Gender diversity and gender-affirming paediatric care — formative SAQs

SAQ 1 — The peripubertal adolescent and pubertal suppression (10 marks)

A 12-year-old assigned male at birth has, since early childhood, been consistent, persistent and insistent about a female identity. With the onset of puberty she describes intensifying distress about penile growth and the prospect of voice deepening. Tanner stage 2 is confirmed. A multidisciplinary assessment supports a diagnosis of persistent gender dysphoria; she has capacity to assent and her parents consent. ^{[2] [3]}

Questions

1. Outline the staged, reversible-first gender-affirming pathway, naming each stage and its reversibility. (5 marks) ^{[2] [1]}
2. Justify pubertal suppression with a GnRH analogue at this point, and state the eligibility criteria that should be met before it is commenced. (3 marks) ^{[2] [7]}
3. Describe the bone-health surveillance required while she is on suppression and explain why. (2 marks) ^[10]

Model answer

Staged, reversible-first pathway (5). The pathway moves from the most reversible to the least reversible step, with psychosocial support throughout. Stage 1 is exploration and psychosocial support — open, non-directive counselling, treatment of comorbidity, family and school work — and is fully reversible. Stage 2 is social transition (affirmed name, pronouns, appearance, environment), also fully reversible. Stage 3 is pubertal suppression with a GnRH analogue, fully reversible. Stage 4 is gender-affirming hormones (oestrogen or testosterone), typically from mid-adolescence in specialist programmes, partially reversible. Stage 5 is gender-affirming surgery, largely irreversible and usually an adult-service option, with chest masculinisation occasionally considered in older, long-persistent adolescents. ^{[2] [1] [3]}

Justification and eligibility for suppression (3). Suppression at Tanner 2 prevents the unwanted, increasingly permanent secondary sex characteristics of endogenous puberty that drive much of the distress, and buys decision-making time without closing any future door — it is fully reversible, and stopping it allows endogenous puberty to resume. Eligibility: persistent, well-documented gender dysphoria; an accurate early pubertal (Tanner 2) stage; multidisciplinary specialist assessment; any comorbid mental-health condition addressed; and the young person's assent together with parental (or legal) consent. ^{[2] [7]}

Bone-health surveillance (2). Adolescence is when sex steroids drive bone-mineral accrual; a GnRH analogue pauses that accrual, so density drifts down relative to peers during suppression and recovers only partially and later. Surveillance therefore includes baseline and periodic DXA, optimisation of calcium and vitamin D, and encouragement of weight-bearing activity. ^[10]
