Options

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

Answer

To solve the question, "In which of the following assisted reproductive technology is sperm inserted into the egg with the help of a microscopic needle?" we will analyze the options provided and identify the correct one.

### Step-by-Step Solution:

1. **Understand Assisted Reproductive Technologies (ART)**:
- ART refers to medical procedures used to address infertility. These technologies assist couples who are unable to conceive naturally.

2. **Review the Given Options**:
- A) GIFT (Gamete Intrafallopian Transfer)
- B) ZIFT (Zygote Intrafallopian Transfer)
- C) ICSI (Intracytoplasmic Sperm Injection)
- D) IVF (In Vitro Fertilization)

3. **Analyze Each Option**:
- **GIFT**: Involves placing both sperm and eggs into the fallopian tubes, allowing fertilization to occur naturally inside the body.
- **ZIFT**: Involves fertilizing the egg outside the body and then placing the zygote into the fallopian tube.
- **IVF**: Involves fertilizing the egg outside the body and then transferring the resulting embryo into the uterus, but it does not specifically involve a microscopic needle.
- **ICSI**: This technique specifically involves using a microscopic needle to inject a single sperm directly into the cytoplasm of an egg, which is crucial for cases where sperm motility is low.

4. **Identify the Correct Answer**:
- Since the question specifically asks for the technology where sperm is inserted into the egg using a microscopic needle, the correct answer is **C) ICSI**.

### Final Answer:
C) ICSI (Intracytoplasmic Sperm Injection)
