The correct Answer is:
To solve the question regarding how diaphragms, cervical caps, and vaults prevent conception, we can analyze each option step by step. ### Step-by-Step Solution: 1. **Understanding the Mechanism of Action**: - Diaphragms, cervical caps, and vaults are considered barrier methods of contraception. They are designed to physically block sperm from entering the uterus. 2. **Analyzing Each Option**: - **Option A: Increasing phagocytosis of sperm within the uterus**: - This option suggests that these devices enhance the immune response to sperm. However, this is not their primary function. Barrier methods do not increase phagocytosis of sperm. - **Option B: Suppressing sperm motility**: - This option implies that these devices hinder the movement of sperm. While some contraceptives do affect sperm motility (like certain IUDs), barrier methods primarily block sperm rather than directly affecting their motility. - **Option C: Inhibiting ovulation and implantation**: - This option refers to mechanisms that prevent ovulation or the implantation of a fertilized egg. This is typically the function of hormonal contraceptives (like the pill), not barrier methods. - **Option D: Blocking the entry of sperm through the cervix**: - This option accurately describes the primary function of diaphragms, cervical caps, and vaults. By covering the cervix, these devices physically prevent sperm from entering the uterus. 3. **Conclusion**: - After analyzing all the options, it is clear that the correct answer is **(d) blocking the entry of sperm through the cervix**. This is the primary mechanism by which diaphragms, cervical caps, and vaults prevent conception. ### Final Answer: The correct option is **(d) blocking the entry of sperm through the cervix**.
