Solution
Core Logic
GIFT stands for Gamete Intra Fallopian Transfer. It is an in-vivo technique used to assist infertility. As the name implies, it involves transferring a gamete (specifically an ovum collected from a donor) directly into the fallopian tube of a female who cannot produce her own ovum, but can provide a suitable internal environment for fertilization and embryonic development.
Step 1: Analyzing Other Options
- Option 3 (Early embryo to uterus) describes IUT (Intra Uterine Transfer).
- Option 4 (Early embryo to fallopian tube) describes ZIFT (Zygote Intra Fallopian Transfer).
Step 2: Final Conclusion
Option 2 is the exact definition of GIFT.
Pattern Recognition
GIFT = Gamete (Ovum) -> Fallopian Tube. ZIFT = Zygote -> Fallopian Tube. IUT = Embryo -> Uterus.
