Intra Cytoplasmic Sperm Injection (ICSI): It is a specialised form of in vitro fertilisation (IVF) that involves the injection of a single sperm directly into a mature egg to form embryo.

Intra Uterine Insemination (IUI): The semen with sperm collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus.

Intra Uterine Transfer (IUT): The embryo with more than 8 blastomeres is inserted into uterus to complete its further development.

Gamete Intra Fallopian Transfer (GIFT): It is a technique which transfers an ovum collected from a donor into the fallopian tube of another female who cannot produce one, but can provide suitable environment for fertilisation.

Zygote Intra Fallopian Transfer (ZIFT): It is the transfer of the zygote or early embryo (with upto 8 blastomeres) into the fallopian tube.
