C. ZIFT involves IVF to help women who cannot produce ovum to bear a child
D. ZIFT involves IVF to help women who have damaged fallopian tubes to bear a child.

Answer

### Step-by-Step Solution:

1. **Understanding IUI (Intrauterine Insemination)**:
- IUI is a procedure where sperm is directly inserted into a woman's uterus.
- It is primarily used for women who have a normal ovarian reserve and can produce eggs.
- In cases of premature menopause, the woman does not produce eggs, making IUI ineffective for conception.

2. **Analyzing Option A**:
- Option A states that IUI can help a woman with premature menopause to bear a child.
- Since women in premature menopause do not produce eggs, IUI cannot facilitate conception.
- Therefore, **Option A is incorrect**.

3. **Understanding GIFT (Gamete Intra-Fallopian Transfer)**:
- GIFT involves transferring a female gamete (ovum) and male gamete (sperm) into the fallopian tubes.
- It is used for women who can produce eggs but may have issues with fertilization.

4. **Analyzing Option B**:
- Option B states that GIFT involves IVF to help women who cannot produce ovum to bear a child.
- This is incorrect because GIFT does not involve IVF; it directly transfers gametes into the fallopian tubes.
- Therefore, **Option B is incorrect**.

5. **Understanding ZIFT (Zygote Intra-Fallopian Transfer)**:
- ZIFT involves transferring a zygote (fertilized egg) into the fallopian tubes after IVF has taken place.
- It is suitable for women who cannot produce their own eggs but can still carry a pregnancy.

6. **Analyzing Option C**:
- Option C states that ZIFT involves IVF to help women who cannot produce ovum to bear a child.
- This is correct because ZIFT uses a zygote created through IVF, allowing women who cannot produce eggs to still conceive.
- Therefore, **Option C is correct**.

7. **Analyzing Option D**:
- Option D states that ZIFT involves IVF to help women who have damaged fallopian tubes to bear a child.
- This is incorrect because if the fallopian tubes are damaged, the zygote cannot travel to the uterus for implantation.
- Therefore, **Option D is incorrect**.

8. **Conclusion**:
- After analyzing all options, the only correct statement is **Option C**.
