(C) ICSI (Intra Cytoplasmic Sperm Injection) is a specialized procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum placed in a nutrient
broth. GIFT (Gamete Intra Fallopian Transfer) is a method to transfer an ovum collected from a donor into the Fallopian tube of another female who cannot produce one but can provide suitable environment for fertilization and further development.
ZIFT (Zygote Intra Fallopian Transfer) is a method (similar to fn Vitro fertilization and embryo transfer in which the zygote (early embryo) up to 8 blastomeres is transferred directly into the Fallopian tube.
