From the Guidelines
Managing PCOS for fertility involves a multi-faceted approach combining lifestyle changes, medications, and possibly assisted reproductive technologies, with the most recent evidence suggesting that bariatric surgery may be a potential adjunct therapy for patients with excess weight. The first step in managing PCOS for fertility is to adopt a healthy lifestyle, including a low-glycemic diet and regular exercise, as this can improve ovulation and pregnancy rates, even with a 5-10% weight reduction 1.
Lifestyle Changes
- Weight loss, if overweight, to improve ovulation and pregnancy rates
- Adopt a low-glycemic diet to improve insulin sensitivity
- Exercise regularly, at least 150 minutes weekly, to improve overall health and fertility
- Manage stress through techniques like yoga or meditation to improve overall well-being
Medications
- Metformin (500-2000mg daily) to improve insulin sensitivity and restore ovulation
- Letrozole (2.5-7.5mg for 5 days) is now preferred over clomiphene citrate for ovulation induction in PCOS patients due to higher live birth rates, although the provided evidence does not specifically mention letrozole, the most recent and highest quality study on the topic should be consulted for the most up-to-date recommendations.
Assisted Reproductive Technologies
- Gonadotropin therapy or laparoscopic ovarian drilling may be recommended if other approaches do not work
- In vitro fertilization (IVF) offers good success rates, though women with PCOS need careful monitoring to prevent ovarian hyperstimulation syndrome
Additional Considerations
- Regular prenatal vitamins with folic acid (400mcg daily) are essential before conception
- Bariatric surgery may be a potential adjunct therapy for patients with excess weight, as it has been shown to improve anthropometric, reproductive, hormonal, and metabolic outcomes in women with PCOS 1.
It is essential to note that while the provided evidence does not specifically mention letrozole, the most recent and highest quality study on the topic should be consulted for the most up-to-date recommendations. Additionally, the evidence suggests that lifestyle changes, including diet and exercise, are crucial in managing PCOS and improving fertility outcomes 1.
From the FDA Drug Label
Clomiphene citrate is indicated for the treatment of ovulatory dysfunction in women desiring pregnancy. Impediments to achieving pregnancy must be excluded or adequately treated before beginning clomiphene citrate therapy Those patients most likely to achieve success with clomiphene therapy include patients with polycystic ovary syndrome Properly timed coitus in relationship to ovulation is important A basal body temperature graph or other appropriate tests may help the patient and her physician determine if ovulation occurred.
To manage PCOS and fertility,
- Clomiphene citrate can be used to treat ovulatory dysfunction in women desiring pregnancy.
- Impediments to pregnancy must be excluded or adequately treated before beginning therapy.
- Properly timed coitus in relationship to ovulation is important.
- A basal body temperature graph or other appropriate tests may help determine if ovulation occurred. 2
From the Research
Managing PCOS and Fertility
To manage PCOS and fertility, several strategies can be employed, including:
- Weight management, as obesity can exacerbate PCOS symptoms and reduce fertility treatment efficacy 3
- Lifestyle interventions, such as diet and exercise, as first-line treatment for weight loss, although the impact on fertility is limited 3
- Pharmacotherapy, including metformin, clomiphene citrate, and letrozole, which can result in significant weight loss and improved conception rates 3, 4, 5
- Bariatric surgery, which can lead to significant weight loss, although the evidence for its impact on fertility is limited 3
Medications for Inducing Ovulation
For inducing ovulation in women with PCOS, several medications can be used, including:
- Clomiphene citrate, which is often used as first-line treatment, but may have limited efficacy in some women 4, 5
- Letrozole, which has been shown to be more effective than clomiphene citrate in inducing ovulation and achieving pregnancy in some studies 4, 5
- Metformin, which can be used in combination with clomiphene citrate or letrozole to improve ovulation and pregnancy rates 5, 6
Dietary and Lifestyle Modifications
Dietary and lifestyle modifications can also play a crucial role in managing PCOS and fertility, including:
- A balanced diet with 40% energy from carbohydrates, 30% from fats, and 30% from protein, which can help reduce PCOS symptoms and improve metabolic balance 7
- Optimum physical activity, which can help reduce PCOS symptoms and improve fertility 7
- Herbal extracts, which may have a positive correlation in reducing PCOS indicators 7
Recent Developments in Drug Treatment Strategies
Recent developments in drug treatment strategies for infertility in patients with PCOS include:
- The use of new gonadotropin formulations for in vitro fertilization (IVF) programs 6
- The elective embryo transfer in IVF cycles as a golden standard treatment for patients with PCOS at high-risk for ovarian hyperstimulation syndrome 6
- The current role of metformin administration in women with PCOS and infertility, and the choice between clomiphene citrate and letrozole as first-line treatment for ovulation induction 6
