Effectiveness

The failure rate of condoms in couples who use them consistently and correctly during the first year of use is estimated to be about 3%. However, the true failure rate is estimated to be about 14% during the first year of typical use. This marked difference of failure rates reflects errors in how they are used.

• Some couples fail to use condoms every time they have sexual intercourse.
  
  
• Condoms may fail (break or come off) if you use the wrong type of lubricant. (For example, using an oil-based lubricant with a latex condom will cause it to fall apart.)
  
  
• The condom may not be placed properly on the penis. Also, the man may not use care when withdrawing.
