Not always the case.(XX)
"It is true that in typical male development, the SRY gene on the tip of the Y chromosome helps to send the embryo down the masculine pathway. But more than the SRY is needed for sex determination and differentiation; for example, women with CAIS have the SRY gene but lack androgen receptors. In terms of hormone effects on their bodies (including their brains), women with CAIS have had much less “masculinization” than the average 46,XX woman because their cells do not respond to androgens.
Moreover, the SRY gene can be translocated onto an X chromosome (so that a 46,XX person may develop along a typical masculine pathway), and there are dozens of genes on chromosomes other than the X and the Y that contribute to sexual differentiation. And beyond the genes, a person’s sex development can be significantly influenced by environmental factors (including the maternal uterine environment in which the fetus developed)."
Does having a Y chromosome make someone a man? | Intersex Society of North America
A lot of unintended harm happens when people assume a Y chromosome makes a person a boy or a man and the lack of a Y chromosome makes a person a girl or a woman. For example, one physician educator on our Medical Advisory Board had the challenging experience of trying to calm a 23-year-old...
