In which of the following assisted reproductive techniques the cryopreserved semen is utilized to achieve Fertilization ?

Options

A. Intrauterine insemination
B. Gamete in fertilization technology
C. Gameta intra fallopian transfer
D. Intrauterine contraceptive technique

Answer

To solve the question regarding which assisted reproductive technique utilizes cryopreserved semen to achieve fertilization, we can follow these steps:

### Step 1: Understand the Question
The question asks for an assisted reproductive technique that specifically uses cryopreserved semen for fertilization.

### Step 2: Define Key Terms
- **Cryopreserved Semen:** This refers to sperm that has been preserved at very low temperatures to maintain its viability for future use.
- **Assisted Reproductive Techniques (ART):** These are medical procedures used primarily to address infertility.

### Step 3: Analyze the Options
Let’s evaluate each option provided:
- **a. Intrauterine insemination (IUI):** This technique involves placing sperm directly into the uterus during ovulation. It can use fresh or cryopreserved sperm.
- **b. Gamete fertilization technology:** This is a broad term and does not specifically refer to a technique that uses cryopreserved semen.
- **c. Gamete intrafallopian transfer (GIFT):** This involves placing both eggs and sperm directly into the fallopian tubes. It typically uses fresh gametes.
- **d. Intrauterine contraceptive techniques:** This refers to methods used to prevent pregnancy and does not involve fertilization.

### Step 4: Identify the Correct Answer
From the analysis, the only technique that specifically uses cryopreserved semen for the purpose of achieving fertilization is:
- **a. Intrauterine insemination (IUI)**

### Conclusion
The correct answer is **a. Intrauterine insemination (IUI)**.
