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. [1] gametes are an organism's reproductive cells, also referred to as sex cells

In both males and females, the production of sex cells involves meiosis, a type of cell division. Cells enter meiosis ii with haploid cells that contain two identical copies (sister chromatids) of each chromosome, and those are separated into two new cells by the end of meiosis ii Gamete cells, also known as sex cells, are the cells responsible for sexual reproduction A male gamete is called sperm (spermatozoa) and is a haploid cell formed through spermatogenesis
