Governmental Biological Sex Definitions

A bill to define and collect government info about biological sex.

• Biological sex: The physical traits a person is born with, like body parts, chromosomes, and hormones, that are used to label someone as male or female at birth.

The first part of the bill lists some ideas about biological sex that Texas leaders have based this bill around. These ideas say that a person’s gender has to reflect what people typically think of with the biological sex they were said to be when they were born. For example, if the person was called “female” then they must be a “girl” who is a “mom.” 

• This ignores transgender people, who for example, may have been called female when they were born, but don’t feel like a girl or want to be a mom.

The first part of the bill also says that laws that are for each sex have to pass checks that say they line up with what the constitution says.

The second part of this bill changes part of the Government Code to say the following:

• "Boy" means a child who is male.

• "Father" means a parent who is male.

• "Female" and "woman" refer to someone whose reproductive system makes ova.

  • Ova: tiny cells in a woman's body, also called egg cells, that can join with a man's sperm cell to start the process of making a baby.

• "Girl" means a child who is female.

• "Male" and "man" refer to someone whose reproductive system fertilizes ova.

  • Fertilizing: when a man's sperm cell joins with a woman's egg cell (ova), beginning the creation of a baby.

• "Mother" means a parent who is female.

• "Sex" means a person's biological sex, either male or female.

• Government Code: a big set of rules that explains how the government in Texas should work and what it can and cannot do.

The third part of the bill changes part of the Government Code to add the following:

• A part about collecting Vital Statistics Information, which are important details about people's lives, like records of births, deaths, marriages, and divorces.

• Defining "governmental entity" as any organization that is part of the government.

• A rule that Governmental entities collecting vital stats must say whether people are male or female.

If this bill passes, these changes start on September 1, 2025.
