We know that the material basis for pregnancy and childbirth is the egg and sperm. The egg is produced by the ovary of a woman. The ovary is located on both sides of the uterus in the pelvic cavity. It consists of two parts: the cortex and the medulla. The cortex is located in the ovary. The outermost layer is where follicles are concentrated. Due to various reasons, lesions may occur in the ovary, such as inflammation, tumors, etc. The lesions may occur on one side or both sides. In general, lesions on one side of the ovary do not have much effect on fertility. Such as ovarian cysts to reverse the side of the oophorectomy, and normal contralateral ovary, can also be normal ovulation. If the ovarian tumor is malignant, that is, ovarian cancer, ovarian cancer often involves the bilateral ovary, the doctor will not consider whether the patient has fertility requirements, remove the bilateral ovaries and uterus, that is, ovarian cancer radical surgery, thus completely lost her fertility .
