There are many forms of VIF and each forms are made for different purposes. basically, you just extract a female egg and a sample of the male sperm, bad sperm can be separated via by adding specific chemicals. The sperm will then be transferred into the egg and the egg is transferred into the women. (This is ICSI) There are other forms under the category of IVF but this is one of the example. (ICSI only deals with male infertility)
