Description
Sirarat Ittipuripat and co-authors test a late-start birth control pill plan in a 2025 trial. Starting the pill a week into the cycle could cut the risk of an unplanned pregnancy for women who start late. A newer pill mix with a natural-type hormone had little data for such late starts.
Thirty-six healthy women with steady cycles were split by lot between the new mix and an older one. Both groups began on day seven to nine of the cycle. Staff checked whether egg release was blocked as it should be. The trial asks whether the new mix is no worse than the old at this late start, a fact clinics need.
