Gonad
endocrine gland that produces the gametes of an organism / From Wikipedia, the free encyclopedia
A gonad is a gland that makes gametes and sex hormones. The male gonad is the testicle. Testicles make sperm cells. The female gonad is the ovary. Ovaries make egg cells.[1] Some animals have different gonads because they are hermaphroditic. They may have gonads such as the ovotestis. This is a gland that is similar to testicles and ovaries.[2][3]
