Olympic 800m champion Caster Semenya has won her appeal at the European Court of Human Rights in a case involving testosterone levels in female athletes.
Semenya, 32, was legally identified as female at birth but has a condition which means her body naturally produces higher levels of testosterone than women without the condition. The South African runner's differences of sexual development (DSD) mean that she isn't allowed to compete in events between 400m and a mile without taking testosterone-reducing drugs.
Due to this, Semenya has been in a lengthy dispute with World Athletics since regulations requiring her to take hormone treatment to decrease her natural testosterone levels were introduced five years ago. On two previous occasions, at the Court of Arbitration for Sport and the Swiss Federal Supreme Court, she failed in legal battles to overturn the decision.
