Test tube baby technique involves artificial insemination.

Answer

**Step-by-Step Solution:**

1. **Understanding Test Tube Baby Technique**: The term "test tube baby" refers to the process of in vitro fertilization (IVF), where fertilization occurs outside the body, specifically in a laboratory setting.

2. **Process of In Vitro Fertilization**: In this technique, sperm is collected from the male and an egg (ovum) is collected from the female. These are then combined in a controlled environment (the "test tube") to allow fertilization to occur, forming a zygote.

3. **Development of the Zygote**: Once the zygote is formed, it is then implanted into the female's uterus, where it can develop into a fetus and eventually a baby.

4. **Understanding Artificial Insemination**: Artificial insemination is a different technique. It involves directly injecting sperm into the female's reproductive tract (usually the vagina) to increase the chances of fertilization, especially when the male has low sperm count.

5. **Comparison of Techniques**: The key difference is that in IVF (test tube baby technique), fertilization occurs outside the body, while in artificial insemination, fertilization occurs inside the female's body.

6. **Conclusion**: Since the statement claims that the test tube baby technique involves artificial insemination, and given that these are two distinct processes, the statement is false.

**Final Answer**: The statement "Test tube baby technique involves artificial insemination" is **false**.
