The South African was forced by a 2019 World Athletics rule to take medication to suppress her testosterone levels.
Two-time Olympic champion Caster Semenya has won her appeal at the European Court of Human Rights to challenge athletics' testosterone rules.
The South African, who won 800-metre gold in 2012 and 2016, was forced by a 2019 World Athletics rule to take medication to suppress her testosterone levels.
That meant she was unable to defend her title at the Tokyo Games.
A World Athletics' statement says that it notes the court's decision but until a final ruling is made the current regulations will stand.
