What is intrauterine insemination? Artificial insemination is a technique in which sperm is placed into the female reproductive tract through non-coital means to conceive her. The most common clinical method of IUI is intrauterine insemination (IUI). Intrauterine insemination (IUI) involves washing and processing semen, taking 0.3 ml of the most viable sperm and injecting it into the uterine cavity through a catheter during ovulation of the female partner. IUI can be performed during a natural cycle or during an ovulation-promoting cycle where more than 2 eggs may be expelled, leading to an increased incidence of multiple pregnancies and the development of a number of complications such as ovarian hyperstimulation syndrome. Who can choose intrauterine insemination? Intrauterine insemination (IUI) is an option for infertile couples with at least one intact fallopian tube in the female partner, mild weak sperm in the male partner, cervical factors in the female partner, ovulatory dysfunction or unexplained infertility in both partners, preferably before or within one day after ovulation. Vaginal ultrasound is used to monitor follicle growth to determine the timing of the IUI procedure. IUI is performed once per cycle. What do I think about the semen analysis test results? The main parameters in the semen test report are sperm density, sperm motility and viability, semen volume, liquefaction time and acidity, and sperm malformation rate. If the test results are within the normal range, it indicates that the man has normal fertility; if some of the parameters are not within the normal range, it does not necessarily mean that he cannot have children. The male partner should undergo a semen test when the infertile couple is seen. The semen test should be performed 3-7 days after intercourse or seminal emission, and the semen should be retrieved by masturbation. For assisted reproduction treatment, the male partner is required to retain semen by masturbation under sterile conditions.
