Constitutional delay of puberty in males

Some boys grow and enter puberty later than classmates but continue to develop in a healthy pattern. Family members may have had a similar later growth spurt. Puberty is assessed through changes such as testicular enlargement, body hair, voice change, and growth acceleration, rather than age alone. A clinician also asks about nutrition, intense exercise, long-term illness, medicines, smell, headaches, and emotional wellbeing. Turner Syndrome is not a typical explanation for delayed puberty in males, but a clinician may consider chromosome or other medical conditions when the findings do not fit a simple family pattern.

A paediatrician or endocrinologist can compare current growth with earlier measurements and family timing. Bring school health records, medication information, and details of relatives' puberty patterns. The review may include examination, hormone blood tests, and a hand or wrist growth scan. Monitoring may be enough when development is progressing appropriately. If delay is causing significant distress or social difficulty, a clinician may discuss a brief supervised course of testosterone; this should not be started without medical guidance.

Arrange an assessment when there are no signs of progression, growth has slowed, weight loss or persistent digestive symptoms occur, or a chronic condition may be affecting development. Headaches, vision changes, marked tiredness, or loss of smell need medical attention. Emotional distress, teasing, and withdrawal from sport or friends are also valid reasons to seek support. See the Delayed Puberty overview for related symptoms.

Ask whether the pattern looks familial, which tests are appropriate, how progress will be monitored, and whether treatment could help wellbeing. Ask what changes should prompt an earlier review and how to discuss privacy with school staff.
