The field of sex and gender is extremely controversial and has contributed to a proliferation of terms whose meanings vary over time and within and between studies. The term “gender identity,” distinct from the term “sexual orientation,” refers to a person’s innate, deeply felt psychological identification as a man, woman or some other gender, which may or may not correspond to the sex assigned to them at birth [1].Stein 1999 stated that, “Someone who has the feeling that they are a different sex than the one that they were born – to some extent” [2]. “Sexual orientation” refers to an individual’s physical and/or emotional attraction to the same and/or opposite gender [1].
