Which of the following is wrongly matched ?

Options

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

Answer

To determine which of the reproductive health techniques is wrongly matched, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Techniques**: The techniques mentioned are:
- IUI (Intrauterine Insemination)
- GIFT (Gamete Intra Fallopian Transfer)
- ICSI (Intracytoplasmic Sperm Injection)
- ZIFT (Zygote Intra Fallopian Transfer)

2. **Analyze IUI**:
- **Definition**: IUI involves the artificial introduction of sperm into the female reproductive tract.
- **Match**: The description states that semen is collected from the husband or a donor and introduced into the vagina or uterus. This is correct.
- **Conclusion**: IUI is correctly matched.

3. **Analyze GIFT**:
- **Definition**: GIFT involves the transfer of gametes (sperm and ova) into the fallopian tubes.
- **Match**: The option states that it is the transfer of an embryo with more than 8 blastomeres into the fallopian tube, which is incorrect. GIFT actually involves the transfer of ova (not embryos) into the fallopian tubes.
- **Conclusion**: GIFT is wrongly matched.

4. **Analyze ICSI**:
- **Definition**: ICSI is a technique where a single sperm is injected directly into an ovum.
- **Match**: The description states sperm is directly injected into the ovum, which is correct.
- **Conclusion**: ICSI is correctly matched.

5. **Analyze ZIFT**:
- **Definition**: ZIFT involves the transfer of a zygote into the fallopian tube.
- **Match**: The option states that it is the transfer of an embryo up to the 8 blastomere stage into the fallopian tube, which is correct as ZIFT transfers the zygote at this stage.
- **Conclusion**: ZIFT is correctly matched.

### Final Answer:
The wrongly matched technique is **GIFT** (Gamete Intra Fallopian Transfer).
