Question

Hysterectomy is a surgical removal of the uterus. Why would it be an advantage to leave the ovaries intact?

Answer 1

Though removal of ovary during hysterectomy can reduce the risk of developing ovarian cancer, but removal of ovary also deprives the body of a woman from getting the benefits of estrogen hormone secreted from ovary.

Removal of ovary is supposed to be associated with the beginning of menopause, increased blood pressure and development of heart disease. It also causes osteoporosis in women.

Estrogen regulates the activity of osteoblasts or bone forming cells. In absence of estrogen, osteoblasts can not produce bones effectively. On the other hand, the bone removing cells or osteoclasts continue to resorb bone. As a result osteoporosis occurs.

Estrogen also has  anti-inflammatory action and stimulates the production of antibodies by promoting B-call activation.
