"Athletics “have become part of the fabric of America.” Nat’l Collegiate Athletic Ass’n v. Alston, 141 S. Ct. 2141, 2168 (2021) (Kavanagh, J., concurring). Women’s ability to “participate equally in the economic and social life of the Nation”—including through high school, collegiate, and professional sports—“has been facilitated by their ability to control their reproductive lives.” Casey, 505 U.S. at 856 (plurality opinion). Absent the right to access safe and legal abortion care, and the ability of “the woman to retain the ultimate control over her destiny and her body,” id. at 869, women’s sports would not be the enormous success they are today. Among other reasons, women’s ability to participate and excel in athletics would decline, severely impairing the vitality of sports in the United States. Further, women and girls would be deprived of the multitude of collateral benefits that result from athletic participation, including greater educational success, career advancement, enhanced self-esteem, and improved health. Athletic prowess depends on bodily integrity. The physical body is a critical tool for athletes, and its condition determines elite athletes’ futures and livelihoods. High school and collegiate athletes use their bodies not only to compete, but also to secure higher education through recruiting opportunities and athletic scholarships that may be otherwise unobtainable. Professional athletes use their bodies for their livelihoods, including to access lucrative sponsorships and advertising opportunities. Amici depend on the right to control their bodies and reproductive lives in order to reach their athletic potential. Indeed, Amici are united in their belief that the physical tolls of forced pregnancy and childbirth would undermine athletes’ ability to actualize their full human potential."
