Which contraceptive methods have the highest failure rates?

Clinically, there is no specific statement on which contraceptive methods have the highest failure rates. Generally, contraceptive methods such as withdrawal, condom use, medication, and intrauterine device placement all have certain failure rates.

Withdrawal is a common contraceptive method to prevent sperm from entering the vagina. However, during sexual activity, some sperm may still enter the vagina, resulting in accidental pregnancy.

Using a condom is a common contraceptive device. However, improper use can lead to tears or slippage during sexual activity, which may result in contraceptive failure.

Medication, such as oral contraceptives or injectable contraceptives, usually has a low failure rate when used correctly. However, forgetting to take the medication or using it at the incorrect time can increase the risk of contraceptive failure.

Intrauterine device placement is a common contraceptive measure. However, improper operation can lead to displacement or expulsion of the device, as well as a series of adverse reactions, which may affect the contraceptive effect.

Regardless of the contraceptive method chosen, it is recommended to consult with a doctor to increase the chances of successful contraception.
