Markéta Vondroušová's four-year doping ban for refusing anti-doping test
Consensus Summary
Markéta Vondroušová, the 2023 Wimbledon champion and former world No 6, has been suspended for four years by the International Tennis Integrity Agency (ITIA) after refusing an out-of-competition doping test at her home on December 3, 2025. The tribunal ruled that her refusal—despite claiming mental health struggles and fear of strangers—provided no compelling justification, treating the incident as equivalent to a positive doping test. Vondroušová, who has never tested positive and has a history of compliance with anti-doping rules, signed a refusal form after being approached by a doping control officer outside her designated testing window. She can appeal the decision to the Court of Arbitration for Sport. The case has sparked debate among players, with some, like Ajla Tomljanovic, criticizing the ITIA for harsh treatment, while others, such as Karolina Pliskova, argue the rules are clear and must be followed. The ban, one of the most severe in tennis history for a refusal, underscores the sport’s strict anti-doping policies and the challenges of unpredictable testing protocols.
