I don't think you need man/woman in a language like toki pona either, it's supposed to be this deep philosophical language. If you want to talk philosophy, reproduction is the least of your problems. There's plenty of ways to indicate the sex as well. so long as you have the word for animal/organism, you can say animal + hole/stick, who nurses for the young, hunter, whatever. Its even better because its not exact. the more exact you get, the more words you'll need.
