Which of the following artificial techniques uses cryogenically preserved sperm?

Options

A. Artificial insemination
B. GIFT
C. Vasectomy
D. Superovulation

Answer

To answer the question "Which of the following artificial techniques uses cryogenically preserved sperm?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which artificial technique utilizes cryogenically preserved sperm. Cryogenic preservation involves cooling biological samples to very low temperatures to preserve them for future use.

2. **Analyze the Options**:
- **Option A: Artificial Insemination**: This technique involves the artificial introduction of sperm into the female reproductive system. It can use sperm that has been cryogenically preserved, making this a strong candidate.

- **Option B: GIFT (Gamete Intrafallopian Transfer)**: This technique involves transferring both male and female gametes directly into the fallopian tubes. It does not specifically require cryogenically preserved sperm, so this option is likely incorrect.

- **Option C: Vasectomy**: This is a surgical procedure for male sterilization where the vas deferens is cut and sealed. It does not involve the use of sperm, let alone cryogenically preserved sperm, making this option incorrect.

- **Option D: Super Ovulation**: This refers to a process where hormones are used to induce the production of multiple eggs in a female. This technique does not involve sperm, and therefore does not utilize cryogenically preserved sperm.

3. **Conclusion**: After analyzing all the options, the correct answer is **Option A: Artificial Insemination**. This technique is the only one that uses cryogenically preserved sperm.

### Final Answer:
**Artificial Insemination**
