In which 'Assisted Reproductive Technology' (ART), Test-tube Baby' procedure is applied?

Options

A. Gamete Intrafallopian Transfer (GIFT)
B. Intra Cytoplasmic Sperm Injection (ICSI)
C. In Vitro Fertilisation and Embryo Transfer (IVFET)
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the specific Assisted Reproductive Technology (ART) in which the "test-tube baby" procedure is applied.

2. **Identifying ART Options**: The options provided are:
- A) Gamete Intra-Fallopian Transfer (GIFT)
- B) Intracytoplasmic Sperm Injection (ICSI)
- C) In Vitro Fertilization and Embryo Transfer (IVF-ET)

3. **Analyzing Each Option**:
- **Option A: Gamete Intra-Fallopian Transfer (GIFT)**: This technique involves removing an egg from the female body and placing it into the fallopian tube along with sperm. This method does not involve fertilization in a test tube, so it is not the correct answer.

- **Option B: Intracytoplasmic Sperm Injection (ICSI)**: In this procedure, a single sperm is injected directly into the egg using a micropipette. While this is a form of ART, it is not specifically referred to as the "test-tube baby" procedure since the fertilization occurs within the egg and not in a test tube.

- **Option C: In Vitro Fertilization and Embryo Transfer (IVF-ET)**: This method involves fertilizing the egg and sperm outside the body in a laboratory setting (the "test tube"). The fertilized egg (embryo) is then transferred to the uterus. This is the procedure commonly referred to as the "test-tube baby" procedure.

4. **Conclusion**: Based on the analysis, the correct answer is **Option C: In Vitro Fertilization and Embryo Transfer (IVF-ET)**, as it directly involves the test-tube baby procedure.

**Final Answer**: In Vitro Fertilization and Embryo Transfer (IVF-ET).
