What is correct about the test-tube baby program ?

Options

A. The fertilisation of ovum with sperms occurs outside the female body , in the laboratory.
B. The resultant zygote upto 8 - blastomere stage is transferred to test tube for further development into baby.
C. In vitro fertilization is followed by embroyo transfer into fallopian tube or uterus of female.
D. Both (a) and (c)

Answer

To answer the question about what is correct regarding the test-tube baby program, we can break down the information provided in the video transcript into clear steps.

### Step-by-Step Solution:

1. **Understanding the Test-Tube Baby Program**:
- The test-tube baby program refers to the process of in vitro fertilization (IVF), where fertilization occurs outside the female body.

2. **Fertilization Process**:
- In this program, the female gamete (ovum) and male gamete (sperm) are combined in a laboratory setting. This is the first correct statement: "The fertilization of ovum with sperms occurs outside the female body in the laboratory."

3. **Development of the Zygote**:
- After fertilization, the resulting zygote begins to divide and develop. The transcript mentions that the zygote is transferred when it has more than 8 blastomeres, which is an important detail.

4. **Embryo Transfer**:
- The next step in the process is the transfer of the embryo. The zygote or early embryo is transferred into the fallopian tube or uterus of the female. This corresponds to the second correct statement: "In vitro fertilization is followed by embryo transfer into the fallopian tube or uterus of the female."

5. **Incorrect Statement**:
- The statement that the resultant zygote up to the 8 blastomere stage is transferred to a test tube for further development is incorrect. Instead, it is the zygote with more than 8 blastomeres that is transferred to the female's fallopian tube.

6. **Final Conclusion**:
- Based on the above points, the correct options regarding the test-tube baby program are both A and C:
- A: Fertilization occurs outside the female body in the laboratory.
- C: In vitro fertilization is followed by embryo transfer into the fallopian tube or uterus of the female.
