WASHINGTON (March 28, 2025) – U.S. Senators Bill Cassidy, M.D. (R-LA), Roger Marshall (R-KS), Tim Sheehy (R-MT), Cindy Hyde-Smith (R-MS), and Pete Ricketts (R-NE) introduced the Defining Male and Female Act of 2025to codify President Trump’s executive order establishing legal definitions of male, female, and sex to ensure they are based on biological reality rather than radical, left-wing ideology. The order entitled “Defending Women From Gender Ideology Extremism and Restoring Biological Truth to the Federal Government,” which clarifies that sex is determined at conception and ensures the federal government uses this sex dichotomy.
“Common sense and science tell us there are two sexes,” said Dr. Cassidy. “You are born a male or a female.”
“The Democrats’ radical transgender agenda is dangerous and wrong. We shouldn’t need legislation to tell us the basic reality that there are only two sexes, but here we are,” said Senator Marshall. “I’m thankful President Trump has made this a top priority and signed an Executive Order on his first day in office recognizing that there are only two sexes. Congress must ensure this historic action is written into law by passing the Defining Male and Female Act.”
“Boys are boys, girls are girls, and gone are the days of woke nonsense like calling mothers ‘birthing persons.’ Supporting this legislation is a no-brainer and I’m proud to be restoring common sense in America,” said Senator Sheehy.
“By affirming biological truth, we defend fairness in sports, safeguard women and children, and uphold the principles of Title IX as Congress intended,” said Senator Hyde-Smith. “Because the other side spent four years pretending boys were girls, it’s time to restore common sense once and for all by establishing clear, legal, and biologically-accurate definitions of male and female.”
“This bill is simple. It defines the most basic science. There are only two sexes: male and female,” said Senator Ricketts. “Defining males and females is an important step to helping protect our women and girls across America.”
U.S. Representative Mary Miller (R-IL-15) introduced companion legislation in the U.S. House of Representatives.
“Now more than ever, we must unite to uphold the truth and biological reality established by God that there are only two sexes,” said Representative Miller. “I am proud to stand alongside Senator Marshall in introducing the House companion to the Defining Male and Female Act to ensure our nation upholds common sense and puts an end to the Left’s dangerous and extreme sexual fantasies.”
Specifically, the Defining Male and Female Act recognizes:
- The definition of male and female on the basis of a person belonging, at conception, to the sex characterized by a reproductive system with the biological function of producing eggs or producing sperm.
- The right of girls and women to sex-separate sports and scholarships.
- The sex separation of restrooms, locker rooms, dorm rooms, prisons, and shelters for victims of sexual assault.
