Another emerging and related view is that gender identity…is also fixed at birth or at a very early age and can diverge from a person’s biological sex.
In biology, an organism is male or female if it is structured to perform one of the respective roles in reproduction…[which] provide the conceptual basis for the differentiation of animals into the biological categories of male and female.
But this definition of the biological category of sex is not universally accepted. For example, philosopher and legal scholar Edward Stein maintains that infertility poses a crucial problem for defining sex in terms of reproductive roles, writing that defining sex in terms of these roles would define “infertile males as females.”
As we have seen above in the overview of the neurobiological and genetic research on the origins of gender identity, there is little evidence that the phenomenon of transgender identity has a biological basis. There is also little evidence that gender identity issues have a high rate of persistence in children.
