In vitro fertilisation (IVF– test tube baby programme):
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 (with up to 8 blastomeres) into fallopian tube.
Intra Uterine Transfer (IUT): Transfer of embryos with more than 8 blastomeres into the uterus.
Embryo formed by in vivo fertilisation (fertilisation within the female) is also used for such transfer to assist those females who cannot conceive.
