The Texas Senate sent legislation to Gov. Greg Abbott (R) that would strictly define genders across state law based on male and female reproductive organs — potentially creating new hurdles for transgender and intersex Texans whose gender identity would revert to the sex they were assigned at birth in state records.

Abbott’s office didn’t immediately respond to The Hill’s request for comment about his plans for the bill once it hits his desk. Supporters of the legislation said that it follows a directive Abbot issued earlier this year that state government in “Texas recognizes only two sexes — male and female.”

Abbott cited in the directive an executive order that President Trump signed shortly after his January inauguration that designates male and female as the only sexes recognized by the federal government and on a biological basis.

“All Texas agencies must ensure that agency rules, internal policies, employment practices, and other actions comply with the law and the biological reality that there are only two sexes—male and female,” Abbott wrote in his January letter to state agencies.

The latest Senate-approved bill, dubbed the “Women’s Bill of Rights,” defines sex as “an individual’s biological sex, either male or female.” Under the legislation, a woman or female is an “individual whose biological reproductive system is developed to produce ova” and a male or man is “someone whose reproductive system is developed to fertilize the ova of a female.”

Additionally, it defines “mother” as “a parent of the female sex.”

Critics of the measure argue that the bill oversimplifies sex, gender and a broad spectrum of personal experiences.

“If a law forces non-binary Texans, who are real people, into categories that don’t reflect their lived experiences or identities … that would actually become discrimination in practice,” State Sen. Sen. José Menéndez (D) said during the floor debate on the bill before its passage. “That’s a concern that I have.”

State Sen. Mayes Middleton (R), who sponsored the bill, said that it would preserve women’s designated spaces, like restrooms and prisons, based on “biological reality.” He noted that it carries no criminal or civil penalties.

“For our entire history we never had to define this because common sense dictated we didn’t, but unfortunately, that seems to have changed,” he said in the floor debate.

Abbott has previously pushed back against past criticism for signing laws that target LGBTQ people. He approved legislation in 2023 and 2021 to bar transgender athletes from competing in women’s and girls’ sports in Texas schools and colleges.
