Which of the following is wrongly matched?

Options

A. IUI -Semen collected from husband ordonor 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 determine which of the following options is wrongly matched, we need to analyze each option related to assisted reproductive technologies (ART).

1. **Intrauterine Insemination (IUI)**:
- IUI involves the insertion of sperm directly into the female reproductive tract (either the vagina or uterus) to facilitate fertilization. This is correctly matched as it is a recognized ART procedure.

2. **Gamete Intra-Fallopian Transfer (GIFT)**:
- GIFT involves the transfer of gametes (sperm and eggs) directly into the fallopian tubes. The statement provided mentions "Transfer of embryo with more than 8 blastomeres into the Fallopian Tube," which is incorrect because GIFT does not involve transferring embryos; it involves transferring gametes. Therefore, this option is wrongly matched.

3. **Intracytoplasmic Sperm Injection (ICSI)**:
- ICSI is a procedure where a single sperm is injected directly into an ovum (egg). This is correctly matched as it accurately describes the ICSI procedure.

4. **Zygote Intra-Fallopian Transfer (ZIFT)**:
- ZIFT involves transferring a zygote (fertilized egg) into the fallopian tube. The statement mentions "Transfer of embryo with up to 8 blastomeres," which is correct for ZIFT, as it refers to transferring a zygote at an early developmental stage.

Based on the analysis, the option that is wrongly matched is **Option 2: GIFT**.

### Step-by-Step Solution:
1. Identify the terms related to assisted reproductive technologies.
2. Analyze the definition of each term.
3. Compare the definitions with the statements provided.
4. Identify any discrepancies or incorrect matches.
5. Conclude which option is wrongly matched.
