If the tubes are blocked with normal ovarian function, the success rate is usually relatively high. Usually, despite the existence of tubal blockage, normal ovarian function is still able to secrete progesterone and estrogen, so the success rate of IVF is still relatively high. If there are problems such as decreased ovarian function and endometrial abnormality in addition to tubal blockage, the ovarian corpus luteum function will be less supportive and the endometrial lining will be less tolerant, which will lead to a relatively low IVF success rate. It is recommended that women should have an early checkup in preparation for IVF to determine whether their organism meets the criteria for the procedure, to clarify the riskiness of the procedure, and to follow the doctor’s instructions to have regular review in the hospital. It is recommended that both husband and wife during the preparation period should quit smoking and drinking, develop good living habits, and not stay up late. Moderate exercise to maintain good health, to avoid prolonged exposure to radiation or pollution in the environment, to get out of the toxic and harmful work environment; maintain a happy mood; avoid heavy physical labor.
