“Receiving [information designed to counter gender stereotyping] at an early age is critical. There has been a steady decline in the average age at which puberty begins. Among those assigned female at birth, some breast development by age seven and eight is no longer an anomaly. The age of the onset of puberty has also fallen for those assigned male at birth, from an average of age 11 to 10.5.”
