Intrauterine insemination (IUI) also called, artificial insemination, is one of the most cost-efficient and effective infertility treatments of modern times. It is an artificial reproductive technique where the women's uterus is artificially introduced to the male sperms with the help of a flexible tube. Once the male sperm is separated and washed from the semen ejaculation, it is injected deep inside the uterus, close to the ovum to facilitate fertilization. This process of IUI is painless and only takes a few minutes.
