Science fiction most often takes place in societies with more advanced technology than ours. Since our world has effective birth control, it seems reasonable to assume that most science fiction societies would have even more reliable birth control, would have had it for longer than we’ve had it, and, thus, would have integrated it more fully into their cultures. In such societies, an unplanned pregnancy would be virtually unheard of—unless it were related to social prohibitions against birth control or to some weird alien/nefarious/divine intervention. Yet much of science fiction TV and film treats unplanned pregnancies as if they were the natural order of things.
