This section provides context and methodology details for the data presented:
- **Data Scope:** This table focuses exclusively on Male athletes at the K-12 level who have participated on a girls' team.
- **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 alphabetically by default.
Other Notes:
- Totals here represent male youth athletes who have participated in high school, middle school, and elementary school athletics in the "girls" division in the United States.
- "State" as referenced here refers to the location of the athlete's school that has allowed the male to particpate on the girls' team. The athlete may have participated in competitions outside their home state, for example South Eugene High School has participated in competitions outside of Oregon. To view competition locations, see the results page.
- Many awards for named athletes are not available. The totals here do not represent every award the athletes may have received.
- Many high school and youth athletes remain unnamed and as such are not represented in the results here.
