A patient desires a reversible contraceptive method that also reduces her risk of ovarian cancer. Which of the following is the most appropriate choice?

The correct answer is C.

• A. Bilateral tubal ligation is a permanent sterilization method. The patient desires pregnancy in the future, so this option is not appropriate.
• B. Levonorgestrel intrauterine device is a highly effective contraceptive, but its primary benefit is not ovarian cancer risk reduction. While some studies suggest a possible reduction, it is not as pronounced or well-established for this specific purpose as combined oral contraceptives.
• C. Combined oral contraceptives (COCs) are known to significantly reduce the risk of ovarian cancer. This protective effect increases with the duration of use and persists after discontinuation. COCs are also reversible, allowing the patient to conceive in the future when desired. This option best meets both the patient's desire to decrease ovarian cancer risk and her wish for future pregnancy.

The most appropriate contraceptive management is C. Combined oral contraceptives.
