NCT ID NCT07169591

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study looks at how different types of hormonal birth control affect the way young, healthy women process sugar. Researchers will compare three groups: women not on birth control, those taking birth control pills, and those using an IUD. Participants will drink a sugary solution and have blood drawn over two hours to measure glucose and insulin levels.
