Summary

This study looks at whether a hormonal implant containing gestrinone affects blood vessel function and heart health in young women. Researchers will compare women who have used the implant in the last six months with those who have never used it. The goal is to understand any potential cardiovascular risks or benefits associated with this type of contraception.
