Intrauterine insemination (IUI) is an assisted reproductive treatment in which sperm is taken from the semen and transferred to the uterus after washing by the desired catheter through a syringe. Its target population includes the patients who undergo infertility treatment by the IUI method and are not prohibited from using this product (listed in the limitations of using the device). The IUI catheter includes several components and parts. Each of these parts plays various roles. They include a Luer Lock hub to connect the catheter to the syringe, a very flexible inner tube to enter the sperm and guide it into the uterus, an outer tube to maintain and guide the inner tube, and a steel guiding tube for easier inserting of the catheter into the uterine space.  The vaginal entrance for a better view of the cervix is opened using a speculum, and the desired catheter at the specified size is inserted.  Then, the catheter is guided to the desired location using a metal tube mandrel. The mandrel is removed from the catheter inside. Then, the syringe containing the sperm is connected to the hub catheter. Then, the set of sperm is emptied through the catheter tube inside the uterus for insemination. Then, the catheter is removed from the patient's body.
