H.B. No. 229 establishes new definitions and guidelines regarding biological sex within Texas law. The bill asserts that males and females have distinct biological differences that are immutable and significant, particularly in contexts such as pregnancy, physical strength, and vulnerability to violence. It emphasizes the importance of recognizing these differences in various settings, including athletics, correctional facilities, and shelters, while also clarifying that policies distinguishing between sexes must meet constitutional scrutiny. The bill defines terms such as "boy," "girl," "male," "female," "man," "woman," "father," and "mother" based on biological reproductive systems, and it states that individuals diagnosed with intersex conditions are not classified as a third sex but must receive appropriate accommodations.

Additionally, the bill introduces a new subchapter in the Government Code that mandates governmental entities to collect vital statistics information identifying individuals as either male or female for compliance with antidiscrimination laws and for public health and data purposes. This collection of information is intended to ensure clarity and consistency in the identification of biological sex across various governmental functions. The act is set to take effect on September 1, 2025.
