Champion runner Caster Semenya opened up about her fight to compete against other women in track events without having to reduce her testosterone levels.

Semenya was born with a difference in sex development (DSD). She was legally identified as female at birth but has a medical condition that leads to some male traits, including increased levels of testosterone.

The 32-year-old South African runner and others have been able to compete without restrictions in events outside the range of 400 meters through one mile but now have to undergo hormone-suppressing treatment for six months before competing to become eligible. World Athletics tightened the rules earlier this year.

"For me, I believe if you are a woman, you are a woman," she told BBC in a recent interview. "I have realized I want to live my life and fight for what I think and I believe in myself. I don’t care about the medical terms or what they tell me. Being born without a uterus or internal testicles. Those don’t make me less of a woman. I am a woman and have a vagina just like any other woman."

Under the new regulations, athletes in previously "unrestricted" events would have to suppress testosterone levels below 2.5 nanomoles per liter of blood for six months and stay before those levels for two years.
