South Africa’s track and field federation had been asked to conduct a gender test on an 800-meter runner amid concerns that she does not meet the requirements to compete as a woman.

Caster Semenya is the 18-year-old South African runner who is undergoing a series of gender tests to prove she was born a woman. Semenya dominated her rivals and won the gold medal in the 800-meter race at the World Championships on Wednesday, despite revelations that surfaced earlier in the day claiming she was undergoing a gender verification test due to concerns that she does not meet the requirements to compete against female athletes.

“She said to me she doesn’t see what the big deal is all about,” South Africa team manager Phiwe Mlangeni-Tsholetsane said Thursday.

Caster’s father also has a hard time believing that his daughter has been accused of packing a penis.

“She is my little girl,” Jacob Semenya told a Sowetan newspaper. “I raised her and I have never doubted her gender. She is a woman and I can repeat that a million times.”

Semenya’s paternal grandmother, Maputhi Sekgala, said the controversy “doesn’t bother me that much because I know she’s a woman.”

“What can I do when they call her a man, when she’s really not a man? It is God who made her look that way.”
