A female undergoing IVF treatment has blocked fallopian tubes. The technique by which the embryo with more than 8 blastomeres will be transferred into the female for further development is:
a) ZIFT
b) GIFT
c) IUT
d) Al

Options

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

Explanation

To solve the question regarding the technique used to transfer an embryo with more than 8 blastomeres into a female undergoing IVF treatment with blocked fallopian tubes, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Context**: The question states that the female has blocked fallopian tubes and is undergoing IVF treatment. We need to identify the correct technique for transferring an embryo with more than 8 blastomeres.

2. **Review the Options**:
- **ZIFT (Zygote Intra-Fallopian Transfer)**: This technique involves transferring a zygote (which has less than 8 blastomeres) into the fallopian tube. Since the fallopian tubes are blocked in this case, ZIFT cannot be used.
- **GIFT (Gamete Intra-Fallopian Transfer)**: This technique requires the fallopian tubes to be functional as it involves transferring both eggs and sperm into the fallopian tubes. Therefore, GIFT is also not applicable here.
- **IUT (Intra-Uterine Transfer)**: This technique involves transferring embryos (which can have more than 8 blastomeres) directly into the uterus. This method does not require the fallopian tubes to be open, making it suitable for this scenario.
- **AI (Artificial Insemination)**: This method involves injecting sperm into the female reproductive tract but does not involve the transfer of embryos, so it does not meet the criteria of transferring more than 8 blastomeres.

3. **Determine the Correct Answer**: Given that the only technique that allows for the transfer of embryos with more than 8 blastomeres directly into the uterus, without needing the fallopian tubes, is Intra-Uterine Transfer (IUT).

4. **Final Answer**: The correct technique is **IUT (Intra-Uterine Transfer)**.
