Sexual Development Issues in Adolescents: A Guide

Sexual development issues

Hello, doctor.
I am currently 17 years old, weighing 105 pounds and standing 166 cm tall.
My pubic hair has developed normally, but my penis is less than 4 cm when not erect, and when fully erect, it measures about 14 cm.
Additionally, I have very little facial and underarm hair; I shave my beard roughly once a month, while many of my classmates seem to need to groom theirs weekly.
I'm uncertain if there is an issue.
I have had a habit of masturbation since sixth grade, typically doing it once a day.
I've researched a lot, but I'm not sure if my penis appears short.
I would like to ask if the short size when not erect is related to my weight.
Furthermore, I am currently exercising regularly and controlling my diet.
If I lose weight, will my penis size normalize? Also, I have a condition of phimosis and wonder if it is related to obesity.
I hope the doctor can provide some answers.

Dr. Hong Yuanbin reply Internal Medicine

Hello, based on your description, it seems that the appearance of a shorter penis may be due to excess fat around the base, which can obscure the penis.
Additionally, being overweight can affect the secretion of sex hormones, which may also impact physical development.
Therefore, it is advisable to manage your weight through regular exercise and dietary control.
Thank you for your inquiry.

More Info

Understanding sexual development during adolescence is a complex topic that encompasses physical, emotional, and psychological changes. At 17 years old, you are in a critical stage of development where many factors can influence your sexual health and self-perception. Let's address your concerns systematically.

1. Physical Development and Concerns
From your description, it appears that you are experiencing some typical variations in physical development. The size of the penis, both when flaccid and erect, can vary significantly among individuals. An erect penis size of 14 cm (approximately 5.5 inches) is within the average range. However, the flaccid size can be influenced by various factors, including genetics, body weight, and even temperature.

Regarding your concern about your weight (105 kg) and height (166 cm), it is important to recognize that obesity can affect hormonal balance and overall health, which may indirectly influence sexual development. Excess body fat can lead to higher levels of estrogen and lower levels of testosterone, which can affect secondary sexual characteristics such as body hair growth and possibly even penis size. Regular exercise and a balanced diet, as you mentioned you are pursuing, can help improve your overall health and may positively influence your hormonal balance.

2. Puberty and Hormonal Changes
During puberty, the body undergoes significant hormonal changes that drive sexual development. Testosterone plays a crucial role in the development of male secondary sexual characteristics, including body hair, muscle mass, and changes in the penis and testicles. The amount of body hair, such as facial and underarm hair, can vary widely among individuals and is influenced by genetics and hormonal levels.

If you are concerned about your development, it may be beneficial to consult with a healthcare provider who can assess your growth patterns and hormonal levels. They may recommend blood tests to check your testosterone levels and other relevant hormones.

3. Masturbation and Sexual Health
Masturbation is a normal part of sexual development and is common among adolescents. Engaging in this behavior does not inherently cause harm, but it is essential to maintain a healthy perspective on it. If you find that it interferes with your daily life or responsibilities, it may be worth discussing with a healthcare professional.

4. Foreskin and Health Concerns
You mentioned having a long foreskin (phimosis). This condition can occur in some individuals and may not necessarily be related to body weight. If the foreskin is causing discomfort or hygiene issues, it is advisable to consult a healthcare provider. They can provide guidance on proper care and whether any medical intervention is necessary.

5. Emotional and Psychological Aspects
Adolescence is also a time of emotional and psychological changes. Feelings of insecurity about your body are common, especially during this developmental stage. It is crucial to foster a positive body image and understand that everyone develops at their own pace. Engaging in open conversations with trusted friends or family members about your feelings can be beneficial.

Conclusion
In summary, your concerns about sexual development are valid and reflect common experiences during adolescence. Maintaining a healthy lifestyle through regular exercise and balanced nutrition is essential. If you have ongoing concerns about your physical development, hormonal levels, or emotional well-being, seeking advice from a healthcare professional can provide clarity and support. Remember, puberty is a unique journey for everyone, and it is okay to seek help when needed.
