B. A.I.
C. IUT
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding IVF**: In Vitro Fertilization (IVF) is a reproductive technique commonly referred to as the "test tube baby" program. It involves fertilizing an egg with sperm outside the body, in a controlled laboratory environment.

2. **Sperm and Egg Collection**: In the IVF process, sperm can be collected from either a male partner or a donor. Similarly, the ova (eggs) can be obtained from the female partner or a donor.

3. **Fertilization Process**: The collected sperm and eggs are then combined in the laboratory to facilitate fertilization, resulting in the formation of a zygote.

4. **Zygote Development**: The zygote undergoes cell division and develops into a structure called a blastocyst. The number of blastomeres (cells) in the zygote is crucial for the next steps. If the zygote has fewer than 8 blastomeres, it is typically implanted into the fallopian tube. If it has more than 8 blastomeres, it is implanted into the uterus.

5. **Transfer of Embryo**: The IVF technique includes the intrauterine transfer of the embryo (blastocyst) when it has developed sufficiently (more than 8 blastomeres). This is a critical step in the IVF process where the embryo is placed into the uterus to hopefully establish a pregnancy.

6. **Exclusion of Other Techniques**: It is important to note that IVF does not include techniques such as GIFT (Gamete Intrafallopian Transfer) or artificial insemination. GIFT involves the transfer of gametes to the fallopian tubes, while artificial insemination involves injecting sperm directly into the female reproductive tract.

7. **Conclusion**: Therefore, the IVF technique specifically includes intrauterine transfer of the embryo.

**Final Answer**: IVF technique includes intrauterine transfer.
