Spermatogenesis – spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells.
Oogenesis – oogenesis is the process by which the female gametes, or ova, are created. The female gamete is called an ovum. Sometimes people will refer to female gametes as eggs, but the term egg can include more than one stage of development, and the definition of an egg also changes depending on the type of organism.
