Adam's Apple Development and Growth Concerns in Adolescents - Internal Medicine

Adam's apple


Hello doctor, I am 17 years old and my height is only 165 cm.
My Adam's apple is still not prominent, and I can say that I have no noticeable external changes.
I haven't grown taller since the second year of junior high school (less than one centimeter in a year).
I have a lot of body hair, but my genitalia has not increased in size.
Does this mean I am experiencing abnormal development? My voice sounds very feminine.
I am unsure if I have completed my growth period and whether I can still grow taller.
Is it possible for my voice to change back? Please let me know, thank you.

Thank you very much for your letter.
However, based on the information provided, it is not possible to determine whether it is normal.
I recommend that you schedule an appointment with an endocrinologist for a detailed discussion.

Understanding the development of the Adam's apple and growth concerns during adolescence is crucial for both physical and psychological well-being. At 17 years old, you are at a stage where many physical changes associated with puberty should have occurred, but it is important to recognize that development can vary significantly from person to person.

The Adam's apple, or laryngeal prominence, is a feature that typically becomes more pronounced in males during puberty due to the growth of the larynx and the influence of testosterone. This growth usually begins around the ages of 11 to 14 and can continue into the late teens. If you have not noticed significant changes in this area, it may be a sign that your body is still undergoing changes or that your development is occurring at a different pace than your peers.

Regarding your height, it is common for growth spurts to occur during puberty, but the timing and extent of these spurts can vary widely. Many individuals experience a significant increase in height during early to mid-adolescence, while others may have a more gradual growth pattern. If you have not grown in height for a year, it is possible that you may be nearing the end of your growth phase, especially if your growth plates have closed. Growth plates typically close after puberty, and this process can be influenced by various factors, including genetics and hormonal levels.

As for your concerns about body hair and genital development, it is important to understand that these changes can also vary greatly among individuals. The presence of body hair does not necessarily correlate with the size of the genitals or the development of secondary sexual characteristics. If you are experiencing significant anxiety about your development, it may be beneficial to consult with a healthcare professional, such as an endocrinologist or a pediatrician, who can evaluate your growth and development more comprehensively.

Regarding your voice, it is common for adolescent males to experience changes in voice pitch during puberty due to the growth of the larynx. If your voice has not deepened significantly, this could be related to the timing of your hormonal changes. In some cases, voice changes can continue into the late teens. If you are concerned about your voice or if it is causing you distress, a speech therapist or an otolaryngologist (ear, nose, and throat specialist) may provide guidance and support.

In summary, while it is understandable to have concerns about your development, it is essential to remember that everyone grows at their own pace. If you are worried about your growth, development, or any other physical changes, seeking medical advice can provide clarity and reassurance. A healthcare professional can assess your individual situation, possibly conduct tests to evaluate hormone levels, and help you understand what to expect moving forward. Remember, you are not alone in this journey, and there are resources available to support you.

Precocious puberty can affect height, but it seems you have not reached that level yet. A height of 163 cm in the first year of junior high school is still considered acceptable.
