Summary

This study looks at how long-acting reversible contraceptives (like implants or IUDs) affect iron levels and how women's bodies respond to extreme heat, cold, and high altitude. Researchers will compare women using these contraceptives to those on birth control pills. The goal is to understand if these methods impact health and performance in challenging environments.
