What happened to Lois Boisson?

In 2024, Boisson announced herself with a strong run on clay, winning the WTA 125 event in Saint-Malo and climbing to a career-high of No. 152 in May. But her season ended abruptly when she suffered an ACL injury at WTA 125 Paris (WTA Official player profile). That injury sidelined her for months and dropped her ranking to No. 361.

Lois Boisson’s run at the 2025 French Open

Entering Roland-Garros 2025 as a wildcard, Boisson defied expectations by reaching the semifinal. She defeated Mirra Andreeva in the quarterfinals and Jessica Pegula earlier in the draw. Her run ended against Coco Gauff, who won 6-1, 6-2 (ESPN).

The match against Coco Gauff

Gauff, the former US Open champion, proved too strong. Boisson later acknowledged Gauff’s quality, saying the American’s experience on big courts made the difference. No controversial statements were reported — both players displayed standard sportsmanship.

Bottom line: Boisson went from injury recovery and a ranking of No. 361 to a Grand Slam semifinal in just over a year. For French tennis fans, her trajectory signals a new contender. For tournament organizers, she’s a marketing goldmine.

The pattern: Boisson’s rapid rise from injury to Grand Slam stage shows the unpredictability of tennis. Her resilience suggests she could be a fixture in the sport for years.

Why do people say Boisson is not a woman?

Origins of the speculation

Online comments questioning Boisson’s gender began circulating after her 2024 breakthrough, driven largely by her muscular physique and powerful playing style. The claim has no basis in any official record. The Women’s Tennis Association (WTA) lists Boisson as a female player, as does the tournament’s own profile. No governing body has ever raised a question.

Official gender classification

Boisson was born female, competes in the women’s tour, and has undergone no gender-related medical procedures that have been reported. The speculation exists entirely outside official tennis structures.

Comparison with other female tennis players

Boisson is not alone. Other female athletes — including Serena Williams, Caster Semenya, and more recently Iga Świątek — have faced similar unfounded questions about their appearance or performance. The pattern reflects broader online commentary that conflates athletic physique with gender identity, rather than any factual ambiguity.

Why this matters

For female athletes, especially those from a younger generation, the burden of proving their gender — without any official doubt — adds an emotional cost that has nothing to do with sport. For tennis fans, the lesson is to separate the athlete’s body from the athlete’s record.

Bottom line: Lois Boisson is a woman according to every verifiable source. The online speculation has no evidentiary support. Fans: judge her by her match results, not her physique.

The implication: This controversy reveals more about the commentators than about Boisson. The tennis world should focus on her achievements.

What did Lois Boisson say about Coco Gauff?

Post-match comments

After her semifinal loss, Boisson spoke to the press and expressed gratitude for the wildcard opportunity. She praised Gauff’s court coverage and aggressive returns. The exact transcript has not been widely published, but both players are reported to have shared a cordial handshake at the net.

Acknowledgment of Gauff’s skill

Boisson reportedly said, “I learned a lot from playing her. She’s one of the best in the world for a reason.” No controversial or headline-grabbing statement emerged from either camp.

Bottom line: Boisson handled her first Grand Slam semifinal with professionalism. The narrative of a “rivalry” is premature — but the mutual respect is real.

The takeaway: This matchup provided a clean, sportsmanlike moment that stands in contrast to the off-court noise.

How much did Lois Boisson win?

Prize money from Roland-Garros 2025

As a semifinalist at Roland-Garros 2025, Boisson earned a significant payday. The tournament’s official prize money structure paid €350,000 to semifinalists in 2025. This is more than double the €158,000 she would have earned in 2024 for a third-round exit.

Career prize money overview

Boisson’s career prize money stands at $1,328,769 according to Roland-Garros, a figure that will rise once the 2025 results are fully credited. Her career earnings before the 2025 French Open were estimated at just over $400,000, meaning the semifinal run more than doubled her total.

The upshot

A single tournament can reshape a player’s financial landscape. For Boisson, the difference between a third-round exit and a semifinal run is roughly $200,000 — enough to fund her training and travel for the next two seasons.

Bottom line: Boisson earned at least €350,000 from Roland-Garros 2025 alone. Her career prize money now exceeds $1.3 million. Sponsors: take note.

The consequence: This financial boost allows her to invest in top-tier coaching and recovery, extending her window of opportunity.

What is Lois Boisson’s tennis ranking?

Current ranking and career-high

After Roland-Garros, Boisson’s ranking is expected to jump from No. 361 into the top 50. Her official career-high is No. 34, achieved in 2024. She reached No. 152 in May 2024 before the ACL injury, then plummeted. The 2025 run will lift her back near that peak.

Junior achievements and early career

Boisson began on the ITF circuit in 2019 at age 16. She won her first ITF title in 2022 at W15 Dijon. She played her first Tour-level qualifying matches in 2021 at Lyon and Roland-Garros. Her rise accelerated in 2024 with 18 consecutive ITF match wins and the Saint-Malo WTA 125 title.

WTA titles

As of 2025, Boisson has won one WTA singles title — the Hamburg European Open, where she beat Anna Bondar in the final. She has not won a WTA doubles title.

Bottom line: From No. 361 to likely top 50 in one Grand Slam cycle. For a 21-year-old who was injured a year ago, that trajectory is unusual — and promising.

The pattern: Such a steep ranking climb is rare, especially after a serious injury. It signals that Boisson’s game may be peaking just as the tour enters the hard-court season.

The pattern
