Actually, to be pedantic, use whichever is appropriate to your use-case.

If you are looking at biological/physiological attributes (chromosomes,
hormones, testicular-cancer, ...), use "sex."

If you are tracking social attributes or characteristics (preferred
dress-style, sexual-preference, income, prevalence in various
professional roles, etc.), use "gender."

See http://www.who.int/gender/whatisgender/en/

Either way, an expandable lookup-table may end up being useful. Just
when you think you are strictly dealing with "sex" and you hard-code for
"male" and "female", someone will show up and ask you to rewrite your
code to account for chimeras
(http://en.wikipedia.org/wiki/Chimera_%28genetics%29).
