Pediatric Penile Concerns: When to Seek Medical Advice - Pediatrics

Penile issues


Hello, Doctor.
I am Chen from Taichung.
I often feel troubled by my penis size; it is only 3 cm when flaccid and 5-6 cm when erect.
I always feel that this is abnormal! Is this related to my weight? (I weigh 43 kg) Or is it due to my constitution? Is it related to my developmental stage? My brother, who is three years older than me, has a flaccid size of 6 cm and an erect size of 9-10 cm.
I would like to ask the doctor if I need to seek medical attention.

Dr. Lin Yishou reply Pediatrics

Hello! Thank you for reaching out with your concerns regarding penile development. It's understandable to feel worried about these issues, especially during the developmental years. Let's break down your concerns and provide some guidance on when to seek medical advice.

First, it's important to recognize that penile size can vary significantly among individuals, especially during childhood and adolescence. Factors such as genetics, hormonal levels, and overall health can all play a role in development. At your age, it's common for boys to experience a wide range of sizes, and many boys may not reach their full adult size until they are older, often during puberty.

Regarding your specific measurements, a penis size of 3 cm when flaccid and 5-6 cm when erect is on the smaller side compared to average sizes reported in studies. However, it's crucial to remember that size does not necessarily correlate with function or sexual health. Many boys and men with smaller sizes lead perfectly normal sexual lives.

You mentioned your weight of 43 kg (approximately 95 lbs). While body weight can influence overall health and development, it is not a direct determinant of penile size. It's more important to focus on maintaining a healthy lifestyle, which includes a balanced diet and regular physical activity.

As for your concerns about your brother's size, it's essential to understand that siblings can develop at different rates. Puberty can start at different ages, and some boys may experience growth spurts earlier or later than others. Your brother may have started puberty earlier, which could explain the difference in size.

When to Seek Medical Advice:
1. Age and Development: If you are concerned about your development, particularly if you are nearing the age of 14 and have not started to show signs of puberty (such as testicular enlargement, pubic hair growth, or penile growth), it may be a good idea to consult a healthcare professional.
2. Physical Symptoms: If you experience any pain, discomfort, or other unusual symptoms related to your penis or testicles, you should seek medical advice regardless of size.

3. Psychological Impact: If your concerns about size are causing significant distress or affecting your self-esteem, talking to a healthcare provider or a mental health professional can be beneficial. They can provide support and help you navigate these feelings.

4. Family History: If there is a family history of hormonal issues or developmental concerns, it may be worth discussing this with a doctor.

In summary, while your concerns about penile size are valid, it's essential to consider the broader context of your overall health and development. If you feel uncertain or anxious about your situation, don't hesitate to reach out to a pediatrician or an endocrinologist specializing in adolescent health. They can provide a thorough evaluation and reassurance, as well as address any underlying issues that may need attention.

Remember, every individual develops at their own pace, and there is a wide range of what is considered normal. Focus on being healthy and active, and seek help if you feel it is necessary. Take care!
