Although that's funny, the ethical considerations of heterosexual couples on a long space flight are rather important.
No one knows what happens if you get pregnant in space. No one knows what happens to such a baby. (No one's admitted to having sex in space, although it's generally suspected to have happened.) (See https://www.acityonmars.com/ because the book discusses this in more detail.)
Birth control isn't 100% effective. If couples are having sex in space, we have to assume that they will get pregnant. I personally don't like the idea of forcing astronauts to get abortions; but in this case, the unknowns of a fetus developing in 0-g makes it quite a conundrum that makes my brain hurt.
