The bill H. 3506 aims to amend the South Carolina Code of Laws by adding Article 29 to Chapter 1, Title 1, which provides specific definitions and rules of construction regarding human biological sexes for the purposes of state laws, administrative regulations, and guidelines. It asserts that there are only two sexes, male and female, which correspond to distinct biological characteristics observable at or before birth. The bill emphasizes that an individual's sex is not determined by self-identification and seeks to clarify the meanings of terms related to sex, gender, and their implications in legal contexts.

Key definitions included in the bill specify that "female" and "male" refer to individuals with reproductive systems that produce eggs and sperm, respectively, and that "gender" should be treated as synonymous with sex in legal contexts. The bill also clarifies that the definitions of "sex," "male," and "female" do not exclude reasonable accommodations for individuals with disorders of sex development (DSD). Additionally, it includes a severability clause to ensure that if any part of the act is deemed unconstitutional, the remaining provisions will still be valid. The act is set to take effect upon the Governor's approval.
