Double Olympic 800-metres champion, Caster Semenya, says she is optimistic of success in her appeal to the Court of Arbitration for Sport (CAS) over eligibility regulations in athletics for female classification.

The court in Switzerland postponed its verdict from the five-day hearing in February, due to be delivered next week, until the end of April, with no fixed date set.

The International Association of Athletics Federations (IAAF) contends that Semenya and other female athletes that are classed as having differences in sexual development (DSDs) gain an unfair advantage due to their higher testosterone levels.

It says this is only the case in races between 400 and 1000 metres. Under the IAAF’s new rules, which are currently suspended pending the outcome of the CAS case, athletes classed as having DSDs must medically reduce their blood testosterone level for a continuous period of six months before they can compete.
