IPA: /ɔːrˈkiːɛk.tə.mi/
KK: /ɔrˈkiːɛkˌtɑːmi/
A surgical procedure to remove one or both testicles from the body.
The doctor recommended an orchiectomy to treat the patient's condition.
Orchiectomy is formed from "orchis" (from Greek "orchis", meaning testicle) and "-ectomy" (from Greek "ektomē", meaning excision or removal). The word refers to the surgical removal of one or both testicles.
Think of 'orchis' which relates to testicles and '-ectomy' meaning removal — this helps you remember that orchiectomy is the removal of testicles.
