This bill requires certified national governing bodies (NGBs) of amateur sports (e.g., USA Gymnastics) to prohibit a person whose sex is male from participating in an amateur athletic competition that is designated for females, women, or girls.

Under the bill, male means an individual who has, had, will have—or would have, but for a developmental or genetic anomaly or historical accident—the reproductive system that at some point produces, transports, and utilizes sperm for fertilization.
