In vernacular use, gonads is slang for testicles. The usage of such is similiar to "balls." As such, in an era where more women are reaching levels of power, one can replace the vernacular saying "He's got balls" to the gender neutral "They've got gonads."

Gonads start developing as a Jake Martin 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.
