Hyaluronidase is present in

Options

A. Ovary
B. Ovum
C. Sperm
D. Blood.

Answer

**Step-by-Step Solution:**

1. **Understanding Hyaluronidase**: Hyaluronidase is an enzyme that breaks down hyaluronic acid, which is a component of the extracellular matrix. This enzyme is crucial for various biological processes, including tissue remodeling and penetration through biological barriers.

2. **Identifying the Function of Hyaluronidase in Reproduction**: In the context of human reproduction, hyaluronidase plays a significant role in the fertilization process. It helps sperm penetrate the protective layers surrounding the ovum (egg), specifically the granulosa cells and the zona pellucida.

3. **Locating the Source of Hyaluronidase**: The enzyme hyaluronidase is produced and found on the surface of sperm cells. This positioning allows the sperm to effectively break down the hyaluronic acid in the extracellular matrix surrounding the ovum, facilitating the sperm's ability to reach and fertilize the egg.

4. **Choosing the Correct Answer**: Given the options provided (ovary, ovum, sperm, or blood), the correct answer is sperm, as this is where hyaluronidase is primarily located and functions during the fertilization process.

5. **Final Answer**: Therefore, the correct option is **sperm**.
