Which of the following is wrongly matched ?

Options

A. IUI - semen collected from husband or donor is artificially introduced either into the vagina or into the uterus
B. GIFT - transfer of embryos with more than 8 blastomeres into the Fallopian tube
C. ICSI - sperm directly injected into the ovum
D. ZIFT - transfer of embryos with upto 8 blastomeres into the Fallopian tube

Answer

To solve the question of which option is wrongly matched, we need to analyze each of the terms and their definitions related to assisted reproductive technologies.

### Step-by-Step Solution:

1. **Understanding IUI (Intrauterine Insemination)**:
- IUI involves the introduction of sperm into a woman's uterus during ovulation. This is done to increase the chances of fertilization.
- **Conclusion**: This match is correct.

2. **Understanding GIFT (Gamete Intrafallopian Transfer)**:
- GIFT involves the transfer of eggs (ova) from a donor to the fallopian tube of another female who is unable to produce eggs. This process allows for natural fertilization to occur in the fallopian tube.
- The statement mentions that "embryo is transferred with more than 8 blastomeres," which is incorrect because GIFT involves the transfer of gametes, not embryos.
- **Conclusion**: This match is incorrect.

3. **Understanding ICSI (Intracytoplasmic Sperm Injection)**:
- ICSI is a procedure where a single sperm is injected directly into an egg. This technique is used when there are issues with sperm motility or other factors affecting fertilization.
- **Conclusion**: This match is correct.

4. **Understanding ZIFT (Zygote Intrafallopian Transfer)**:
- ZIFT involves the transfer of a zygote (fertilized egg) into the fallopian tube. This is typically done when the zygote has already divided into several cells (more than 8 blastomeres).
- **Conclusion**: This match is correct.

### Final Answer:
Based on the analysis, the wrongly matched option is **GIFT** because it incorrectly states that embryos are transferred, whereas GIFT involves the transfer of gametes (ova).
