WASHINGTON, D.C. (LifeSiteNews) – It is the official policy of the United States once more to maintain a biology-based definition of “sex” across all federal agencies, according to a new memo from the U.S. Department of Health & Human Services (HHS).
The February 19 memo lays out the understanding of sex and related terminology to be used for the purposes of interpreting and abiding by federal rules, regulations, and partnerships.
“There are only two sexes, female and male, because there are only two types of gametes,” it says. “An individual human is either female or male based on whether the person is of the sex characterized by a reproductive system with the biological function of producing eggs (ova) or sperm. The sex of a human, female or male, is determined genetically at conception (fertilization), and is observable before birth.”
Sex, the memo continues, “is unchangeable and determined by objective biology. The use of hormones or surgical interventions do not change a person’s sex because such actions do not change the type of gamete that the person’s reproductive system has the biological function to produce. Rare disorders of sexual development do not constitute a third sex because these disorders do not lead to the production of a third gamete.”
The memo concludes by defining “female,” “male,” “woman,” “girl,” “man,” “boy,” “mother,” and “father” accordingly, based on observable scientific fact rather than subjective thoughts or feelings of gender dysphoria.
“It took many years of effort but we are finally back to science and common sense,” reacted Roger Severino, former director of the HHS Office for Civil Rights (OCR) in the first Trump administration.

It is an article of progressive faith that gender is no more than a matter of self-perception that individuals are free to change at will. But according to modern biology, sex is not a subjective sense of self but an objective scientific reality, established by an individual’s chromosomes from their earliest moments of existence and reflected by hundreds of genetically based characteristics.
Yet for years LGBT activists have worked to promote “gender fluidity,” the idea that sexual identity is separate from biology and discernible only by personal perception, across public education, libraries, health care, and cultural traditions such as beauty contests, school homecomings, and athletic competitions.
Critics say their efforts have yielded a wide array of harms, both to the physical and mental health of gender-confused individuals themselves as well as to the rights, health, and safety of those who disagree, such as girls and women forced to share intimate facilities with males, female athletes forced to compete against biological males with natural physical advantages, and individuals forced to affirm false sexual identities in violation of their consciences, their understanding of scientific fact, and/or their religious beliefs.
Since returning to office, President Donald Trump has taken multiple executive actions to reverse the Biden administration’s transgender policies, including an order that ends all federal support for “transition” procedures on minors, rescinds or amends all of the Biden health bureaucracy’s past endorsements of underage “transitioning,” and calls for a review of the medical literature on the subject, enforcing all existing restrictions on underage “transitioning,” and taking regulatory action to “end” the practice to the greatest extent possible under current law.
Another order prohibits males who claim to be female from competing against actual women in sex-specific athletic programs at schools receiving government funding. A third disqualifies gender-confused individuals from military service and prohibits military health services from conducting “transition” treatments and procedures.
