The correct Answer is:
### Step-by-Step Solution: 1. **Understanding IUDs**: - IUDs (Intrauterine Devices) are contraceptive devices inserted into the female uterus to prevent pregnancy. 2. **Analyzing Statement I**: - **Statement I**: "Increase phagocytosis of sperms." - **Explanation**: IUDs can enhance the immune response in the female reproductive tract, leading to increased phagocytosis of sperm by immune cells. - **Conclusion**: This statement is **True**. 3. **Analyzing Statement II**: - **Statement II**: "Release Cu ions that suppress sperm motility and fertilising capacity of sperms." - **Explanation**: Some IUDs, specifically copper IUDs, release copper ions which are known to decrease sperm motility and their ability to fertilize an egg. - **Conclusion**: This statement is **True**. 4. **Analyzing Statement III**: - **Statement III**: "Make the uterus unsuitable for implantation." - **Explanation**: IUDs create an environment in the uterus that is not conducive to implantation, thus preventing pregnancy. - **Conclusion**: This statement is **True**. 5. **Analyzing Statement IV**: - **Statement IV**: "Make the cervix hostile to sperms." - **Explanation**: IUDs can thicken cervical mucus, making it more difficult for sperm to enter the uterus, thus creating a hostile environment for sperm. - **Conclusion**: This statement is **True**. 6. **Analyzing Statement V**: - **Statement V**: "Prevent semen from entering the female reproductive tract." - **Explanation**: IUDs do not physically block semen from entering the reproductive tract; rather, they work by other mechanisms to prevent fertilization and implantation. - **Conclusion**: This statement is **False**. ### Final Summary: - Statements I, II, III, and IV are **True**. - Statement V is **False**.
