Answer

To answer the question "Which technique is used for test tube baby?", we can follow these steps:

### Step 1: Understand the Concept of Test Tube Baby
- A test tube baby refers to a baby conceived through assisted reproductive technology (ART), specifically through a process called in vitro fertilization (IVF).

### Step 2: Identify the Process of In Vitro Fertilization (IVF)
- In IVF, the fertilization of an egg by sperm occurs outside the body, typically in a laboratory setting. This is done in a glass container, hence the term "test tube baby".

### Step 3: Recognize the Stages of Embryo Development
- After fertilization, the fertilized egg (zygote) begins to divide and develop into an embryo. This can happen in a test tube or petri dish.

### Step 4: Understand the Transfer Techniques
- Once the embryo reaches a certain stage of development, it needs to be transferred back into the female's reproductive system. The two main techniques for this transfer are:
- **Zygote Intra-Fallopian Transfer (ZIFT)**: This is used when the embryo is at the zygote stage and is transferred to the fallopian tube.
- **Intrauterine Transfer (IUT)**: This is used when the embryo has developed further (usually more than 8 cells) and is transferred to the uterus.

### Step 5: Conclusion
- The technique specifically used for transferring the embryo in the context of a test tube baby is called **Intrauterine Transfer (IUT)**.

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