>>81728158The claim that the female body is the default is an oversimplification and biologically inaccurate. Human embryos start from a common undifferentiated structure, not a female one. Sexual differentiation is driven by genetic and hormonal signals, most notably the SRY gene on the Y chromosome. This gene triggers the development of testes, which then produce androgens that masculinize the body. The reason all humans have nipples is not because we start as female, but because nipple development occurs before the process of sexual differentiation begins. Saying it is easier to provoke a change than to revert it is meaningless hand waving and has no basis in actual developmental biology. Embryonic development is not some reversible toggle; it is a tightly regulated sequence of gene expression and tissue differentiation. This entire line of reasoning reflects a shallow and outdated understanding of human biology and should not be repeated without proper context or correction.
