Summary (Continued) These sexual dimensions are “inborn” Sexual dimensions are organized (from default to fully altered) by genetic and/or hormonal factors during critical periods of fetal development Activated later by hormones Variations are not necessarily disorders Variations are natural events that are the source of diversity in a population Diversity in a population is an asset, not a liability

These sexual dimensions are “inborn”

Sexual dimensions are organized (from default to fully altered) by genetic and/or hormonal factors during critical periods of fetal development

Activated later by hormones

Variations are not necessarily disorders

Variations are natural events that are the source of diversity in a population

Diversity in a population is an asset, not a liability
