Options

A. ZIFT
B. ICSI
C. GIFT
D. All of the above

Answer

To solve the question regarding which assisted reproductive technique is applicable for a woman who cannot ovulate regularly but can provide a suitable environment for fertilization, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for an assisted reproductive technique suitable for a woman who cannot ovulate regularly but can still support fertilization.

2. **Identify the Techniques**: The options given are:
- A. ZIFT (Zygote Intra-Fallopian Transfer)
- B. ICSI (Intracytoplasmic Sperm Injection)
- C. GIFT (Gamete Intra-Fallopian Transfer)
- D. All of the above

3. **Analyze Each Technique**:
- **ZIFT**: This technique involves fertilizing the egg outside the body and then transferring the zygote into the fallopian tube. It requires the woman to produce eggs.
- **ICSI**: This method is used primarily in cases of male infertility where a single sperm is injected directly into an egg. It does not directly address the issue of ovulation in women.
- **GIFT**: This technique involves taking an egg from a donor and placing it directly into the fallopian tube of a woman who cannot produce her own eggs but can provide a suitable environment for fertilization.

4. **Determine the Most Suitable Option**: Since the question specifies a woman who cannot ovulate but can support fertilization, GIFT is the most appropriate technique. It allows for the introduction of a donor egg into the fallopian tube of a woman who has the capacity for fertilization and embryo development.

5. **Conclusion**: Therefore, the answer to the question is **C. GIFT**.
