Patient: Bilateral ovarian chocolate cysts? I want to have children, but I have not been pregnant for 1 year after marriage, can I get pregnant after surgery? Answer: For patients who want to preserve their fertility, the purpose of conservative surgery is to remove the lesions, restore the normal anatomical relationship of the pelvis and improve the fertility function. However, the formation of different degrees of adhesions on the postoperative trauma is sometimes unavoidable. Clinically, endometriosis is classified into stages I-IV according to the severity of the disease, and the more severe the disease, the worse the prognosis. In general, about 30%-50% of patients with endometriosis are infertile, and about 50% of surgically treated patients are able to conceive spontaneously after surgery, and the pregnancy rate is highest in the first year after surgery. Another important clinical feature of endometriosis is the tendency of recurrence after surgery, especially in young patients, and once recurrence occurs, the chance of pregnancy after reoperation is even lower. Therefore, patients are advised to prepare for pregnancy as early as possible after surgery, preferably within one year after surgery. In some patients, pregnancy can be achieved through reproductive assisted techniques. Therefore, it is important to build confidence in the treatment of infertility in patients with endometriosis.
