Ovarian cysts may have no effect after surgery, and some may affect fertility, depending on the nature of the cysts and whether or not the ovaries are removed by surgery. 1. Benign cysts: If the ovarian cysts are benign cysts, such as corpus luteum cysts or benign teratomas of the ovary. If the cyst has not ruptured and there is no torsion of the tip. The surgery only removes the cyst, not the ovary. Generally, the surgery will not have adverse effects on the ovarian function of women, and the ovarian function will return to normal in about 1 to 2 months after the surgery. 2. Ovarian malignant tumor: If the ovarian cyst is a malignant tumor, the surgery will require the removal of both ovaries and uterus, which will affect the fertility function of women and lead to infertility. 3. Remove one side of the ovary: some women have benign ovarian cysts, but the cysts are relatively large and have undergone torsion. During surgery, one ovary is removed. The removal of one ovary in fertile women usually has little effect on their fertility. After 1 to 2 months, the other ovary will resume normal ovulation. Patients who need to undergo surgery for ovarian cysts are advised to consult a doctor in a timely manner, complete the relevant examinations, identify the cause of the disease and formulate an individualized treatment plan under the guidance of a professional doctor. If you feel unwell after surgery, it is recommended that you consult a doctor promptly.
