The gonad is the organ that makes gametes. Gametes are haploid germ cells. For example, sperm and ovum|egg cells are gametes. In vernacular use, gonads is slang for testicles. The usage of such is similar to "balls." As such, in a time when society is allowing more women to reach levels of power, one can replace the vernacular saying "He's got balls" with the gender-neutral "They've got gonads". Gonads start developing as a common anlage, and only later are differentiated to male or female sex organs. The SRY gene, located on the Y chromosome and encoding the testis determining factor, decides the direction of this differentiation.
