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 introduces specific definitions for terms such as "boy," "girl," "male," "female," "man," and "woman," all of which are tied to biological reproductive systems.

Additionally, the bill mandates that governmental entities collecting vital statistics must categorize individuals strictly as either male or female for compliance with antidiscrimination laws and for data collection purposes. This requirement aims to ensure consistency in the identification of biological sex across various governmental functions. The act is set to take effect on September 1, 2025.
