Caster Semenya has never doubted that she was a woman. It wasn’t until her athletics career started to take off that the now two-time Olympic Games gold medallist and a three-time World Athletics Championships gold medallist faced any questions over her gender. Called a ‘threat to the sport’ and ‘not woman enough’, she has become the most visible DSD (difference in sex development) athlete today, and found herself at the centre of the debate around the newly drawn line between gender and sport. In this episode of Ways to Change the World, she tells Krishnan Guru-Murthy about her experiences as an athlete with a difference in sex development, her tumultuous journey to the top of the athletics world, and what being a woman means to her.
