Dr George Lee returns to discuss the latest medical news. Expect deep insights delivered with generous humour. Olympic gold medallist Mokgadi Caster Semenya is a South African female athlete who has been barred from competing internationally under the women’s category in running events. It’s not because she took illegal performance-enhancing drugs or changed her body artificially. It’s because she was born as a woman with higher-than-usual testosterone levels. Consultant urologist Dr George Lee helps us to understand Semenya’s situation and what it means for female athletes.
