D. IUI

Answer

To solve the question "In which of the following ART techniques is the semen artificially introduced into the female?", we need to analyze each of the provided options one by one.

### Step-by-Step Solution:

1. **Understanding the Options:**
- The options given are:
- A) ET (Embryo Transfer)
- B) GIFT (Gamete Intrafallopian Transfer)
- C) IUT (Intrauterine Transfer)
- D) IUI (Intrauterine Insemination)

2. **Analyzing ET (Embryo Transfer):**
- ET involves fertilization of male and female gametes outside the body (in vitro) and then transferring the embryo into the uterus.
- **Conclusion:** This technique does not involve the direct introduction of semen into the female. Thus, it is not the correct answer.

3. **Analyzing GIFT (Gamete Intrafallopian Transfer):**
- GIFT is used in cases where a female cannot produce ova but can support fertilization and embryo development. In this method, gametes are transferred into the fallopian tubes.
- **Conclusion:** This technique does not involve the introduction of semen directly into the female. Thus, it is not the correct answer.

4. **Analyzing IUT (Intrauterine Transfer):**
- IUT refers to the transfer of embryos (after IVF) into the uterus. It is a subsequent step after fertilization has occurred.
- **Conclusion:** This technique does not involve the introduction of semen into the female. Thus, it is not the correct answer.

5. **Analyzing IUI (Intrauterine Insemination):**
- IUI is specifically designed for cases where the husband has low sperm count or is unable to inseminate. In this method, the semen is artificially introduced into the female's uterus or vagina.
- **Conclusion:** This technique directly involves the introduction of semen into the female, making it the correct answer.

### Final Answer:
The correct answer is **D) IUI (Intrauterine Insemination)**.
