Ask a casual tennis fan to name the Frenchwoman who came from almost nowhere to reach the semifinals of the 2025 French Open, and you might get a blank stare. That player is Loïs Boisson, a 21-year-old who won her first WTA-level title in Hamburg in 2025 (WTA official tour record).

What is Loïs Boisson’s current ranking in singles?
Boisson is currently World No. 36, a career high she set at the end of the 2025 season. That number is the practical answer to the search query, but it hides the real story: she got there after an ACL injury and a French Open run that started from outside the top 300.
Career-high rank and progression
- May 2024 — career-high No. 152 after the WTA 125 Saint-Malo title.
- May 2024 — ACL injury at the Paris WTA 125, ending her season.
- End of 2025 — career-high No. 36.
The three data points above come from the WTA official tour record.
Ranking breakdown by year
The 2025 French Open entry ranking is the missing link most summaries ignore.
From No. 361 at the 2025 French Open to No. 36 by year’s end, the ranking table is a comeback in numbers.
| Period | WTA singles ranking |
|---|---|
| May 2024 | No. 152 (career high) |
| 2024 season | Ended by ACL injury |
| 2025 French Open entry | No. 361, the lowest-ranked semifinalist in 40 years (Sporting News) |
| End of 2025 | No. 36 |
The pattern: Boisson’s ranking did not climb steadily — it jumped, crashed, and rebuilt within two seasons. That non-linear rise matters more than the final number when assessing her 2026 potential.
What happened to Lois Boisson?
The short version: 2024 ended with an ACL tear, 2025 began near the bottom of the tour’s entry lists, and by summer she had a WTA title and a French Open semifinal. The controversy that interrupted that run had nothing to do with doping or a ban.
2024 Saint-Malo breakthrough and injury
- Boisson won the WTA 125 Saint-Malo title as part of an 18-match ITF winning streak.
- The ACL injury at the Paris WTA 125 ended her season before she could build on that breakout.
Hamburg 2025 title and comeback
- Her maiden WTA-level singles title was Hamburg 2025, not 2024 — she beat Anna Bondár in the final.
- In that final, she recovered from a 1-5 first-set deficit, the kind of comeback that defined her post-injury confidence.
Many early search results dated Boisson’s first WTA title to 2024. The official WTA record places the Hamburg title in 2025, after the Saint-Malo WTA 125 title in 2024 and the ACL injury that followed.
Suspension or controversy?
No WTA suspension is on the public record. The Rouen incident was a complaint about smell, not a violation of tennis’s anti-doping or conduct rules.
The deodorant story happened at the 2025 Rouen Open. In the first round, Harriet Dart asked the umpire to tell Boisson to wear deodorant (BBC Sport (UK broadcaster)). Boisson won 6-0, 6-3 (Tennis.com (tennis news site)). No disciplinary action has been announced.
The pattern: the Rouen episode produced the louder search headline, while the Hamburg trophy and No. 36 ranking carry the career.
Why is Lois Boisson so muscular?
Boisson’s build draws attention because it is visibly different from many other WTA players. The sources reviewed for this article contain no evidence of performance-enhancing drug use; the more plausible explanation is a late start at age 8 and a strength-first style that developed quickly.
Training regimen and genetics
- She started tennis at 8, late for a future pro, which made physical work central to her game.
- Her 2025 French Open wins over Mirra Andreeva and Jessica Pegula show the payoff under pressure.
The “muscular” search query usually hides a doping question. The official record contains no anti-doping case; the useful question is how she built that power legally and quickly.
Comparison to other tennis players
- Comparisons to power players like Taylor Townsend are common, but Boisson’s 2025 season has its own shape.
- Her 2025 French Open run made her the tournament’s lowest-ranked semifinalist in 40 years, according to Sporting News (sports outlet).
What this means: muscle is not a scandal and not a science project — it is the visible product of a short development window and a game designed to finish points.
Who told Lois Boisson to wear deodorant?
The documented answer is Harriet Dart. During their first-round match at the 2025 Rouen Open, Dart asked the umpire to relay the message (BBC Sport).
The origin of the deodorant story
“Dart asked the umpire to tell Boisson to wear deodorant and said Boisson smelled really bad.”
BBC Sport report
Boisson’s response was decisive: a 6-0, 6-3 win, which Tennis.com (tennis news site) called the perfect answer to the controversy.
Fan or coach advice?
- No fan or coach request appears in any source reviewed for this article.
- The only documented request came from Dart, relayed by the umpire, according to BBC Sport.
The pattern: a search-friendly phrase attached itself to a low-stakes on-court complaint, and the rumor outran the scoreline. The actual story has one player making the request, one umpire relaying it, and a 6-0, 6-3 punchline.
Who is Lois Boisson’s coach?
Public record is thin. The WTA profile used for this article does not list a named head coach, and no coaching name emerged in the coverage reviewed.
Current coaching team
- No named head coach appears in the WTA official record for Boisson.
- Her 2025 breakthrough came in the same season she returned from ACL rehab, which makes the unnamed coaching and medical team’s work central to the story.
Previous coaches
- Sporting News’ feature on her French Open run does not name a junior or early pro coach.
- No coach change was found in the research notes.
What this means: the coach answer is a gap, not a scoop. Until Boisson or the WTA publishes a coaching credit, any specific name online should be treated as rumor.
Career timeline
The timeline below draws on the WTA official record linked above and Sporting News reporting.
- — Born in Dijon, France.
- — Started playing tennis at age 8.
- — Turned professional and made her WTA Tour debut in Lyon doubles.
- — Won Saint-Malo WTA 125 title and reached No. 152.
- — ACL injury at Paris WTA 125 ended her season.
- — Won Hamburg WTA title over Anna Bondár.
- — Reached French Open semifinals as a wild card, beating Andreeva and Pegula.
- — Career-high No. 36.
The pattern: the injury gap, not the wins, is the reason her ranking arc looks like a zigzag instead of a ladder.
What’s confirmed vs. still unclear
Confirmed facts
- Hamburg 2025 was her first WTA-level singles title, not 2024 (WTA official tour record).
- She reached the 2025 French Open semifinals as a wild card (WTA official tour record).
- Harriet Dart asked the umpire about deodorant at Rouen (BBC Sport).
What’s unclear
- Whether any fine, warning, or suspension followed the Rouen incident — no official confirmation is public.
- Who, beyond Dart’s on-court request, might have told Boisson to wear deodorant.
- The current names on her coaching and medical team.
The pattern: the confirmed list is longer than the rumor list, but the unanswered coaching question remains a hole in an otherwise documented career.
Quotes and reactions
“Boisson’s maiden WTA-level singles title came at Hamburg in 2025, where she defeated Anna Bondár in the final.”
WTA official record
“Dart asked the umpire to tell Boisson to wear deodorant and said Boisson smelled really bad.”
BBC Sport
“Boisson was expected to receive a wild card for the 2024 French Open before her ACL injury.”
Sporting News
The pattern: the official record, the BBC report, and Sporting News agree on the results; the only disagreement is how loudly the deodorant distraction is repeated.
Bottom line
Boisson’s 2025 season settled two arguments: her Hamburg title and French Open semifinal were real, and the deodorant incident was a one-match distraction she answered with a 6-0, 6-3 win. The next question is whether her body and ranking hold up across a full 2026 schedule. For French tennis fans, the choice is clear: treat Boisson as a top-36 player until she proves otherwise, or get left behind by a comeback that already reset the national rankings.
