Embracing post-fertilisation methods of family planning: a call to action

In this commentary, the authors present an argument for developing a family planning method that could be used after fertilization. Such a method could be used later after sex than emergency contraceptives and could possibly be used only when a woman’s menstrual period is delayed. While there would likely be political fallout, a post-fertilization method would likely appeal to many women and thus efforts to produce such a method would be worthwhile.
