Gametes are produced by gonads.
The gonad is the main gland responsible for producing reproductive cells (gametes). The gonads are known as the testes in males and the ovaries in females. The gonads are transient organs in some lower invertebrate groups (such as hydrozoans), but they are permanent in higher forms. One invertebrate, such as an oligochaete worm or a leech, can have both male and female gonads. Sponges lack distinct gonads; instead, amoebocyte clusters in the body wall give rise to reproductive cells. The gonads of echinoderms, such as starfish, are typically hanging from the radiating arms directly into the water.
