Endometriosis is called benign “cancer”. It grows indefinitely and occurs as chocolate cysts on the ovaries. It causes infertility, miscarriage, painful intercourse, and menstrual pain. Women of childbearing age are at high risk for endometriosis, and its incidence has been on the rise in recent years. The occurrence of endometriosis often affects the reproductive function, leading to a significantly higher incidence of infertility, spontaneous abortion, and assisted reproductive assistance. Therefore, for the majority of women who have not had children and still have remaining requirements, paying attention to the diagnosis and treatment of endometriosis is an important prerequisite to ensure the hope of successful fertility in the future. First of all, laparoscopic reduction of ectopic foci is known as the gold standard of diagnosis and treatment, but the surgery, especially the ovarian coeliac debridement surgery, may pose a great threat to ovarian function, and ovarian hypofunction or even failure is a common cause of our infertility clinic, because the characteristic of endometriosis is that it is highly invasive to surrounding tissues and organs like a malignant tumor, and the demarcation between the cyst and the surrounding tissues is unclear, so causing surgical difficulties, great damage to surrounding tissues, and ovarian function that is more sensitive to various injuries often decreases significantly after surgery, shortening the life span of the patient’s ovaries and reducing their hopes for fertility. If the cyst is not too large, ruptured, torsional or of unclear nature, it is recommended to consider whether to operate after childbirth if you have the conditions to have children, so as to avoid irreversible ovarian damage and reduced fertility hopes; if you do not have the conditions to have children, it is recommended to consider drug conservative treatment as much as possible, according to your medical conditions and under the guidance of a professional doctor. If you do not have the conditions for fertility, it is recommended that you consider conservative medication as much as possible. Early childbirth is required after surgery. It is also hoped that the majority of obstetricians and gynecologists will try to preserve as much normal ovarian tissue as possible during surgery to preserve the patient’s reproductive function. The golden time for pregnancy after laparoscopy is six months. If you do not get pregnant after more than six months, it is recommended to see a professional infertility doctor early and early IVF is necessary if necessary. Secondly, pregnancy and breastfeeding are effective means of treating endometriosis, both for the purpose of and during treatment, as pregnancy inhibits ovarian function and amenorrhea, which stops the development of ectopic endometrium, but often it is difficult for such patients to get pregnant. Therefore, early formal medical consultation and early pregnancy under the guidance of a specialist. Once again, drug therapy, all drug therapy principle is to inhibit ovarian function, so that the body is in a low estrogen state, internal migration lesions may only be temporarily controlled, for those unmarried or temporarily childless patients, should be under the guidance of professional doctors to choose to choose the right drug therapy, the so-called suitable most mainly refers to the economic problems and the side effects of various drugs. GnRH-a is effective but expensive, and its long-term application for the general population is restricted. Other drugs such as norethindrone (gynecomastia tablets), methoprene (gynecomastia tablets), androgens, danazol and endometrium are not as effective as they could be if combined with treatment, but they are relatively inexpensive and should be chosen carefully under the guidance of a professional doctor.
