Question

ZIFT is transfer of
A. Zygote into fallopian tube
B. Embryo into uterus
C. Mixture of sperms and ova into fallopian tube
D. Mixture of sperms and ova into the uterus.

Answer 1

Hint: ZIFT a technique to overcome inability of couples to conceive or produce children. It is an In vitro fertilisation technique and part of a test tube baby program in which eggs and sperm are made fertilised in the laboratory under simulated conditions i.e. similar conditions to produce embryo which is then transferred to mother depending on the stage it is transferred and part of reproductive system it is transferred.

Complete answer:
Option -A- Zygote into fallopian tube
After in vitro fertilisation, embryo or zygote upto 8 blastomeres is transferred into the fallopian tube for its further development. It is a technique called ZIFT i.e. zygote into a fallopian tube.
Option -B- Embryo into uterus
After in vitro fertilisation, embryo more than 8 blastomeres is then transferred to the uterus for its further development, a technique called IUT i.e. intrauterine transfer.
Option -C- Mixture of sperms and ova into fallopian tube
It is a technique of in vivo fertilisation called as GIFT i.e. Gamete Intrafallopian Transfer. In this technique sperm and ova are mixed and fertilisation does not occur and introduced into fallopian tube of mother who can provide suitable environment for its fertilisation and further development
Option -D- Mixture of sperms and ova into uterus
It is a technique of in vivo fertilisation or may be called as IntraCytoplasmic Sperm Injection. Im this sperm is injected into ova in the laboratory and embryo within one to two days or this mixture is introduced into the uterus.

So, the correct answer to this question is option “A” Zygote into a fallopian tube.

Note: Reproductive health is a serious concern these days and to overcome the problem of infertility or unable to conceive many techniques which are mentioned above are adopted commonly known as Assisted Reproductive Technologies (ART).
