Bill overview
This bill aims to establish specific, biological definitions for the terms ‘male,’ ‘female,’ ‘boy,’ ‘girl,’ ‘father,’ ‘mother,’ ‘man,’ and ‘woman’ within federal law. It clarifies that ‘female’ is defined by the ability to produce eggs, ‘male’ by the ability to produce sperm, and explicitly states that ‘gender identity’ should not be used as a substitute for biological sex in federal regulations. The bill seeks to provide a consistent and clear understanding of these terms across various government agencies.
