The test-tube baby programme employs which one of the following techniques

Options

A. Zygote intra fallopian transfer (ZiFT)
B. Intra cytoplasmic sperm injection (ICSI)
C. Intra uterine insemination (IUI)
D. Gamete intra fallopian transfer (GIFT)

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks which technique is employed in the test-tube baby program. The term "test-tube baby" typically refers to a method of assisted reproductive technology.

2. **Identifying the Techniques**: The options given are:
- A) Zygote Intrafallopian Transfer (ZIFT)
- B) Intracytoplasmic Sperm Injection (ICSI)
- C) Intrauterine Insemination (IUI)
- D) Gamete Intrafallopian Transfer (GIFT)

3. **Analyzing Each Technique**:
- **ZIFT**: This involves fertilizing an egg in a laboratory and then transferring the zygote into the fallopian tube.
- **ICSI**: This technique involves injecting a single sperm directly into an egg, usually used in conjunction with IVF.
- **IUI**: This is a simpler procedure where sperm is placed directly into the uterus, not involving a test tube.
- **GIFT**: This involves placing both eggs and sperm into the fallopian tubes, allowing fertilization to occur naturally.

4. **Identifying the Correct Technique**: Among these options, ZIFT is the technique that specifically involves the transfer of a zygote, which aligns with the concept of a "test-tube baby" program.

5. **Conclusion**: The correct answer is **Zygote Intrafallopian Transfer (ZIFT)**.
