The reasons for infertility could be physical, congential, diseases, drugs, immunological or psychological.
In this method, ova from the wife/donor and sperms from the husband/donor are collected and are induced to form zygote under simulated conditions in the laboratory. This is followed by Embryo transfer(ET). It is 2 types :
Zygote Intra Fallopian Transfer(ZIFT) : Transfer of zygote or early embryos into fallopian tube.
Intra Uterine Transfer(IUT) : Transfer of embryos with more than 8 blastomeres into the uterus.
Embryo formed by in vivo fertilisation is also used for such transfer to assist those females who cannot conceive.
