The failure rate of Condom with typical use is:
**Core Concept**
The failure rate of a contraceptive method refers to the percentage of users who experience unintended pregnancy over a specified period. Condoms, when used correctly and consistently, provide effective protection against sexually transmitted infections (STIs) and unintended pregnancy. However, the typical use failure rate accounts for real-world usage, which may not always adhere to ideal usage guidelines.
**Why the Correct Answer is Right**
The failure rate of condoms with typical use is influenced by factors such as incorrect or inconsistent use, breakage, or slippage. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) estimate that the typical use failure rate for male condoms is approximately 18%. This rate reflects the actual effectiveness of condoms in real-world settings, where users may experience difficulties with proper application, removal, or may forget to use them.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it is lower than the estimated typical use failure rate for male condoms.
**Option B:** This option is incorrect as it is higher than the estimated typical use failure rate for male condoms.
**Option C:** This option is incorrect as it is not a recognized estimate for the typical use failure rate of male condoms.
**Clinical Pearl / High-Yield Fact**
It's essential to note that the failure rate of condoms can be significantly influenced by user behavior, making education on proper use and consistent application crucial for effective contraception.
**Correct Answer: B. 21%**
