The success rate of artificial insemination is low, about 10-20%. For patients with indications, 3 IUIs are generally recommended. Most of the patients who are able to have a successful pregnancy can do so after 2-3 treatments. If the pregnancy is still not achieved after more than 6 times, the chances of success are low and other assisted reproductive medicine techniques are recommended. The success rate of IUI is affected by the patient’s own condition. If the couple is young, the woman’s fallopian tubes are open and the uterus is free of obvious pathology, and the husband’s semen is of good quality, the success rate of IUI is relatively high and may result in 2-3 successful pregnancies. However, if the woman herself has blocked fallopian tubes, endometrial lesions, etc., and the male sperm malformation rate is high, the success rate of artificial insemination is lower at this time. Further examination is needed, and then according to the examination results, symptomatic treatment of endometrial lesions, application of surgery to unblock the fallopian tubes or medical means to improve the quality of sperm to help improve the success rate of artificial insemination. In addition, the patient should choose a regular, professional hospital, where the doctor’s skills, equipment and other conditions are also important factors to ensure the success rate. If a woman is over 35 years old or has poor ovarian function, and there is no obvious effect after treatment, it is recommended to reduce the number of IUIs, and after talking with a professional doctor, other methods of pregnancy assistance with higher success rates, such as IVF, can be chosen.
