What leads to Contraception Failure

In USA, 53 percent of unplanned pregnancies occur in women who have been using contraceptives. There are many factors which lead to unplanned pregnancy due to contraception failure.

Causes of Contraception Failure


  • Instructions of use not followed – Every method of contraception requires the user to follow some directions failing which, the success in preventing pregnancy cannot be ensured. For example, when used correctly condoms prevent pregnancy 98 percent of the times but the success rate drops to 85 percent when condoms are not used as instructed. Similarly, when taking contraceptive pills, the direction of taking the pills daily at one time need to be followed for better chances of contraception. If not followed, the chances of conception increase. Same holds true for other contraceptives such as IUD, cervical cap or diaphragm.

  • Inconsistency in using contraceptives – If you become carefree about using your contraceptives regularly, the chances of getting pregnant rise considerably. Not taking the contraceptive pill even once would significantly increase the chances of conceiving and you might have to resort to an emergency contraceptive for making sure. Similarly, barrier methods such as condoms, cervical caps and diaphragms must be used every time you have sex, not forgetting or avoiding even once. You should try to perfect natural family planning if you do not find favour with contraceptives.
  • Drugs that render your contraceptive ineffective – If you are on certain medications which contain drugs that can interact with or interrupt the oral contraceptive used by you; its effectiveness may be hampered. Take the advice of your doctor or pharmacist to know if such can be the case.

  • Misconceptions about fertility period – Many women think that not being in their fertility period is going to save them from getting pregnant. Research and experience has shown that conception can occur at any time of the month and no period is completely safe. Moreover, if you are on oral contraceptives, menstruation does not occur. Barrier methods may be needed even during menstrual period.
  • Age factor – One-fourth of the unplanned pregnancy occurs in women below the age of 20. That makes lack of experience or immaturity of adolescents an important factor of contraception failure.
