Diagnostic Procedures
- Laboratory tests:
- Human chorionic gonadotropin (hCG): to evaluate for intrauterine pregnancy; would be negative in clients with PCOS
- Follicle stimulating hormone (FSH): to evaluate for menopause; typically slightly decreased or normal in clients with PCOS; if elevated concerns of post-menopause
- Luteinizing hormone (LH): to evaluate for ovarian tumors; elevated in 50 to 60% of clients with PCOS; concern for ovarian tumor with decreased levels
- LH/FSH ratio: to evaluate for premature primary ovarian failure; >2 in PCOS
- Prolactin: to evaluate for pituitary tumors and Cushing's; slightly elevated in some women with PCOS (levels 20 to 200 micrograms/L)
- 24-hour urine free cortisol: to evaluate for Cushing's; mild elevations in PCOS; if >2 times upper limit of normal more consistent with Cushing's
- Thyroid stimulating hormone (TSH): to evaluate for thyroid dysfunction; typically normal in clients with PCOS
- Estradiol (E2): to evaluate for premature primary ovarian failure or prolactinoma; typically slightly decreased with PCOS
- Androgens: to help confirm PCOS and exclude androgen producing tumors
- Dehydroepiandrosterone sulfate (DHEA-S): to evaluate for Cushing's ovarian tumor or menopause; typically normal or slightly elevated with PCOS; concerns with moderate elevations (Cushing's or ovarian tumor) or decreased levels (menopause)
- Total testosterone: to evaluate for adrenal disorders or tumors; typically normal or slightly elevated with PCOS; moderate elevations (>200ng/dL) concerns for tumor
- Sex hormone binding globulin (SHBG): to evaluate for tumors; typically suppressed with PCOS; if levels elevated concerns for tumor
- Free androgen index (FAI): typically elevated with PCOS
- 17 hydroxyprogesterone: to evaluate for adrenal tumor or ovarian cancer; decreased with PCOS; concerns with elevated levels
- 2-hour 75 g oral glucose tolerance test (OGTT) if BMI >28: to evaluate for glucose intolerance or diabetes mellitus
- Fasting lipid profile(FLP): to evaluate for hyperlipidemia secondary to hyperandrogenism; may be elevated with PCOS
- C-reactive protein (CRP) fibrinogen homocysteine: may be elevated since PCOS patients have higher incidence of proinflammatory and atherogenic markers than non-PCOS patients placing them at higher risk for cardiovascular disease (CVD) (PCOSWC 2005).
(Costello 2005; ACOG Practice Bulletin 2003; Sheehan 2004)
- Diagnostic procedures:
- Pelvic ultrasound preferably transvaginal ultrasound: frequently shows ovaries of increased size due to either a greater number of follicles/cysts (12 or more follicles measuring 2 to 9 mm in diameter) or an increased ovarian volume. Findings may be nonspecific as in women taking oral contraceptive pills in non-obese women or in women without symptoms of anovulation or hyperandrogenism (Balen et al. 2003; Costello 2005; ACOG Practice Bulletin 2003; Allemand et al. 2006; Hassan & Killick 2003; Hart Hickey & Franks 2004).
- Endometrial biopsy: unopposed estrogen from chronic anovulation (greater than 5 months) puts PCOS patients at higher risk for endometrial hyperplasia and cancer (Fraser & Kovacs 2004; Richardson 2003).
Criteria for Diagnosis
- Rotterdam Criteria: two of the following in addition to exclusion of related disorders:
- Oligo- or anovulation
- Clinical and/or biochemical signs of hyperandrogenism
- Polycystic ovaries
(The Rotterdam ESHRE/ASRM-Sponsored PCOS Consensus Workshop Group 2004)
Differential Diagnoses
- Androgen secreting tumors of the ovary or adrenal gland
- Hypogonadotropic hypogonadism (nutrition excessive exercise chronic disease)
- Pituitary tumor and other prolactin disorders
- Cushing's syndrome
- Nonclassic congenital adrenal hyperplasia
- Acromegaly
- Genetic defects in insulin action
- Primary hypothalamic amenorrhea
- Primary ovarian failure
- Thyroid disease
- Exogenous androgens
(ACOG Practice Bulletin 2003; Sheehan 2004; Lane 2006; Schroeder & ACOG 2003)
Management
Management techniques are individualized to patient symptoms and goals. Overall treatment factors include ovulation induction normalization of the endometrium prevention of symptomatic hyperandrogenism and reduced insulin resistance (Buccola & Reynolds 2003).
