UPA > LNG, but Not Good Enough [What Do We Need to Know about Emergency Contraception?]

Abstract

In this issue of Contraception Brache et al. report pooled data from three randomized trials on the efficacy of emergency contraception (EC) pill regimens to prevent ovulation. The efficacy of EC methods depends on several factors including how and when they are being used and their mechanisms of action. An ideal EC method should be safe and acceptable, easy to use (by the woman), readily available, effective when used at least up to 120h after the unprotected intercourse (the time period corresponding to the life span of sperm), and have mechanisms of action that makes it effective during the entire fertile window.
