3D animation of how IUI works

IUI stands for Intrauterine Insemination.
It is an Artificial insemination, or AI, a process by which sperm is placed into the reproductive tract of a female for the purpose of impregnating the female by using means other than sexual intercourse or NI.

Video speaks clearer than words.
