The bill S. 1158 aims to amend the South Carolina Code of Laws by adding Chapter 140 to Title 44, which specifically prohibits the genetic modification of human embryos to alter their biological sex. It establishes that no practitioner or facility is allowed to knowingly perform, attempt to perform, or assist in such genetic modifications.

Additionally, the bill outlines penalties for violations of this prohibition. A person found guilty of altering the biological sex of a human embryo would face felony charges, with potential fines of up to twenty thousand dollars, imprisonment for up to ten years, or both. Furthermore, the individual's professional license would be revoked by the relevant licensing authority, and each instance of violation would be treated as a separate offense. The act is set to take effect upon the Governor's approval.
