Olympics permit biological men to compete in women's sports is one thing; pretending that it is fair, is something else.There is no argument that a person's sex is determined at the moment of conception, and that fertilization of an egg occurs with either an "X" or "Y" sperm cell, which will only determine one of two sexes.
Following conception, the development pathways of males and females diverge immediately and substantially, right down to a cellular DNA level.
These bifurcating pathways endure throughout an individual's lifetime.Every single nucleated cell in the human body has 46 sex-specific "XY" chromosomes (denoting biological male sex) or "XX" chromosomes (denoting biological female sex).
These nucleated cells in turn have sex-specific functions which guide their development and biological function.Indeed, sex is not just "skin deep." It persists down to a microscopic, cellular level, and biological sex is indicated within the 100 trillion (or so) cells in the human body.Bottom line: the indelible imprint of biological sex—determined in utero and at the moment of conception—is not scientifically or clinically possible to alter.This physiological difference cannot be suppressed by any amount of synthetic hormones or "puberty blockers"—known scientifically as "gonadotropin-releasing hormone agonists." HHS's Office of Population Affairs (OPA) says their use in children is "safe" and "reversible" in its widely touted official, final guidance document.
