Marketa Vondrousova, who won Wimbledon in 2023, has been suspended from tennis for four years due to her refusal to participate in an anti-doping test. The incident took place in December 2025 and has sparked considerable debate within the sport. Vondrousova's decision to refuse the test has been attributed to her experiencing an Acute Stress Reaction, which has raised questions about the circumstances surrounding her refusal. The ban is a significant blow to the Czech player, who had recently achieved the pinnacle of her career with her Grand Slam victory. This suspension underscores the ongoing challenges the sport faces in maintaining its integrity and the importance of compliance with doping regulations.