Step 1 – Patient and Family Education
- Explain diagnosis. PCOS is a heterogeneous condition caused by many factors and involves several genes. Much of the pathophysiology is not fully understood. Hypotheses include the following: 1) dysfunction of gonadotropin-releasing hormone and luteinizing hormone resulting from hypothalamic-pituitary abnormalities; 2) enzyme defect in ovarian and adrenal steroid production; 3) metabolic dysfunction characterized by insulin resistance and compensatory hyperinsulinemia that adversely affect the hypothalamus pituitary ovaries and adrenal glands. Infertility is due to impaired follicular development associated with FSH deficiency. Teaching should include contraception methods since return of fertility is an expected goal of treatment (PCOSWC 2005; Van der Spuy & Dyer 2004; Fraser & Kovacs 2004). Evidence Fair Recommendation C
- Explain risks associated with PCOS.
- Increased cardiovascular risk results from several mechanisms including changes in blood vessel function abnormal coagulation elevated atherogenic markers (CRP fibrinogen homocysteine) decreased antioxidant capacity elevated serum lipids and hypertension (Cattrall & Healy 2004; PCOSWC 2005; ACOG Practice Bulletin 2003; Sheehan 2004). Evidence Fair Recommendation C
- Patients with PCOS are at increased risk for type 2 diabetes (risk is as high as 5 to 10 times that of general population). Age of onset occurs as early as 3rd or 4th decade. 30% of women with PCOS have impaired glucose tolerance (Cattrall & Healy 2004). Evidence Fair Recommendation C
- Cancer risk linked to PCOS has not been demonstrated with good quality of evidence; however there appears to be a higher risk for endometrial breast and ovarian cancer in PCOS patients. The main theory that supports increased cancer risk involves that of unopposed estrogen stimulation (Cattrall & Healy 2004; Fraser & Kovacs 2004). Evidence Fair Recommendation C
- Pregnancy-related risks include infertility miscarriage and gestational diabetes. The exact pathogenesis of miscarriage is not clearly defined and appears to be the result of several interrelated factors including elevated LH levels hyperandrogenemia insulin resistance obesity and abnormal follicular growth (Jakubowicz et al. 2002; Nestler et al. 2002; ACOG Practice Bulletin 2003) Evidence Fair Recommendation C
- Depression and anxiety are long-term risks of PCOS due to infertility and negative cosmetic effects (Richardson 2003). Evidence Fair Recommendation C
- Establish treatment goals. Return of menses and fertility absence of hirsutism and prevention of complications. Evidence Fair Recommendation C
Step 2 – Non-pharmacological Treatment
- Diet exercise weight loss. Treatment should begin with lifestyle modification with emphasis on controlled eating patterns (reduced fat intake and increased fiber) and regular aerobic exercise to achieve weight control. This is the best first line intervention for patients with a BMI greater than 26. Weight loss from lifestyle modification alone has caused resumption of regular menstruation decreased LH levels induction of ovulation improved fertility decreased androgens improvement of insulin resistance and decreased risk for diabetes and cardiovascular disease. Smoking cessation should also be addressed to reduce cardiovascular risk. Weight reduction may minimize long-term cancer risk (ACOG Practice Bulletin 2003; PCOSWC 2005; Pasquali et al. 2003; Guzick 2004; Cattrall & Healy 2004; Sheehan 2004). Evidence Fair Recommendation A
- Routine screening. All patients should be screened for hypertension glucose intolerance with 2-hour 75g OGTT and for dyslipidemia with fasting lipid profile (FLP) (ACOG Practice Bulletin 2003; PCOSWC 2005). Evidence Good Recommendation A
- Cosmetic therapies. Options for hirsutism include bleaching plucking shaving electrolysis and laser therapy; these are effective to some degree. These may involve significant expense localized skin irritation and scarring and long term time commitment (Buccola & Reynolds 2003; Sheehan 2004; PCOSWC 2005). Evidence Fair Recommendation B
Step 3 – Pharmacological Treatment
There are no U.S. Food and Drug Administration (FDA)-approved drugs indicated for the treatment of PCOS and any drug intervention will be an off-label application (Yildiz 2004).
