Ovarian cysts do not require removal of the ovaries. Ovaries are very important to women. If one ovary is completely removed, although there is still another ovary, if it is the other ovary that loses function or develops cysts, it will cause a lot of confusion to the woman and she will experience early menopause. Therefore, clinically, surgery for ovarian cysts can be performed by simply peeling off the cyst and then suturing the remaining ovarian tissue. This will preserve a portion of the ovarian tissue from destruction and allow the ovaries to maintain normal body estrogen and progesterone and normal menstruation. In addition, the chances of recurrence are still very high, especially in the case of chocolate cysts, once the ovarian cysts are reviewed regularly after surgery.
