In female genital tract, sperm capacitation is brought about by

Options

A. Hyaluronic acid
B. Removal of membrane fatty acids
C. Prostaglandins
D. Oxytocin

Answer

**Step-by-Step Solution:**

1. **Understanding Capacitation**: Capacitation is a physiological process that sperm undergo to gain the ability to fertilize an egg. It is crucial for successful fertilization.

2. **Location of Capacitation**: This process occurs in the female genital tract after the sperm have been deposited.

3. **Role of Chemicals**: Various substances in the female reproductive system contribute to sperm capacitation. These include:
- **Hyaluronic Acid**: This substance helps in the interaction between sperm and the surrounding environment.
- **Removal of Membrane Fatty Acids**: This process alters the sperm membrane, making it more fluid and conducive for fusion with the egg.
- **Prostaglandins**: These are lipid compounds that play a significant role in the capacitation process by promoting changes in the sperm that are necessary for fertilization.
- **Oxytocins**: These are hormones that may also influence sperm motility and function.

4. **Conclusion**: Among the mentioned substances, prostaglandins are particularly noted for their role in facilitating sperm capacitation in the female genital tract.

5. **Final Answer**: Therefore, sperm capacitation in the female genital tract is primarily brought about by **prostaglandins**.
