In IUET, embryo with more than 8 blastomeres are transffered in

Answer

**Step-by-Step Solution:**

1. **Understanding IUET**: IUET stands for Intrauterine Embryo Transfer. It is a reproductive technology used primarily for women who are infertile and cannot produce their own ova (eggs).

2. **Process of IUET**: In this process, sperm is collected from the male partner or a donor, and ova are collected from a female donor. These sperm and ova are then fertilized in a laboratory setting, often referred to as a test tube, which is why the resulting baby is commonly known as a "test tube baby."

3. **Fertilization and Early Development**: Normally, fertilization occurs in the fallopian tubes of the female. However, in the case of IUET, fertilization is induced in a controlled environment (the test tube) that mimics the conditions of the female reproductive system.

4. **Blastomere Formation**: After fertilization, the zygote (fertilized egg) begins to divide. The first few divisions lead to the formation of blastomeres. An embryo with 8 blastomeres is at a specific developmental stage.

5. **Transfer of Embryos**:
- If the embryo has **8 blastomeres**, it is transferred to the fallopian tube using a technique called Zygote Intra-Fallopian Transfer (ZIFT).
- If the embryo has **more than 8 blastomeres**, it is transferred into the uterus. This procedure is referred to as Intrauterine Embryo Transfer (IUET).

6. **Conclusion**: Therefore, in IUET, embryos with more than 8 blastomeres are transferred into the uterus.

**Final Answer**: In IUET, embryos with more than 8 blastomeres are transferred into the uterus.
