Oophorectomy
Surgical removal of both ovaries, also called a bilateral oophorectomy (OH-uh-fuh-REK-tuh-mee), causes menopause right away.
A woman's periods will stop after this surgery, and her hormones drop quickly. She may immediately have strong menopausal symptoms, like hot flashes and diminished sexual desire.

A woman who has both ovaries removed at the same time that the hysterectomy is done has menopause right away. Having both ovaries removed is called a bilateral oophorectomy (OH-uh-fuh-REK-tuh-mee). Women who have this operation no longer have periods and may have menopausal symptoms right away. Because your hormones drop quickly, your symptoms may be stronger than with natural menopause. If you are having this surgery, ask your doctor about how to manage your symptoms.
