Document Summary

High levels of parental testosterone one starting in the 8th week of gestation lead to male- seeming genitals and low levels lead to female-seeming genitals. The link between genes and genitals is by way of prenatal testosterone but very rarely, the genitals do not match the abs genetic makeup or are blending of male and female genitals. Prenatal hormone levels affect the development of brain structures such as the amygdala (reactions to threats) and the prefrontal cortex (planning, judgement, self-control) Sex hormones: testosterone is obviously higher for males than females but levels can vary within each gender depending on prenatal environment as measured by the mothers amniotic. Girls with more expose to testosterone prenatally had more masculine features by 3. 5y. Linked with less relationships, more interest in girls, more masculine activities. Congenital adrenal hyperplasia (cah): overproduction in androgens which can effect both genders. In girls, it causes genitals to develop in a masculine direction.
