Section 16-1-52
Participation in athletic events to be based on biological sex of athletes.
(a) The Legislature finds and declares the following:
(1) Physical differences between biological males and biological females have long made separate and sex-specific sports teams important so that female athletes can have equal opportunities to compete in sports.
(2) Physical advantages for biological males relevant to sports include, on average, a larger body size with more skeletal muscle mass, a lower percentage of body fat, and greater maximal delivery of anaerobic and aerobic energy than biological females.
(3) Even at young ages, biological males typically score higher than biological females on cardiovascular endurance, muscular strength, muscular endurance, and speed and agility. These differences become more pronounced during and after puberty as biological males produce higher levels of testosterone. On average, biological male athletes are bigger, faster, stronger, and more physically powerful than their biological female counterparts. This results in a significant sports performance gap between the sexes.
(4) Studies have shown that the benefits that natural testosterone provides to biological male athletes is not significantly diminished through the use of testosterone suppression. Testosterone suppression in biological males does not result in a level playing field between biological male and biological female athletes.
(5) Because of the physical differences between biological males and biological females, having separate athletic teams based on the athletes' biological sex reduces the chance of injury to biological female athletes and promotes sex equality. It provides opportunities for biological female athletes to compete against their peers rather than against biological male athletes, and allows biological female athletes to compete on a fair playing field for scholarships and other athletic accomplishments.
(b)(1) Except as provided in subsection (c), a public K-12 school may not participate in, sponsor, or provide coaching staff for interscholastic athletic events within this state that are either scheduled by or conducted under the authority of any athletic association of the state that permits or allows participation in athletic events within the state conducted exclusively for males by any individual who is not a biological male or participation in athletic events within the state conducted exclusively for females by any individual who is not a biological female.
(2) A public K-12 school may not allow a biological female to participate on a male team if there is a female team in a sport. A public K-12 school may not allow a biological male to participate on a female team.
(c) This section does not apply to athletic events at which both biological males and biological females are permitted or allowed to participate.