- Combined oral contraceptives (COC): Appropriate for first-line treatment and long-term management. Mechanisms of action include suppression of LH secretion from the pituitary and increased circulating SHBG. Treatment is aimed at suppressing hyperandrogenism restoring menstrual regularity preventing endometrial hyperplasia preventing pregnancy possibly improving lipid levels and treating acne and hirsutism (ACOG Practice Bulletin 2003; PCOSWC 2005). Controversy exists regarding COCs as first line use in PCOS due to their detrimental effect on insulin sensitivity and this is currently being studied (Morin-Papunen et al. 2003). Additionally use of non-androgenic 3rd-generation progestins such as norgestimate or desogestrel or anti-androgens such as drospirenone is recommended as they have shown to cause less detrimental effects on glucose insulin and lipids. (Yildiz 2004; Bruni et al. 2003). Further studies are warranted though as it is unknown currently whether certain oral contraceptives are better than others (ACOG Practice Bulletin 2003). Evidence Fair Recommendation B
- Medroxyprogesterone acetate: 10 mg for 7 to 10 days every (Q) 1 to 3 months. Action: to induce menses reduce endometrial hyperplasia and restore menstrual regularity. This treatment does not affect androgen levels yet normalizes endometrial growth and therefore prevents the associated risk for endometrial cancer (Lane 2006; Stout & Fugate 2005; Richardson 2003). Evidence Good Recommendation B
- Insulin sensitizers: to improve insulin sensitivity inhibit gluconeogenesis improve menstrual regularity and ovulation and reduce androgen synthesis. These also act synergistically with clomiphene for inducing ovulation and menstrual regularity.
- Metformin: improves hyperinsulinemia hyperandrogenism menstrual cyclicity and causes ovulation. Through reducing insulin levels there is decreased insulin-mediated ovarian androgen production increased SHBG synthesis (which insulin blocks from the liver) reduced LH/FSH ratio reduced LH reduced 17-OHP and decreased levels of free androgens (Tan Yap & Tan 2001; Genazzani et al. 2004). Positive effects on pregnancy have been demonstrated in a prospective case control study (Glueck et al. 2002). A retrospective study reported lower incidence of first-trimester pregnancy loss with metformin use (Jakubowicz et al. 2002). There are less pronounced effects on hirsutism than COCs or antiandrogens. Not FDA approved for PCOS but much support in medical literature. Metformin does improve cardiovascular risk factors which also lends support to its use. Long-term safety and effectiveness is yet to be demonstrated (Cattrall & Healy 2004; Sheehan 2004; Kelly & Gordon 2002; Nestler et al. 2002; Pasquali et al. 2003; PCOSWC 2005; ACOG Practice Bulletin 2003; Lord Flight & Norman 2003). Evidence Good Recommendation B
- Thiazolidinediones (TZDs) (pioglitazone and rosiglitazone): Another class of insulin-sensitizers that are less well-studied. Improved hyperinsulinemia-mediated ovarian androgen production decreased plasma and free testosterone levels and increased sex hormone binding globulin (SHBG) levels (Tan Yap & Tan 2001). TZDs have been shown to improve hyperandrogenism and cause ovulatory cycles but their use is considered investigational at this time (Stout & Fugate 2005; PCOSWC 2005). A recent randomized controlled trial (RCT) showed pioglitazone to be as effective as metformin in improving insulin resistance and hyperandrogenism in women with PCOS however pioglitazone caused increases in body weight BMI and waist to hip ratio (Ortega-Gonzalez et al. 2005). Troglitazone was shown to improve hirsutism by 17% but has since been removed from the market due to liver toxicity (Azziz et al. 2001). Evidence Poor Recommendation I
- Antiandrogens: The following antiandrogens have all proven effective treatment alone for hirsutism so their use is indicated if COC use is contraindicated although birth control is needed as all have teratogenic potential. When used with COC antiandrogens work synergistically by suppressing androgen levels through different mechanisms.
