"The demands of athletics and pregnancy are physically and emotionally intense. If women were to lose the agency to make individual, personal choices as to if, when, and how to balance these competing demands, many will be forced to sacrifice their athletic aspirations and pursuits. Compelled pregnancies would allow the State to “conscript[] women’s bodies into its service, forc[e] women to continue their pregnancies, suffer the pains of childbirth, and in most instances, provide years of maternal care.” Casey, 505 U.S. at 928 (Blackmun, J., concurring). Often this will be at the expense of women’s athletic careers, as well as their educational goals and professional livelihoods. Such “governmental intrusion” is “unique to the [woman’s] condition,” id. at 851–52, as only women’s bodies are essential for both athletic participation and pregnancy and childbirth. Depriving women of the opportunity to make autonomous choices about how to use their bodies—a matter “of the highest privacy and the most personal nature,” id. at 915 (Stevens, J., concurring)—would gravely harm equality in athletics, and elsewhere."
