This section provides context and methodology details for the data presented:
- **Data Scope:** This table focuses exclusively on competitive results where a Male athlete participated in an event or competition originally intended for female athletes. This applies to events specifically labeled "female", "women" or "girls" or events that were originally female-only but have been changed to mixed sex to be "inclusive" of some males, but continue to exclude other males who do not claim to be women. This includes events labeled "women+" or similar. Events that are mixed but in which there are specific limits on the number of male and female athletes per team and in which the male athlete has taken a "female" position, such as mixed doubles in tennis, are also included.
- **Link Verification:** The provided links are to external sources. These sources include official results directly from the event webpages, sites that aggregrate athletic results from various organizations (such as MileSplit.com), news stories, and social media posts from team and athlete accounts. Archived links (Ar.) are provided in the case that these results are removed or websites are no longer functional. Not all pages were able to be archived. When possible, archived links can most often be found in the second (2) link.
- **Athlete Verification:** Athletes have been verified as male through the use of public sources: news articles, personal declarations from the athletes, name changes, past photos, and other public records including job history, school records, and family records. In the case of males with DSDs, athletes are included if they have previously failed a sex/gender test.
- **Athlete Identification:** "DSD" refers to male athletes with a disorder of sexual development. These athletes are male but may have been mistaken for female at birth due to underdeveloped male genitalia. "Trans-identified" refers to male athletes who have had healthy male development but deny that they are men and boys and claim to be something else, typically "women" or "nonbinary". "Other" refers to males who do not belong in either of the former categories but participate on female teams due to rule exceptions.
- **Sorting:** The table is sorted by **Date (newest first)** by default.
Other Notes:
- Both league standings and tournament results are listed for Women's Football Alliance (WFA) teams. Standings are given for both the team's placement within their conference and the division. Conference and national championship results are decided through post-season tournaments.
- When conference champions are decided through league standings rather than a post-season tournament, the end-of-season standing will be listed as a "conference championship."
- Although the WFA and Premier rugby players do not receive payment, they are still commonly referred to as "professionals" and will be labeled here as such.
- Male athlete Michael "Michelle" Tat has posted on his social media about numerous instances of participation in flag football tournaments with the Boston Midnight Riders. His accounts were made private before these results could be recorded, and as such, they will not appear here until more details can be unconvered.
- Male athlete Lorcán Mac An TSionnaigh goes by both "Ella Nic An TSionnaigh" and "Ella Ni Fhaolain." Per Irish naming conventions "Mac An" means "the son of" while "Nic An" means "the daughter of." "Ni" can also mean "grandaughter of".
- In addition to the two male athletes on the Melbourne University Australian rules football team, a third unidentified male athlete also participated on the 2023 team. The Melbourne team now avoids calling their players "ladies" or "girls" and instead insists they call themselves "mugs," a practice opposed by many of the women on the team as they felt it was stripping away their identity as women.
- An unidentified male athlete playing on the Guam High School rugby team in 2022 injured at least three players in the first matches of the season. Further information is not known at this time.
