Hysterectomy versus hysterectomy plus oophorectomy for premenopausal women.

Prophylactic oophorectomy alongside hysterectomy in premenopausal women is common. The decision to remove or conserve the ovaries is often based on the perceived risk for ovarian cancer and the need for other additional gynaecological surgical interventions. The benefits or harms of prophylactic bilateral oophorectomy at the time of hysterectomy in premenopausal women are unknown.
