gon(o)- Also gonado-.

Sexual; reproductive.

[Greek gonos, semen, seed, generation.]

A gonad (see -ad1) is an organ such as a testis or ovary that produces mature germ cells; in invertebrates, a gonopore is an opening through which eggs or sperm are released; gonorrhoea (US gonorrhea) (Greek rhoia, flux) is a contagious infection of the genital tract caused by a bacterium called a gonococcus. The form gonado derives from gonad by adding the linking vowel -o-; an example is ex>gonadotrophin (Greek trophē, nourishment), a hormone secreted by the pituitary which stimulates the action of the gonads.
