Scientifically, Gender refers to the biological sex of an organism. In common culture, it can be used in a multitude of other ways, however. Possible meanings include, but are not limited to:
- The gender role one acts according to
- The gender one dresses as (see cross-dressing)
- Any number of sexual orientations.
- The sex one believes one most closely identifies with in terms of hormones, testosterone, and estrogen.
- Or any other way one wishes to label oneself in terms of sex or sexual preference/orientation
The gender of humans is usually determined at birth by a quick examination of the genitals. Normally, if the baby has a vagina, it is identified as a female, whereas if it has a penis and testicles, it is identified as a male. However, in rare cases, a baby can be born with ambiguous genitalia, or can be born with one set of genitals, but with the chromosomes of the opposite sex.
