Sperm is the male reproductive cell , or gamete , in anisogamous forms of sexual reproduction forms in which there is a larger, "female" reproductive cell and a smaller, "male" one. Animals produce motile sperm with a tail known as a flagellum , which are known as spermatozoa , while some red algae and fungi produce non-motile sperm cells, known as spermatia. Sperm cells form during the process known as spermatogenesis , which in amniotes reptiles and mammals takes place in the seminiferous tubules of the testes.
