Their primary purpose is to fuse during fertilization, combining their genetic instructions to initiate the development of a new, genetically distinct individual Typically contains half or a reduced number of chromosomes compared to a somatic cell The formation of sex cells is a central part of human reproduction
In fertilization, an egg cell and a sperm cell combine
These sex cells are also called reproductive cells or gametes Sperm cells are produced in men's testicles and egg cells are produced in women's ovaries Sex cells are different from other cells in one special way Put simply, they only have one half of the total amount.

From the time of puberty on, men make sex cells (in the form of sperm cells) continuously In contrast, by the time a woman is born, she has made all of the eggs that she will ever have As she reaches puberty, the eggs begin to develop and get released, and this process continues until menopause In both males and females, the production of sex cells involves meiosis, a type of cell division.
