Should individuals with polycystic ovary syndrome (PCOS) take birth control pills?


Hello, I have polycystic ovary syndrome (PCOS).
Besides having very irregular menstrual cycles, I don't have any other obvious symptoms, but I have confirmed it through blood tests and ultrasounds.
My menstrual cycle is very irregular; the last time I had my period was five months ago, and the flow was light.
I currently do not want to get pregnant, but I would like to prepare for pregnancy in the next 3-5 years.
Should I take birth control pills to regulate my menstrual cycle, aiming for it to occur every three months (or I wouldn't mind having it monthly)? However, I am concerned that taking the pills now might affect my chances of getting pregnant in the future.
I'm also worried that starting the pills might make it easier to conceive later or that stopping them might lead to increased fertility.
I usually exercise five days a week (strength training and cardio) and eat healthily.
Although I love sweets, my weight is not heavy, and my body fat percentage is within or below the normal range.
Given my current situation, what would be the best course of action? Thank you.

Hello Ms.
Tina: Currently, there is no specific medication for the management of polycystic ovary syndrome (PCOS).
If your menstrual cycle occurs only once every few months, taking birth control pills is certainly an option, especially since you mentioned that you do not wish to become pregnant at this time; it is a better choice.
If taking birth control pills does not lead to weight gain or severe side effects such as nausea or vomiting, then it can be used.
Birth control pills will not affect your chances of becoming pregnant in the future, so there is no need to worry.
If you prefer not to take birth control pills, you may also consider using cyclical progesterone to regulate your menstrual cycle.

More Info


Women with Polycystic Ovary Syndrome (PCOS) often experience irregular menstrual cycles due to hormonal imbalances. This condition can lead to various symptoms, including weight gain, acne, and excessive hair growth, but not all women with PCOS exhibit these symptoms. Given your situation, where you have irregular periods and are not currently trying to conceive but plan to in the next few years, considering birth control pills can be a viable option.

Benefits of Birth Control Pills for PCOS:
1. Regulation of Menstrual Cycles: Birth control pills can help regulate your menstrual cycle, making it more predictable. This is particularly beneficial for women with PCOS who experience long intervals between periods. By taking the pill, you can induce a monthly withdrawal bleed, which can help manage the risk of endometrial hyperplasia (thickening of the uterine lining) that can occur with prolonged periods of amenorrhea (absence of menstruation).

2. Hormonal Balance: Birth control pills contain estrogen and progestin, which can help balance hormone levels in women with PCOS. This can reduce the levels of androgens (male hormones) that are often elevated in PCOS, potentially alleviating symptoms like acne and excessive hair growth.

3. Improved Ovulation: While you are not currently trying to conceive, regulating your cycle with birth control can help prepare your body for future pregnancies. Some studies suggest that using birth control pills may help restore normal ovulation patterns once you stop taking them, although individual responses can vary.

4. Reduced Risk of Complications: Regular menstruation can help reduce the risk of complications associated with PCOS, such as endometrial cancer, which is a concern for women who do not have regular periods.

Considerations Before Starting Birth Control Pills:
- Future Fertility: There is a common concern that taking birth control pills may affect future fertility. However, research indicates that most women with PCOS can conceive after discontinuing the pill. The key is to ensure that you are managing your PCOS effectively, which includes maintaining a healthy lifestyle, managing weight, and monitoring your menstrual health.

- Monitoring Symptoms: If you decide to start birth control pills, it is essential to monitor how your body responds. Some women may experience side effects, and it’s important to communicate with your healthcare provider about any concerns.

- Lifestyle Factors: Since you are already engaging in regular exercise and maintaining a healthy diet, continue these practices. Weight management can significantly impact the symptoms of PCOS and improve insulin sensitivity, which is often impaired in women with this condition.

- Consultation with a Healthcare Provider: Before starting any medication, including birth control pills, it’s crucial to consult with your healthcare provider. They can help you weigh the benefits and risks based on your individual health profile and future pregnancy plans.

In conclusion, taking birth control pills can be a beneficial strategy for managing irregular periods associated with PCOS, especially if you are not currently trying to conceive. They can help regulate your cycle, balance hormones, and prepare your body for future pregnancies. However, it is essential to have an open dialogue with your healthcare provider to ensure that this approach aligns with your long-term reproductive goals and overall health.

Hello, taking contraceptive pills suppresses ovulation, so there is no need to measure basal body temperature. If you want to get pregnant, switch to ovulation-inducing medication. Contraceptive pills inhibit ovulation rather than causing the eggs to die. Wishing you good health.
