How sex determined in human

A sex-determination system is a biological system that determines the development of sexual characteristics in an organism.

Chromosomal sex is determined at the time of fertilization; a chromosome from the sperm cell, either X or Y, fuses with the X chromosome in the egg cell. Gonadal sex refers to the gonads, that is the testis or ovaries, depending on which genes are expressed.
