'perigonal' originates from Greek, specifically the word 'perigonios,' where 'peri-' meant 'around' and 'gonos' meant 'seed' or 'offspring'.

'perigonios' transformed into the Latin word 'perigonus,' and eventually became the modern English word 'perigonal'.

Initially, it meant 'around the seed or offspring,' but over time it evolved into its current meaning of 'relating to or situated around a gonad or reproductive organ'.
