Birth control pills and bones: a new study raises questions
NCT ID NCT04007614
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to look at bone health in young women aged 16 to 25 who took a specific type of birth control pill (macro-progestins) for at least six months. Researchers planned to review medical records and run blood and urine tests to see if these pills affected bone density. However, the study was withdrawn before any participants were enrolled, so no results are available.
