Mental stress led to anti-doping charge - Vondrousova

Former Wimbledon champion Marketa Vondrousova says she was at "breaking point after months of physical and mental stress" when she refused a visit from a doping control officer to her home in December 2025.

The Czech player has been charged with refusing a doping test by the International Tennis Integrity Agency (ITIA) after denying the officer entry to conduct the test.

Players are required to log their whereabouts for an allotted hour each day so that authorities can conduct anti-doping tests outside of competition.

Should the 26-year-old be found guilty of the charge, she could be banned for up to four years.

But Vondrousova says she feared for her safety when the officer called at her home and said they failed to follow "protocol".

"The recent doping control incident happened because I reached a breaking point after months of physical and mental stress," Vondrousova wrote on Instagram.

"When someone rang my door late at night without properly identifying themselves or following protocol - I reacted as a person who felt scared.

"In that moment it was about feeling safe, not about avoiding anything."

The 2023 Wimbledon women's singles champion added that "experts confirmed" she had "suffered an acute stress reaction and generalised anxiety disorder".

The ITIA said it was "aware of the player's comments" and, while it could "confirm that an investigation is under way and the player has been charged with refusing a test", it was "not able to comment any further on the specifics".

Vondrousova, who is 46th in the women's rankings, can continue playing as the offence does not incur an immediate ban and she has opted not to take a provisional suspension.

However, she has not played since withdrawing from the Adelaide International in January with shoulder pain. She went on to miss the Australian Open with the same issue.

ITIA rules say a player "evading sample collection or refusing or failing to submit to sample collection without compelling justification after notification by a duly authorised person" is deemed to have committed an anti-doping violation.

"It is very tough for me to talk about this, but I want to be transparent with you about my mental health," added Vondrousova in her social media post.
