The method of directly injecting a sperm into ovum in assisted reproductive technology is called

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of a specific method in assisted reproductive technology where sperm is directly injected into an ovum.

2. **Identifying the Technique**: In assisted reproductive technology, there are various techniques used to facilitate fertilization. One such method involves the direct injection of sperm into the ovum.

3. **Describing the Process**: This method involves using a pipette to hold the ovum and an injection to insert the sperm directly into the cytoplasm of the ovum. This is crucial in cases where there are issues with sperm count or quality.

4. **Recognizing Related Conditions**: The technique is particularly useful in cases of oligospermia (low sperm count) or azoospermia (absence of sperm), where traditional fertilization methods may not be effective.

5. **Eliminating Incorrect Options**:
- **Gamete Intrafallopian Tube Transfer (GIFT)**: This is not the correct answer as it involves transferring gametes to the fallopian tubes rather than direct injection into the ovum.
- **Zygote Intrafallopian Tube Transfer (ZIFT)**: This involves transferring a zygote, which is not relevant to the question since it specifically mentions sperm and ovum.
- **Embryonic Transfer**: This method involves placing embryos into the uterus, which does not fit the description of injecting sperm into an ovum.

6. **Final Answer**: The correct term for the method of directly injecting sperm into the ovum is **Intracytoplasmic Sperm Injection (ICSI)**.
