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

GIFT, or Gamete Intrafallopian Transfer, is a procedure where an ovum from a donor is placed into the fallopian tube of another female. In GIFT, both the ovum (egg) and sperm are introduced directly into the fallopian tube, facilitating natural fertilization within the body. This technique is distinguished by the direct placement of gametes internally.

A concise comparison of related methods:

Method	Explanation
IUI	Intrauterine Insemination: sperm is deposited directly into the uterus.
ICSI	Intracytoplasmic Sperm Injection: a single sperm is injected into an egg during laboratory procedures.
GIFT	Gamete Intrafallopian Transfer: eggs and sperm are transferred into the fallopian tube.
ZIFT	Zygote Intrafallopian Transfer: a fertilized zygote is placed into the fallopian tube.

Of these techniques, GIFT is unique in that it involves the transfer of the ovum directly into the fallopian tube without prior fertilization.
