Oophorectomy is the procedure of removing the ovaries. The procedure involving removal of both ovaries is called bilateral oophorectomy and the procedure involving removal of only one ovary is termed as unilateral oophorectomy. This is the most sought-after treatment option for ovarian cancer or other ovarian abnormalities. Sometimes, the procedure is done on the women who have an elevated risk of hereditary cancer, and is further as a precaution for preventing ovarian or fallopian tube cancer. Researchers have proved that the ovarian surgery helps improve the survival ratio of the BRCA mutation carriers. But since the ovaries are being removed, the treatment causes immediate surgical menopause.
