Does menstruation change after removal of one ovary?

Yes, menstruation can change after the removal of one ovary, a procedure known as oophorectomy. The remaining ovary typically continues to produce hormones and release eggs, so many women may not notice significant changes in their menstrual cycles. However, some might experience irregular periods or changes in cycle length due to hormonal fluctuations. Additionally, if the remaining ovary fails to function adequately, menopause may occur earlier than expected.
