"The HPG hormones that define teen puberty actually start within weeks of conception and continue in the first months of life before going dormant until about the age of 8. This exposure lays down a dimorphic foundation upon which further physical and cognitive development will occur - and that foundation cannot be undone or modified. Against this backdrop the idea of “wrong puberty” is nonsensical, with teen puberty merely the conclusion of a process that has been proceeding for the child’s entire life."
