Question

Uses of spermicidal creams, jellies and foams along with barriers

BALASOURY · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
**Primary Concept**: Contraception
**Related Topics**: Spermicides, Barrier Methods, Reproductive Health
**Prerequisites**: Basic understanding of human reproduction and contraception methods.
## SOLUTION PATHWAY
**Given Information**:
    The question asks about the function of spermicidal creams, jellies, and foams when used with barrier methods.
**Method & Steps**:
1. Identify the primary function of spermicides: To kill or immobilize sperm.
    Reasoning: Spermicides are designed to prevent sperm from reaching the egg.
2. Connect spermicide use with barrier methods: Barrier methods physically block sperm, and spermicides enhance this effect.
    Reasoning: Combined, they provide a dual approach to contraception.
3. Determine the impact on contraceptive efficiency: They increase effectiveness by adding a chemical barrier to the physical one.
    Result: This combination increases contraceptive efficiency.
 ## OPTION ANALYSIS
[A] :x: Spermicides do not prevent menstruation.
[B] :x: Spermicides do not primarily prevent STDs, although they may offer minimal protection. Barrier methods like condoms are more effective for STD prevention.
[C] ✓: Spermicides, when used with barriers, increase the effectiveness of contraception.
[D] :x: Spermicides inhibit sperm motility, not provide it.
 ## LEARNING AIDS
**Common Mistakes**:
1. Confusing spermicides with STD prevention: Spermicides are primarily for contraception, not protection against STDs.
2.  Misunderstanding the mechanism of action: Spermicides kill or immobilize sperm, not aid their movement.
**Quick Tips**:
1. Remember 'spermi-cide' as 'sperm-killing' to recall its purpose.
2. Visualize the combined action of a physical barrier and a chemical barrier for enhanced contraception.
