Embryo with more than 16 blastomeres formed due to in vitro ferilization is transferred into

Options

A. Uterus
B. Fallopian tube
C. Fimbriae
D. Cervix

Answer

**Step-by-Step Solution:**

1. **Understanding Blastomeres**:
- After fertilization, the zygote undergoes rapid mitotic divisions, leading to the formation of cells called blastomeres.
- Initially, the zygote divides to form two cells, then four, and so on, until it reaches an 8-cell stage and subsequently a 16-cell stage, known as the morula.

2. **Identifying the Process of In Vitro Fertilization (IVF)**:
- In vitro fertilization is a procedure where fertilization occurs outside the body.
- The sperm and egg are combined in a laboratory setting, and once fertilization occurs, the resulting embryo begins to divide.

3. **Determining the Stage of the Embryo**:
- The question specifies an embryo with more than 16 blastomeres, which indicates that it has developed beyond the morula stage.

4. **Understanding Where to Transfer the Embryo**:
- The embryo, once it has more than 16 blastomeres, is typically transferred to the uterus.
- The uterus is the ideal location for implantation, where the embryo can embed itself into the uterine lining and continue its development.

5. **Conclusion**:
- Therefore, the correct answer to the question is that an embryo with more than 16 blastomeres formed due to in vitro fertilization is transferred into the uterus.

**Final Answer**: Uterus
