Question

The test-tube Baby programme employs which one of the following techniques
A.Intra cytoplasmic sperm injection(ICSI)
B.Gamete intra fallopian transfer(GIFT)
C.Intrauterine insemination(IUI)
D.Zygote intra fallopian transfer(ZIFT)

Answer 1

The test-tube baby programme refers to the process of in vitro fertilization and embryo transfer. It is the type in which the sperm and the oocyte fertilization take place outside the female body. After the successful fertilization and development of embryo it is transferred back to the fallopian tube of a body.

Complete answer:
In vitro fertilization method, popularly known as test tube baby programme, in which ova from the female and sperms from the male are collected and are induced to form zygote under simulated conditions in the laboratory.
ZIFT is a method used to treat infertility in which an egg fertilized in vitro outside the body is placed into a women’s Fallopian tube oviduct. It is an assisted reproductive procedure similar to IVF and embryo transfer the difference being that zygote pre-embryo is transferred into the Fallopian tube instead of the uterus.

Intra cytoplasmic sperm injection is the process to treat the male infertility. It involves the injection of a single sperm directly into a mature egg of a body. Whereas in Gamete intra fallopian transfer (GIFT), sperm and eggs gametes are put in the fallopian tube where the fertilization takes place in the female's body itself.
Intrauterine insemination is a type of artificial insemination in which sperm that have been washed and concentrated are placed directly in your uterus around the time the ovary releases one or more eggs to be fertilized.

Hence, the correct answer is option (D)

Note: The Test tube baby programme is the in vitro fertilization, a process of fertilization where an egg is combined with sperm outside the body, and kept under a critical environment and released in the female body after complete fertilization and formation of embryo.
