Gametogonium

Look up gametogonium in Wiktionary, the free dictionary.

Gametogonium (plural gametogonia) are stem cells for gametes located within the gonads. They originate from primordial germ cells, which have migrated to the gonads. Male gametogonia which are located within the testes during development and adulthood are called spermatogonium (plural spermatogonia). Female gametogonia, known as oogonium (plural oogonia), are found within the ovaries of the developing foetus and were thought to be depleted at or after birth. Spermatogonia and oogonia are classified as sexually differentiated germ cells.
