Question

In which of the following techniques, the embryos are transferred to assist those females who cannot conceive?

• A. ZIFT and IUT
• B. GIFT and ZIFT
• C. ICSI and ZIFT
• D. GIFT and ICSI

Hint:

ZIFT and IUT are the techniques in which embryos are transferred to assist those females who cannot conceive.

Answer 1

The Correct Option is A

To solve this question, we need to understand the fertilization techniques mentioned and identify which are used to help females who cannot conceive.

1. Key Concepts:
   • ZIFT (Zygote Intrafallopian Transfer): In ZIFT, after in vitro fertilization, the zygote (fertilized egg at the early stage) is placed into the fallopian tubes rather than the uterus.
   • IUT (Intrauterine Transfer): In this technique, embryos are transferred directly into the uterus.
2. Explanation of Options:
   • Option A - ZIFT and IUT: This is the correct option. Both ZIFT and IUT involve transferring embryos to aid females who cannot conceive. In ZIFT, the transfer is to the fallopian tube, while in IUT, it's to the uterus.
   • Option B - GIFT and ZIFT: GIFT (Gamete Intrafallopian Transfer) involves transferring gametes (sperm and egg) to the fallopian tubes. It is not related directly to embryo transfer.
   • Option C - ICSI and ZIFT: ICSI (Intracytoplasmic Sperm Injection) is a method to fertilize an egg, but it is not a method of embryo transfer.
   • Option D - GIFT and ICSI: As explained above, GIFT involves gametes and ICSI is for fertilization, not for transferring embryos.
3. Conclusion: The correct answer is ZIFT and IUT as these are both embryo transfer techniques, assisting women who cannot otherwise conceive naturally.
