In which of the following technique can be used when female can provide suitable environment for fertilization but cannot produce an ovum?

Options

A. ICSI
B. ZIFT
C. GIFT
D. Al

Answer

To answer the question regarding the technique that can be used when a female can provide a suitable environment for fertilization but cannot produce an ovum, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**: The question states that the female can provide a suitable environment for fertilization but is unable to produce an ovum. This indicates a need for a reproductive technology that compensates for the lack of ovum production.

2. **Identifying the Techniques**: We need to evaluate the available reproductive techniques:
- **ICSI (Intracytoplasmic Sperm Injection)**: This technique is primarily used for male infertility, where a single sperm is injected directly into an ovum. It does not address female infertility related to ovum production.
- **ZIFT (Zygote Intra Fallopian Transfer)**: In this method, a zygote (fertilized ovum) is placed into the fallopian tube. This requires the presence of an ovum, which the female in question cannot produce.
- **GIFT (Gamete Intra Fallopian Transfer)**: This technique involves transferring gametes (sperm and ovum) into the fallopian tube. Again, this requires the female to produce an ovum, which is not the case here.
- **Artificial Insemination (AI)**: This method involves injecting sperm directly into the female's reproductive tract. It does not require the female to produce an ovum, but it does not facilitate fertilization without an ovum.

3. **Determining the Correct Technique**: Given the options and their definitions, none of the techniques mentioned directly solve the problem of a female who cannot produce an ovum but can provide a suitable environment. However, the closest method that allows for the use of a female's reproductive environment without her producing an ovum would be to use donor eggs or embryos in conjunction with methods like IVF (In Vitro Fertilization), which is not explicitly listed in the options.

4. **Conclusion**: Since the question does not provide an option for IVF or embryo transfer directly, the best answer based on the provided techniques is **GIFT**, as it allows for the transfer of gametes, assuming donor eggs are used.

### Final Answer:
**GIFT (Gamete Intra Fallopian Transfer)** is the technique that can be used when a female can provide a suitable environment for fertilization but cannot produce an ovum.
