The technique of direct introduction of gametes into the oviduct is called

Options

A. Artificial insemination
B. ICSI
C. GIFT
D. IVE-ET

Answer

To solve the question regarding the technique of direct introduction of gametes into the oviduct, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the name of the technique used for the direct introduction of gametes into the oviduct.

2. **Identify the Techniques**: The options provided are:
- Artificial insemination
- ICSI (Intracytoplasmic Sperm Injection)
- GIFT (Gamete Intra Fallopian Transfer)
- IVF (In Vitro Fertilization) and ET (Embryo Transfer)

3. **Analyze Each Option**:
- **Artificial Insemination**: This technique involves placing sperm into the female reproductive tract but does not directly introduce gametes into the oviduct. Therefore, this option is incorrect.
- **ICSI**: This is a specialized form of IVF where a single sperm is injected directly into an egg. It does not involve the direct introduction of gametes into the oviduct, so this option is also incorrect.
- **GIFT**: This technique stands for Gamete Intra Fallopian Transfer. It involves the direct transfer of both sperm and eggs into the fallopian tubes (oviduct), which matches the requirement of the question.
- **IVF and ET**: In this process, fertilization occurs outside the body, and then the embryo is transferred to the uterus, not the oviduct. Thus, this option is incorrect.

4. **Select the Correct Answer**: Based on the analysis, the correct answer is **GIFT (Gamete Intra Fallopian Transfer)**, as it is specifically designed for the direct introduction of gametes into the oviduct.

### Final Answer:
The technique of direct introduction of gametes into the oviduct is called **GIFT (Gamete Intra Fallopian Transfer)**.
