Testosterone in Sports: A Controversial IssueTestosterone, a sex hormone produced by both men and women, has become a contentious topic in the world of sports. While men naturally produce significantly higher levels of testosterone, women can also have elevated levels due to conditions like polycystic ovary syndrome.In sports, testosterone can enhance bone and muscle mass, making it a potential performance-enhancing substance. However, the extent to which it boosts performance remains a subject of debate. The International Olympic Committee (IOC) acknowledges that there is no scientific consensus on the matter.The issue gained prominence at the 2021 Tokyo Games with the participation of Laurel Hubbard, the first openly transgender woman to compete in an Olympic event. To qualify, she had to maintain testosterone levels below 10 nmol per liter for at least 12 months. Despite meeting the requirements, her participation drew criticism.In 2022, Algerian boxer Imane Khelif was disqualified from the boxing world championships due to elevated testosterone levels. However, the International Boxing Association (IBA) has since stated that she did not undergo a testosterone examination but was subject to a separate test with confidential specifics.The IOC has taken responsibility for organizing boxing at the Paris Games due to governance issues at the IBA. IOC spokesman Mark Adams emphasized that all participants in the women's event comply with eligibility rules and that testosterone levels alone cannot determine eligibility.The controversy surrounding testosterone in sports highlights the complex interplay between biology, gender, and athletic performance. While it is essential to ensure fair competition, it is equally important to avoid discriminatory practices based on natural variations in hormone levels.
