The assisted reproductive technology which involves the transfer of zygote or early embryos with unto 8 blastomeres stage into the female accessory duct is called

Options

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

Answer

To solve the question regarding the assisted reproductive technology that involves the transfer of a zygote or early embryos with up to 8 blastomeres into the female accessory duct, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for a specific assisted reproductive technology (ART) that involves transferring a zygote or early embryo (up to 8 blastomeres) into the female accessory duct.

2. **Identifying Key Terms**:
- **Zygote**: A fertilized egg that is in the early stages of development.
- **Blastomeres**: Cells resulting from the division of a zygote.
- **Female Accessory Duct**: Refers to the fallopian tubes where the transfer occurs.

3. **Evaluating Options**:
- **GIFT (Gamete Intrafallopian Transfer)**: This technique involves transferring gametes (sperm and egg) into the fallopian tubes, not zygotes or embryos. Hence, it does not fit the criteria.
- **ZIFT (Zygote Intrafallopian Transfer)**: This is the correct term for transferring zygotes or early embryos (up to 8 blastomeres) into the fallopian tubes. This matches the description given in the question.
- **ICSI (Intracytoplasmic Sperm Injection)**: This technique involves injecting a single sperm directly into an egg and does not involve the transfer of zygotes or embryos.
- **IUT (Intrauterine Transfer)**: This involves transferring embryos (typically more than 8 blastomeres) into the uterus, which does not match the question's criteria.

4. **Conclusion**: Based on the evaluations, the correct answer is **GIFT**, which stands for **Zygote Intrafallopian Transfer**. This technique specifically involves the transfer of zygotes or early embryos into the female accessory duct (fallopian tubes).

### Final Answer:
The assisted reproductive technology that involves the transfer of zygote or early embryos with up to 8 blastomeres stage into the female accessory duct is called **ZIFT (Zygote Intrafallopian Transfer)**.
