Solution
Sol. [Key Concept: ICSI — intracytoplasmic sperm injection]
Intra cytoplasmic sperm injection (ICSI) is a procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum.
ZIFT (Zygote intra fallopian transfer) involves transfer of the zygote or early embryos with upto 8 blastomeres into the fallopian tube.
GIFT (Gamete intra fallopian transfer) involves transfer of 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.
