Intra Uterine transfer is the transfer of embryo into the uterus of female at the stage of

Options

A. 32 - celled stage
B. > 8 celled blastomere stage
C. blastocyst
D. zygote

Answer

**Step-by-Step Solution:**

1. **Understanding Intrauterine Transfer**: Intrauterine transfer refers to the process of placing an embryo into the uterus of a female. This is a key step in assisted reproductive technology (ART).

2. **Identifying the Stage of the Embryo**: The question asks for the specific stage at which the embryo is transferred. It is important to know the developmental stages of an embryo.

3. **Stages of Embryo Development**:
- **Zygote Stage**: This is the very first stage after fertilization when the sperm and egg unite.
- **Cleavage Stage**: Following the zygote stage, the embryo undergoes several divisions, leading to the formation of a multicellular structure called a blastomere.
- **Blastocyst Stage**: This is a later stage where the embryo has developed into a hollow structure with an inner cell mass that will eventually form the fetus.

4. **Determining the Correct Stage for Transfer**: According to the information provided, intrauterine transfer occurs at the stage of more than 8 blastomeres, which is a part of the cleavage stage, leading up to the blastocyst stage.

5. **Conclusion**: Therefore, the correct answer to the question is that intrauterine transfer is performed at the stage of more than 8 cell blastomere stage.

**Final Answer**: Intrauterine transfer is the transfer of the embryo into the uterus of a female at the stage of more than 8 cell blastomere stage.
