evidence: The Paris Olympics was at the centre of a major controversy after a ‘gender row’ erupted in women’s boxing. Algerian boxer Imane Khelif was accused of being a ‘biological male’, leading her opponent — Italy’s Angela Carini — to withdraw from their match after just 46 seconds. While Carini apologised on Friday for her post-match behaviour, terming it frustration from her dream of winning the gold "going up in smoke", social media was already embroiled in debates over Khelif’s gender status amid allegations that she is a man or trans-gender and should be banned from the women’s event. Some global media reports indicated that a test conducted by the International Boxing Association (IBA) had revealed that the Algerian boxer has XY chromosomes [male] and thus did not meet their eligibility requirements. [...] Decoding the complex make-up of chromosomes, Dr Ambrish Mithal, chairman and head, endocrinology and diabetes at Max Healthcare, Saket, New Delhi, explained that the media reports indicate that "Khelif has a deficiency in 5-alfa reductase (5-ARD)". "This means that while she was conceived as a boy with XY chromosomes, the penis, scrotum and testes did not fully develop and at first sight, she looked like a girl and was registered as such."
