Artificial insemination is popular among the infertility population because it is safe, convenient and closer to the natural process of pregnancy. However, compared to IVF, the success rate is not as high as we think, so how can we improve the success rate of IUI? To talk about how to improve the success rate, it is important to first understand the process of artificial insemination. Artificial insemination refers to the process of taking the male semen out of the body, optimizing it and then injecting it directly into the female reproductive tract through an artificial insemination tube before and after ovulation, so that the sperm and egg can be combined naturally to achieve the purpose of making the woman pregnant and fertile. The success rate of IUI is closer to natural conception, around 10%-15%, which is lower than the 40-60% success rate of IVF. The following points can improve the success rate of artificial insemination: 1. suitable age and open fallopian tubes Successful conception depends on good fertility, female patients over 35 years of age, their fertility can be said to be plummeting, even through assisted reproductive technology to help conceive, but also can not change the general trend, the older the age, the lower the success rate of artificial insemination. In addition, the prerequisite for artificial insemination is the patency of the fallopian tubes, which requires active cooperation between the patient and the doctor, taking a good medical history, doing a good pre-operative examination and, if necessary, performing a fallopian tube imaging to determine whether artificial insemination is necessary. The quality of male sperm is directly proportional to the success rate of artificial insemination. In the process of artificial insemination, male sperm will be optimized in the laboratory, but it does not essentially change the quality of sperm, but is only the process of selecting the best of the best. If a man has normal semen quality and is infertile only because he is unable to have intercourse due to sexual dysfunction and other reasons, the success rate of performing IUI is significantly higher than that of a patient with a problematic semen quality. Therefore, it is necessary to do a good examination before performing artificial insemination. The doctor will determine whether the patient can do artificial insemination according to his condition, and at the same time, it is also necessary to do a good job in daily life maintenance before doing assisted conception to ensure the quality of sperm. 3.Find the right time for artificial insemination One of the keys to improve the success rate of artificial insemination is to choose the exact time of insemination: artificial insemination is most likely to be successful from 48 hours before ovulation to 12 hours after ovulation. Usually the fertility doctor will monitor the follicles and the development of the endometrium through ultrasound and combine it with hormone levels to help determine the date of ovulation and arrange an IUI around the time the woman ovulates. 4.Mind Finally, it is also necessary to maintain a good mind and avoid anxiety. Patient psychological factors can also affect the success rate of artificial insemination. Patient tension and anxiety may cause certain effects on the female reproductive endocrine system, thus affecting the result of conception.
