Use of spermicidal creams, jellies and foams along with diaphrams, cervical and vaults leads to

Options

A. Increased contraceptive efficiency
B. Prevention of ovulation
C. Prevention of implantation
D. Increased sexual desire and drive.

Answer

**Step-by-Step Solution:**

1. **Understanding the Methods of Contraception**: The question involves two types of contraceptive methods: chemical methods (spermicidal creams, jellies, and foams) and barrier methods (diaphragms, cervical caps, and vaults).

2. **Chemical Methods**: Spermicidal creams, jellies, and foams contain chemicals that kill sperm. This method is effective in preventing sperm from fertilizing an egg.

3. **Barrier Methods**: Diaphragms, cervical caps, and vaults are physical barriers that cover the cervix, preventing sperm from entering the uterus. This method also helps in preventing fertilization.

4. **Combining Methods**: When spermicidal agents are used in conjunction with barrier methods, the effectiveness of contraception is significantly increased. The sperm is not only blocked by the barrier but also killed by the spermicide.

5. **Conclusion**: Therefore, the combined use of spermicidal creams, jellies, and foams with diaphragms, cervical caps, and vaults leads to a higher contraceptive efficiency, effectively preventing pregnancy.

6. **Eliminating Other Options**:
- **Prevention of Ovulation**: This is not achieved through the mentioned methods; it typically requires hormonal contraceptives.
- **Prevention of Implantation**: This is also not applicable as it involves different contraceptive methods.
- **Increase in Sexual Desire**: The mentioned methods do not affect sexual desire or drive.

7. **Final Answer**: The correct answer is that the combined use of these methods leads to increased contraceptive efficiency.
