This is literally deﬁned as ‘deprivation of the power of generation’. In practical terms this involves surgical removal of both OVARIES, or both testicles (see TESTICLE). Such an operation is most commonly associated with the treatment of malignant lesions. In women who have reached the menopause, bilateral oophorectomy is routinely performed during HYSTERECTOMY, especially in cases of uterine carcinoma, and is usually performed when removing an ovarian tumour or malignant cyst. It is essential that the surgeon discusses with a woman before an operation when it might prove beneﬁcial to remove her ovaries in addition to carrying out the main procedure. In men, orchidectomy is routine for testicular tumours, and is sometimes carried out when treating prostatic cancer.
