Edelman AB et al. are to be congratulated for reporting the results of yet another well designed, meaningful study — this time studying the impact early administration of oral contraceptives might have on the ability of ulipristal acetate to delay ovulation [
]. The only concern I have is with the paper's conclusion: “This study demonstrates that UPA's efficacy as an emerging contraceptive is reduced with early exposure to COC.”
