This celebratory article from Outsports gives the names of 28 male athletes claiming trans identities who either "have won national or international competitions" in women's sports or have racked up other major wins in the female category.
As you can see from the dates given in the article, the majority of the male athletes who are named have won big in women's and girls competition the past 5-6 years, and all except one have done so in the current century.
BTW, the list of names given by Outsports is far from complete. It leaves out a number of male athletes claiming trans identities who have racked up big wins and been awarded newsworthy titles and honors in female competition. Such as surfer Sasha Jane Lowerson, who at age 43 became the top title-holder in two Australian women's surfing events that Lowerson previously won when competing in the men's category; American June Eastwood, whose accomplishments in women's college running led to Eastwood being named Big Sky Conference Female Athlete of the Week; and Stephanie Barrett, a top-tier performer in Canadian, Pan American and world elite women's archery who was chosen to take the single spot given to Canada in women's archery at the 2021 Tokyo Olympics - quite a feat for someone who first picked a bow only 5 years before at age 37.
