Olympic champion runner Caster Semenya expressed her disappointment Sunday with the International Olympic Committee and called out IOC president Kirsty Coventry following the IOC's recent decision to ban transgender athletes from competing in the Games.

The decision also restricts female athletes such as Semenya with medical conditions known as differences in sex development, or DSD.

Semenya, of South Africa, said after a women's race promoted to celebrate female strength, unity and community support that she expected more from Coventry, a native of Zimbabwe.

"Personally, for her as a leader, she's an African, I'm sure she understands how, you know, we as Africans, we are coming from, as a global South, you know, you cannot control genetics," Semenya said at a March 29 news conference in Cape Town.

The IOC issued the ban on March 26, reversing its 2004 decision to allow the participation of transgender women athletes.
