The basic procedure followed in the human reproductive system starts with developing the eggs for fertilization. Every month the eggs get mature, and at this point, if the couples complete the intercourse, then the sperm meets with the eggs and changes into an embryo.
Further, after two weeks of pregnancy, the test is done to know the result when it changes into an embryo. If the result is no, then the couple faces the problem of not fertilizing the eggs with sperm which is known as infertility.
There are many reasons why sperm do not get combined with eggs. As per the reasons, treatments are introduced. The IUI is the basic treatment completed by a catheter tool where the sperm will be inserted into a female uterus to complete the fertilization process.
