Gonadal sex refers to the gonads, that is the testicles or ovaries, depending on which genes are expressed. Phenotypic sex refers to the structures of the external and internal genitalia. [6]
Determination of sex is a process by which scientists and medical professionals determine the biological sex of a person or other animal using genetics and biological sexual traits. It is not to be confused with sex assignment which is a more recent colloquial term that allows for the use of non-sexual or non-genetic traits to define a person's ...
Gender identity is the personal sense of one's own gender. [1] Gender identity can correlate with a person's assigned sex or can differ from it. In most individuals, the various biological determinants of sex are congruent and consistent with the individual's gender identity. [2]

There are no examples of ...
