If you'd said to people 50 years ago we are going to have to define in law exactly what is a woman and a man I think they would have laughed at you.
But that's what the Governor of Oklahoma has done to protect primarily women's rights to privacy and fairness in sports competition.

"Gov. Stitt’s order enacts language directly from the bills. The order defines a female as “a natural person . . . whose biological reproductive system is designed to produce ova.” A male is defined as “a natural person . . . whose biological reproductive system is designed to fertilize the ova of a female.” The order also defines mother, father, man, boy, woman, girl, sex, and natural person. The executive order requires all state agencies, including public schools, to use the listed definitions when determining an individual’s sex.It also requires them to provide “governmental services in single-sex environments where biology, privacy, and personal dignity are implicated.”“. . . prisons and other correctional facilities are directed to provide dedicated facilities for men and women respectively. Likewise, schools are directed to provide dedicated restrooms and locker room facilities for boys and girls, respectively,” the executive order reads."
