What is false for ZIFT?

Options

A. ZIFT-Zygote Intra Fallopian Transfer
B. It follows IVF
C. Zygote or early embryo
D. Embryos with more than 8 blastomeres are transferred to the uterus

Answer

To determine what is false for ZIFT (Zygote Intra-Fallopian Transfer), we need to analyze the statements given about ZIFT and identify the incorrect one.

### Step-by-Step Solution:

1. **Understand ZIFT**: ZIFT stands for Zygote Intra-Fallopian Transfer. It is a type of Assisted Reproductive Technology (ART) used to treat infertility. In ZIFT, a zygote (fertilized egg) is transferred into the fallopian tube.

**Hint**: Remember that ZIFT involves the transfer of a zygote, not an embryo.

2. **Identify the Process**: In ZIFT, fertilization occurs in vitro (outside the body), and then the zygote is placed into the fallopian tube. This is different from other methods where embryos are transferred directly to the uterus.

**Hint**: Differentiate between zygote and embryo; ZIFT uses zygotes.

3. **Analyze the Statements**: Review each option provided regarding ZIFT to see which one is false.

- **Option 1**: ZIFT is a type of ART. (True)
- **Option 2**: ZIFT follows IVF (In Vitro Fertilization). (True)
- **Option 3**: ZIFT involves the transfer of zygotes or early embryos (up to 8 blastomeres). (True)
- **Option 4**: Embryos with more than 8 blastomeres are transferred to the uterus. (This statement is true but does not apply to ZIFT since ZIFT specifically involves zygotes.)

4. **Identify the False Statement**: The statement that is false for ZIFT is related to the transfer of embryos with more than 8 blastomeres, as ZIFT specifically involves the transfer of zygotes, not embryos.

**Final Answer**: The false statement for ZIFT is that embryos with more than 8 blastomeres are transferred to the uterus, as this does not pertain to the ZIFT process.

### Summary:
The false statement regarding ZIFT is that it involves the transfer of embryos with more than 8 blastomeres to the uterus, as ZIFT specifically deals with zygotes.
