Explaining a constitutional delay of puberty diagnosis to an adolescent and his family — OSCE

Task

Counsel the boy and his parents together. You have five minutes. Demonstrate an organised, empathic and accurate explanation that addresses the four questions a fellowship communication station rewards: what is happening to him and why he is short and prepubertal when his peers are not, what the investigations show, what the management options are including short-course testosterone, and why the prognosis for final height and fertility is excellent. The counselling framework follows the standard approach to constitutional delay of growth and puberty. [1]

What the family needs to hear

Open by addressing the boy directly as well as the parents, and name the distress. He has been bullied about his size, and that is the thing that matters most to him right now — acknowledge it before any of the medicine. Then explain the diagnosis in plain language: his body has its own internal clock that tells it when to start puberty, and his clock is simply running a little late. This is not an illness, it is not a sign that something is wrong with him, and it is not a permanent condition — it runs in families, and both his parents went through exactly the same pattern of being the last to grow and then catching up completely. [2]

Address the parents' fear that he will 'never develop' directly and dissolve it. The investigations support a diagnosis of constitutional delay: his bone age — which is a way of reading how biologically mature his skeleton is — lags his real age by two and a half years, meaning his body is working with the clock of an eleven-and-a-half-year-old, and on that clock he is entirely on track. His hormone tests show the pattern of a clock that has not yet switched on, which is exactly what constitutional delay looks like. Reassure them that the clock will switch on, and when it does he will go through puberty and a growth spurt just like everyone else, finishing at a height close to what his genes predict. [1] [2]

The management options — practical and shared

Lay out the options so the family can decide together. The first option is simply to wait and review: come back in six months, measure his growth and his testes, and confirm that puberty has begun on its own. This is perfectly safe and is what most families choose, because the clock will start without any help. The second option, which we can consider because the bullying is affecting him now, is a short course of testosterone — a hormone injection once a month for three to six months that starts the changes of puberty and gives him a growth spurt, so that he catches up with his peers and the bullying eases. [12]

Explain the testosterone course honestly. It is not a lifelong treatment, it will not make him taller than his genes allow, and it will not advance his bone age dangerously if given for the short period we use. What it does is start puberty a little earlier than his clock would have, relieve his distress, and confirm that his body can respond — which is reassuring in itself. Ask the boy what he wants: many adolescents in this situation are relieved to have the option, and the decision is his as much as his parents'. Frame the shared decision around his priorities, not just the endocrinology. [12] [1]

The prognosis and the close

Close by affirming the excellent prognosis. With or without the short course, he will go through full puberty, reach an adult height within the normal range, have normal bone strength, and have normal fertility — constitutional delay does not affect any of these. The main thing we are managing today is not a disease but his confidence and his place among his peers, and that is worth taking seriously. Agree on the plan — whether to wait or to start the testosterone course — book the review, and offer the school a letter explaining the diagnosis to support him with the bullying. End by inviting any further questions and confirming that the door is open. [1] [2]
