In 2012, Annet Negesa qualified to represent Uganda in the 800-meter run at the London Olympics. But just weeks before the Games, she got a call from her agent. A test had shown high levels of naturally-occurring testosterone in her blood. She would not be allowed to compete. In an attempt to restore her eligibility, Annet underwent a serious, irreversible surgery that derailed her career and left her with serious medical side effects. Now, Annet is sharing her story to try to help other women avoid the same fate.
