Oophorectomy is the term used to refer to any surgical procedure that entails the removal of one ovary or both ovaries, be it done through an open surgical procedure or through a laparoscopic procedure (use of probes with a camera at the end of the tube to help visualize the abdomen with a minimal incision).
This type of operation is done either as a definitive (curative) type of treatment or mainly for prophylaxis ( pre-emptive) treatment.
