Well, rehabilitate the withdrawal method of course! So check out this ABC article which cites studies to “show” that the withdrawal method is on par with condom use for efficacy in preventing pregnancy.
Obviously it won’t help with other common problems…….
So with withdrawal rehabilitated to acceptability as a contraceptive method, then Plan B might still be thought of as “effective”.
Or maybe getting both of these into common usage will sell a lot more abortions.
