Penile issues


The penis measures 5 cm when not erect and 13 cm when erect.
Is there still potential for further development?

Dr. Fu Shizhang reply Urology


At your age, it is generally unlikely for further development to occur under normal circumstances.
Online consultations cannot replace an in-person examination and physical assessment by a physician.
If there are any health concerns, it is still advisable to seek medical attention at a healthcare facility.

Understanding penis growth and development during puberty is a common concern for many young men. The growth of the penis, like other aspects of physical development, is influenced by a variety of factors, including genetics, hormonal levels, and overall health.
During puberty, which typically begins between the ages of 9 and 14 and can last until the late teens, males experience significant changes in their bodies. This includes the growth of body hair, changes in voice, and the development of the reproductive organs. The penis usually begins to grow in length and girth during this time, often accompanied by increased frequency of erections, both spontaneous and in response to sexual arousal.

In your case, you mentioned that your penis measures 5 cm when flaccid and 13 cm when erect. It is important to note that penis size can vary widely among individuals, and there is a broad range of what is considered "normal." Research indicates that the average erect penis size is approximately 12 to 16 cm, so your size falls within this range.
As for whether you can expect further growth after puberty, it is generally accepted that most males will experience the majority of their penis growth during the early to mid-teen years. By the age of 18, many will have reached their final size, although some may continue to see minor changes into their early twenties. Factors such as genetics play a significant role in determining the final size of the penis. If your father or other male relatives have similar sizes, it is likely that you may have inherited this trait.

Regarding your concern about whether you can grow larger, it is unlikely that significant growth will occur after puberty has concluded. However, maintaining a healthy lifestyle can support overall development and well-being. This includes regular exercise, a balanced diet, and adequate sleep, all of which contribute to hormonal balance and physical health.

Additionally, weight can play a role in the perceived size of the penis. If an individual carries excess weight, particularly around the pelvic area, it can make the penis appear smaller than it actually is. Losing weight may help reduce the fat pad around the pubic area, potentially making the penis appear larger, even if its actual size does not change.

If you have concerns about your development or if you feel that your growth is significantly delayed compared to peers, it may be beneficial to consult a healthcare professional. They can provide personalized advice and, if necessary, conduct evaluations to ensure that your development is on track.

In summary, while it is unlikely that you will see significant increases in penis size after puberty, it is essential to focus on overall health and well-being. Embrace your body as it is, and remember that confidence and personality are key factors in forming relationships. Many people find that qualities such as kindness, humor, and intelligence are far more attractive than physical attributes alone.
