pace. If you have concerns about your development, it may be beneficial to consult with a healthcare provider who specializes in adolescent medicine or endocrinology. They can provide personalized insights based on your growth patterns, family history, and any physical examinations that may be necessary.
In conclusion, puberty is a unique journey for everyone, and while it can be filled with uncertainties, understanding the typical patterns of growth and development can help alleviate some concerns. Remember that patience is key, and many changes may still occur as you continue through your teenage years.
