Establishes the "Defining SEX Act"

Where it is in the process
Plain-English Summary

This bill, known as the "Defining SEX Act," adds a new section to chapter 213 of Missouri law to define "female," "male," and "sex" based on biological reproductive systems. It clarifies that in existing state law, "gender" will be considered a synonym for "sex" and not for "gender identity," "experienced gender," "gender expression," or "gender role." The bill also states that individuals with a medically verifiable disorder or difference in sex development will receive protections under the federal Americans with Disabilities Act.
