Puberty blockers should be prescribed when puberty actually begins, not at a predetermined age. Research shows that the timing depends entirely on your individual child's development, as puberty starts at different times for every child.

Evidence indicates that puberty blockers are most effective when given at the onset of puberty rather than before or after significant changes have already occurred. For some children, this might be as early as eight or nine years old, whilst others may not begin puberty until later. The key principle is that puberty blockers work by blocking puberty, so timing is crucial for their effectiveness.

Guidelines recommend that healthcare providers assess each child individually, looking for the early signs of puberty such as breast development, testicular growth, or changes in body odour and mood. This allows children who are questioning their gender identity the time and space to explore their feelings without the distress of unwanted physical development.

The decision about timing requires careful assessment by qualified healthcare professionals who can monitor your child's physical development alongside their emotional wellbeing. This personalised approach ensures that treatment aligns with your child's unique developmental timeline and needs.
