What it does
This bill amends federal law governing amateur sports organizations to define 'female,' 'male,' and 'sex' based on reproductive biology, and requires that organizations prohibit males from competing in female-designated athletic competitions. The bill directly affects eligibility rules for Olympic and amateur sports governing bodies, potentially excluding transgender women from female competition categories.
Why we flagged it
The bill's operative mechanism is a categorical eligibility rule for amateur sports competition based on biological-sex classification. It is not a deregulation, subsidy, or commemorative measure—it is a direct restriction on who may compete in female-designated categories.
What the text implies
- The bill's definition of 'female' and 'male' by reproductive-system capacity may create legal ambiguity for individuals with differences of sex development (DSDs), intersex conditions, or medical histories that do not fit the stated reproductive criteria, potentially triggering disputes over eligibility determinations.
- The phrase 'would have, but for a developmental or genetic anomaly or historical accident' attempts to include individuals whose reproductive systems were altered by medical intervention, accident, or developmental variation—but the scope and application of this carve-out is undefined and may invite litigation.

Who it affects
The bill aims to protect opportunities for female athletes in competition, a legitimate public interest; however, it does so by imposing a biological-sex-based eligibility rule that may exclude transgender women and individuals with differences of sex development (DSDs), creating a real cost to those groups' athletic participation rights. Both the benefit to cisgender female athletes and the exclusion of transgender/DSD athletes are concrete civic effects.
