gonad

 [go´nad]
a gamete-producing gland; the ovary in the female or the testis in the male. Called also sex gland. adj., adj gonad´al, gonad´ial. The ovary produces the oocyte (ovum) and the testis produces the spermatozoon. In addition, the gonads secrete hormones that influence the development of the reproductive organs at puberty, and they control other physical traits that differentiate men from women (secondary sex characters), such as pitch of the voice and body form and size. The hormones produced by the ovary include estrogen and progesterone. The principal hormone produced by the testis is testosterone.
