Mack R. K. Beggs (born 1999) is an American former high school wrestler from Euless, Texas.
[5][6] His State Championships were considered controversial by some because of the low doses of testosterone Beggs was taking beginning his high school freshman year.
Citing the possible advantages testosterone could give Beggs over his female wrestling competitors, some wrestlers and their parents protested, some even forfeiting matches.
[9] In 2018, Beggs was given an opportunity to wrestle at the collegiate level as a walk-on in the men's division at a NAIA school.
[2] Beggs has called on state legislators to alter University Interscholastic League regulations that require athletes to compete under their gender assigned at birth.
