Question

The method where an ovum is transferred from a donor into the fallopian tube of another female is:

• A. IUI
• B. ICSI
• C. GIFT
• D. ZIFT

Answer 1

The Correct Option is C

The process of transferring an ovum from a donor into the fallopian tube of another female is called GIFT, which stands for Gamete Intrafallopian Transfer. In GIFT, the ovum (egg) and sperm are directly placed into the fallopian tube to encourage fertilization naturally within the body. This method differs from others as it involves the direct introduction of gametes into the body. 

Here is a brief comparison of the options provided:

Method	Explanation
IUI	Intrauterine Insemination; sperm is placed directly into the uterus
ICSI	Intracytoplasmic Sperm Injection; a single sperm is injected into an egg in a lab
GIFT	Gamete Intrafallopian Transfer; egg and sperm are transferred into the fallopian tube
ZIFT	Zygote Intrafallopian Transfer; a fertilized zygote is placed into the fallopian tube

Among these methods, only GIFT involves transferring the ovum directly into the fallopian tube without prior fertilization.

Answer 2

• GIFT (Gamete Intrafallopian Transfer) is a method where an ovum (egg) is retrieved from a donor and then transferred into the fallopian tube of another female, where fertilization can occur naturally.

Other options:

• IUI (Intrauterine Insemination): Involves placing sperm into the uterus, not the ovum into the fallopian tube.
• ICSI (Intracytoplasmic Sperm Injection): Involves the injection of a single sperm directly into an egg, generally in vitro, for fertilization.
• ZIFT (Zygote Intrafallopian Transfer): Involves placing a fertilized egg (zygote) into the fallopian tube, not an ovum.

Thus, GIFT is the correct answer.
