What is infantile genitalia?

According to Louann Brizendine, MD (a neuropsychiatrist and the author of The Female Brain, published in 2006), infantile puberty pertains to a 24-month period wherein a female infant experiences an estrogen (a female hormone, which is responsible for maintaining their reproductive health) release of levels similar to what an adult female experiences in her teens (the actual "puberty"). This

• according to Louann - results in early development of many brain

circuits (eg, communication) early on, which makes female infants more communicative & social and less aggressive.
