It may seem appalling now. But up until uncomfortably recent times, say a couple hundred years ago or so (a mere blink of history), infanticide was the primary form of birth control. It still is practiced in some less developed countries, in fact. Anyways, I assume by the early 20th century, that method had largely fallen into disuse. At least in western postindustrial nations. So what did people, I'm thinking prostitutes esp., do just before the introduction of the Pill, in the 1950's? I must not be the only person who ever wondered this.
