What should be communicated to the mother of a 16-year-old boy with small testes and no secondary sexual characteristics?

The appropriate communication in this situation centers on the evaluation of the boy's development. The presence of small testes and the absence of secondary sexual characteristics in a 16-year-old indicates a potential delay in sexual maturation, which is not typical for this age. Normal physiological development should include the onset of these characteristics during puberty, which usually begins around age 12 and progresses over the next few years.

Referring the boy to a pediatric endocrinologist is essential because it allows for a comprehensive evaluation of his hormone levels and overall growth patterns. This specialist can assess whether there may be underlying conditions, such as hypogonadism or other endocrine disorders, contributing to the delay in development. Identifying and addressing such issues early is crucial for the boy's long-term physical and psychological well-being.

Other options do not accurately reflect the clinical scenario. Suggesting that the boy is developing normally overlooks the key indicators of delayed puberty. Recommending a recheck in three months without a full evaluation fails to address the potential need for intervention. Stating that his development is slower but within the lower limit may mislead the mother into thinking this situation is safe when it actually requires further investigation.
