All the following statement about ZIFT are correct, but one is wrong. Which one is wrong ?

Options

A. It is zygote intra-fallopian transfer (ZIFT).
B. Zygote is transferred into the fallopian tube after IVF.
C. Early embryos up to 8 blastomers can also be transferred into the fallopian tubes.
D. Embryos with more than 8 blastomeres are also transferred into the fallopian tubes.

Answer

To determine which statement about ZIFT (Zygote Intrafallopian Transfer) is incorrect, let's analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding ZIFT**: ZIFT stands for Zygote Intrafallopian Transfer, which is a technique used in assisted reproductive technology (ART). In this procedure, fertilization occurs in vitro (in a laboratory), and the resulting zygote is transferred into the fallopian tube.

2. **Analyzing the Statements**:
- **Statement 1**: "It is a zygote in the fallopian transfer."
- This statement is correct. ZIFT involves transferring a zygote into the fallopian tube.

- **Statement 2**: "Zygote is transferred into the fallopian tube after IVF."
- This statement is also correct. The zygote is indeed transferred to the fallopian tube after fertilization (IVF).

- **Statement 3**: "Early embryos up to 8 blastomeres can also be transferred into the fallopian tube."
- This statement is correct as well. ZIFT allows for the transfer of zygotes or embryos with up to 8 blastomeres.

- **Statement 4**: "Embryos with more than 8 blastomeres are also transferred into the fallopian tubes."
- This statement is incorrect. In ZIFT, typically only zygotes or embryos with up to 8 blastomeres are transferred; embryos with more than 8 blastomeres are usually transferred to the uterus in a different procedure known as IVF.

3. **Conclusion**: The incorrect statement is **Statement 4**: "Embryos with more than 8 blastomeres are also transferred into the fallopian tubes."

### Final Answer:
The wrong statement about ZIFT is: **"Embryos with more than 8 blastomeres are also transferred into the fallopian tubes."**
