The early embryos with upto blastomeres are transferred into the fallopian tube in one of the assisted reproductive technologies (ART). Identify the technique.

ZIFT

The correct answer is Option (2) → ZIFT 

A large number of couples all over the world including India are infertile, i.e., they are unable to produce children the couples could be assisted to have children through certain special techniques commonly known as assisted reproductive technologies (ART).

The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT–zygote intra fallopian transfer) and embryos with more than 8 blastomeres, into the uterus (IUT – intra uterine transfer), to complete its further development.Transfer of an ovum collected from a donor into the fallopian tube (GIFT – gamete intra fallopian transfer) of another female who cannot produce one, but can provide suitable environment for fertilisation and further development is another method attempted. Infertility cases either due to inability of the male partner to inseminate the female or due to very low sperm counts in the ejaculates, could be corrected by artificial insemination (AI) technique. In this technique, the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus (IUI – intra-uterine insemination) of the female.

Intra cytoplasmic sperm injection (ICSI) is another specialised procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum placed in a nutrient broth.The zygote or early embryo is later transferred by ZIFT in woman.
