What is the effectiveness rate of a diaphragm as a contraceptive method?

• A. 78-82%
• B. 88-94%
• C. 95-100%
• D. 60-70%

Answer: (B)

The effectiveness rate of a diaphragm as a contraceptive method is often reported to be between 88-94% when used correctly and consistently. This range reflects the percentage of women who prevent pregnancy over the course of a year of typical use.

A diaphragm is a barrier method of contraception that needs to be inserted into the vagina before intercourse and used with spermicide to increase its effectiveness. This means that proper use is crucial; users must be diligent in ensuring it is in place every time sexual activity occurs.

Options that suggest lower effectiveness rates, such as those that indicate a range of 78-82% or 60-70%, do not account for the higher success rate achievable through proper use and correct insertion of the device. Similarly, the highest effectiveness range of 95-100% may imply a level of reliability associated more with surgical methods or hormonal contraceptives, rather than barrier methods like the diaphragm. Thus, the range of 88-94% accurately reflects the potential effectiveness of the diaphragm within real-world usage contexts.
