Question

The test-tube baby programme employs which one of the following techniques?

• A. Intra cytoplasmic sperm injection (ICSl)
• B. Intra uterine insemination (IUI)
• C. Gamete intra Fallopian transfer (GIFT)
• D. Zygote intra Fallopian transfer (ZIFT)

Answer 1

Answer: (D)

Zygote intra Fallopian transfer (ZIFT)

Answer 2

In in vitro fertilization method, popularly known as test tube baby programme, ova from the wife/ donor (female) and sperms from the husband/donor (male) are collected and are induced to form zygote under simulated conditions in the laboratory. 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.
