IUI is medically known as intrauterine insemination, which utilizes artificial methods to inject semen into the uterine cavity, with indications such as sexual dysfunction and ovulation disorders, and contraindications such as bad habits and genetic disorders. Intrauterine insemination is a commonly used type of assisted reproduction in artificial insemination, which mainly uses artificial methods to inject male semen into the female uterine cavity to make the female successfully conceive. Intrauterine insemination is suitable for couples with male sexual dysfunction, weak spermatozoa, and female ovulation disorders, endometriosis, and other diseases. However, intrauterine insemination is not available for those who have bad habits, genetic diseases, serious physical diseases, mental and psychological disorders, or inflammation of the reproductive tract. Although the technology of intrauterine insemination is relatively mature, its success rate cannot be generalized. Therefore, for those who choose intrauterine insemination, they need to be psychologically prepared in advance, do not need to have too much psychological pressure, and actively cooperate with the doctor.
