Summary

This study looks at whether two types of hormonal birth control pills (LF111 and drospirenone) affect bone density in women aged 14 to 45. Over 1,500 participants will have their bone density measured after 12 months and compared to women using non-hormonal birth control. The goal is to understand any risks to bone health from these contraceptives.
