Which technique is used for test tube baby ?

Options

A. IUT
B. GIFT
C. Amniocentesis
D. IUI

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the technique used for a test-tube baby, which refers to assisted reproductive technologies.

2. **Reviewing the Options**: The options provided are:
- A) IUT (Intrauterine Transfer)
- B) GIFT (Gamete Intra-Fallopian Transfer)
- C) Aminocentesis
- D) IUI (Intrauterine Insemination)

3. **Analyzing Each Option**:
- **Option A: IUT (Intrauterine Transfer)**: This technique involves transferring an early embryo into the uterus. It is a key step in the process of creating a test-tube baby.
- **Option B: GIFT (Gamete Intra-Fallopian Transfer)**: This involves transferring eggs (ova) from a donor into the fallopian tube of a woman who cannot produce eggs. It is not specifically for test-tube babies but rather for natural fertilization.
- **Option C: Aminocentesis**: This is a procedure for prenatal diagnosis and is used for sex determination of the fetus. It is not related to the conception process and is not used for test-tube babies.
- **Option D: IUI (Intrauterine Insemination)**: This technique involves placing sperm directly into the uterus but does not involve creating embryos in a lab, which is central to the test-tube baby process.

4. **Conclusion**: Based on the analysis, the technique specifically used for creating a test-tube baby is **IUT (Intrauterine Transfer)**.

### Final Answer:
The technique used for a test-tube baby is **IUT (Intrauterine Transfer)**.
