First things first. Turns out "efficacy" and "effectiveness" don't mean the same thing, even though the words are often thrown around interchangeably, even by reliable sources! The distinction between these two words is v. important! Here's why: Birth control efficacy refers to how well each form of birth control fulfills its intended duty (preventing pregnancy) in perfect-use situations. A perfect-use situation is not a real life situation, but instead something like a clinical trial in which only the months or cycles where the birth control method was used consistently and correctly are taken into the equation. It accounts for pregnancies that occur even with this consistent and correct use of the prescribed method. Effectiveness on the other hand, refers to how well each form of birth control prevents pregnancy in typical-use situations, meaning, the average Joe at home in a real life, day-to-day setting. This takes into account human error and covers all pregnancies and months, keeping in mind the possibility of human inaccuracies or imperfect use.
