Abstract
Progestin-only pills (POPs) are often referred to as “mini-pills” as they contain about 75 % of the progestin dose contained in combination oral contraceptives (COCs) and no estrogen. Their typical effectiveness has been shown to be slightly less than COCs; most likely due to a more limited duration of effect and inconsistent ovulation suppression. POPs are associated with more breakthrough bleeding than COCs but fewer serious adverse events. Although not as well studied, POPs are thought to have many of the same non-contraceptive health benefits as COCs.
