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.

gonad

a sex gland; a gamete-producing gland; the ovary in the female and the testis in the male.
The ovary produces the ovum and the testis produces the spermatozoon. In addition, the gonads secrete hormones that influence the development of the reproductive organs and the physical traits that differentiate males from females, such as a crest and body form and size (the secondary sex characters). The hormones produced by the ovary include estrogen and progesterone. The principal hormone produced by the testis is testosterone.

hermaphroditic g's
these gonads vary widely between combinations of male and female tissues in an ovotestis, of which there may be one or two, to a testicle on one side and an ovary on the other.
indifferent gonad
the primordial stage of the embryonal gonad, before differentiation into a male or female organ.
