Boys show a clear athletic advantage over girls even before puberty.

Performance data from Little Athletics Australia¹ reveals that boys outperform girls in every track and field event from under-9 to under-15 age groups, even prior to puberty. This challenges the common claim that pre-pubertal boys or those on puberty blockers have no competitive edge over girls. The male performance advantage appears early in childhood and is evident across sprinting, jumping, and throwing events.
