The highly sophisticated procedure of directly injecting a sperm into an egg is called

Options

A. ICSI
B. ZIFT
C. GIFT
D. AI

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of a sophisticated procedure that involves directly injecting a sperm into an egg.

2. **Identifying the Options**: The options provided are:
- A) ICSI
- B) ZIFT
- C) GIFT
- D) AI

3. **Analyzing Each Option**:
- **A) ICSI (Intracytoplasmic Sperm Injection)**: This is a technique where a single sperm is injected directly into the cytoplasm of an egg (ovum). This method is used in cases of male infertility and is performed in vitro (outside the body).
- **B) ZIFT (Zygote Intrafallopian Transfer)**: In this procedure, eggs are fertilized in the lab and then the resulting zygote (early embryo) is transferred to the fallopian tube.
- **C) GIFT (Gamete Intrafallopian Transfer)**: This involves transferring both sperm and eggs into the fallopian tube, allowing fertilization to occur inside the body.
- **D) AI (Artificial Insemination)**: This technique involves introducing sperm into the female reproductive system without direct injection into the egg.

4. **Determining the Correct Answer**: The procedure that involves directly injecting a sperm into an egg is ICSI. Therefore, the correct answer is **A) ICSI**.

5. **Conclusion**: The highly sophisticated procedure of directly injecting a sperm into an egg is called **Intracytoplasmic Sperm Injection (ICSI)**.
