In females, the process of oogenesis occurs in the ovaries. Primordial germ cells differentiate into primary oocytes during fetal development. These primary oocytes remain arrested in prophase I until puberty, when they resume meiosis to form secondary oocytes and eventually mature ova. In males, spermatogenesis takes place in the seminiferous tubules of the testes. Spermatogonia undergo mitotic and meiotic divisions to produce mature spermatozoa.
