Delayed Voice Change and Adam's Apple Development - Urology

Share to:

Please ask your question, thank you?


I am currently eighteen years old, but I have not experienced voice changes or developed an Adam's apple.
What could this condition indicate? However, I have body hair and other aspects of development are normal.
Which type of doctor should I see at the hospital? Thank you for your response!

The manifestations of secondary sexual characteristics may not always be very obvious.
Moreover, if there is already body hair, it is advisable to visit a hospital and consult a family medicine or urology specialist for a preliminary examination if there are concerns.

More Info


The development of voice change and the prominence of the Adam's apple (laryngeal prominence) are typically associated with puberty, particularly in males. This process is largely driven by hormonal changes, specifically the increase in testosterone levels, which leads to the growth of the larynx and the vocal cords. As a result, the voice deepens, and the Adam's apple becomes more pronounced.

In your case, at 18 years old, if you have not experienced a voice change or the development of an Adam's apple, it could be due to several factors. Firstly, it is essential to consider that the timing of puberty can vary significantly among individuals. While many boys experience voice changes between the ages of 11 and 15, some may experience these changes later. Genetic factors can play a role in this variability, as can overall health and nutrition.

However, if you are experiencing other signs of puberty, such as body hair growth, it suggests that your body is undergoing some hormonal changes. The absence of voice change and Adam's apple development could indicate a delay in the specific aspects of your puberty related to the larynx. This condition is sometimes referred to as delayed puberty, which is defined as the absence of secondary sexual characteristics by age 14 in boys.

If you are concerned about your development, it would be advisable to consult a healthcare professional. An endocrinologist, a doctor specializing in hormones and the endocrine system, would be the most appropriate specialist to evaluate your situation. They can assess your growth patterns, hormone levels, and overall development to determine if there is an underlying issue that needs to be addressed.

In some cases, delayed puberty can be a normal variation, but it can also be associated with conditions such as hypogonadism (where the body doesn't produce enough testosterone), Klinefelter syndrome (a genetic condition affecting male physical and cognitive development), or other hormonal imbalances. A thorough evaluation, including blood tests to check hormone levels and possibly imaging studies, may be necessary to rule out any underlying conditions.

In summary, while it is not uncommon for some individuals to experience variations in the timing of puberty, consulting with a healthcare professional is essential for peace of mind and to ensure that there are no underlying health issues. They can provide guidance, support, and potential treatment options if necessary.
