- New rules introduced for athletes with Differences of Sexual Development
- Athletes will have to reduce and maintain testosterone levels
- Rules will come into force in November
(CNN)New regulations governing testosterone levels in female athletes are "blatant racism," says South Africa's ruling party the African National Congress (ANC).
In a statement, the party compared the new rules to government policies in apartheid South Africa.
The regulations, which were announced by athletics' governing body the IAAF Thursday, will limit the testosterone levels of female athletes competing between 400m and a mile.
They are aimed at athletes with Differences of Sex Development and are widely reported to impact South Africa's double Olympic champion Caster Semenya.
"The African National Congress (ANC) notes with great concern the International Association of Athletes Federation's (IAAF) new regulations on female testosterone," read a statement.
"These new regulations infringe on the human rights of athletes, targeting mainly those in East Europe, Asia and the African continent.
"The racial undertones of this cannot go unnoticed. The regulations are a painful reminder of our past where an unjust government specifically legislated laws for certain activists in society to stifle their fight against an unjust system."