- Spironolactone (50 to 200 mg/d) possesses intrinsic hormonal activity and interferes with steroidogenesis.
- Flutamide (250 mg/day) acts at the androgen receptor sites as a pure antiandrogen
- Finasteride (2.5 to 5 mg/day) 5-alpha-reductase inhibitor for treatment of androgenic alopecia; blocks the enzyme responsible for converting testosterone to its active metabolite dehydrotestosterone. Low dose (2.5 mg) as effective as high dose (5 mg) (Bayram et al. 2002; ACOG Practice Bulletin 2003; PCOSWC 2005; Christy Franks & Cross 2005).Evidence Fair Recommendation C
- Eflornithine: Topical agent for hirsutism inhibits the enzyme ornithine decarboxylase. Slows hair growth but does not remove hair. Has not been studied specifically in PCOS patients but has been proven effective for treatment of unwanted facial hair for women. Is well-tolerated with notable benefit after 6 months of use. Not covered by insurance so cost may be an issue. (Sheehan 2004; ACOG Practice Bulletin 2003; Balfour & McClellan 2001). Evidence Good Recommendation B
- Ovulation inducers to provide pharmacological levels of FSH:
- Clomiphene citrate: 50 to 100 mg/day for 5 days at beginning of cycle. Restores menstrual regularity prevent endometrial hyperplasia and induce ovulation by stimulating the release of pituitary gonadotropins. Traditional first-line treatment for anovulatory women who wish to conceive. 80% will ovulate in response to treatment and 50% of those will conceive. Of those who respond 50% do so with the 50-mg daily starting dose another 20% with the 100-mg daily dose. Pregnancy response usually occurs within the first six ovulatory cycles. Prolonged duration of treatment does not significantly increase rate of pregnancy however adding another agent can increase ovulation rates (ACOG Practice Bulletin 2003). Evidence Good Recommendation B
- Combination of clomiphene with metformin is more effective than either agent used alone to restore ovulation and achieve pregnancy. In patients who are resistant to clomiphene metformin may also be effective in restoring responsiveness to clomiphene (Costello 2005; George et al. 2003; Kocak et al. 2002; Nestler et al. 2002; Vandermolen et al. 2001).
Evidence Good Recommendation B
- Combination of clomiphene with metformin is more effective than either agent used alone to restore ovulation and achieve pregnancy. In patients who are resistant to clomiphene metformin may also be effective in restoring responsiveness to clomiphene (Costello 2005; George et al. 2003; Kocak et al. 2002; Nestler et al. 2002; Vandermolen et al. 2001).
- Tamoxifen: 5 to 40 mg/day for 4 days at beginning of cycle. Non-steroidal selective estrogen receptor modulator. Not FDA approved for ovulation induction (off-label use). Shown to have similar efficacy as clomiphene in a controlled observational study (Nardo 2004). Evidence Poor Recommendation I
- Exogenous gonadotropins:
- Urinary follicle stimulating hormone (uFSH) (Metrodin ®) and recombinant FSH (rFSH) (Gonal F® and Puregon®). Both uFSH and rFSH are equally effective in inducing ovulation in women who are resistant to clomiphene; uFSH has smaller amounts of urinary proteins which lowers incidence of adverse reactions (local allergy or hypersensitivity). Risks of both include multiple follicle development multiple pregnancies and ovarian hyperstimulation syndrome; risks can be reduced by using lower doses. Lower dosing has also been shown to be more effective. The most frequently used dosing schedules are low dose step up and step down regimens. Higher costs are associated with rFSH (Bayram van Wely & van der Veen. 2001; ACOG Practice Bulletin 2003). Evidence Fair Recommendation B
- Human menopausal gonadotropin (hMG). Contains FSH luteinizing hormone (LH) and large quantities of potentially allergenic urinary proteins. Has been associated with increased risk of ovarian hyperstimulation syndrome (Bayram van Wely & van der Veen 2001; Tan Yap & Tan 2001). Evidence Fair Recommendation C
- Clomiphene citrate: 50 to 100 mg/day for 5 days at beginning of cycle. Restores menstrual regularity prevent endometrial hyperplasia and induce ovulation by stimulating the release of pituitary gonadotropins. Traditional first-line treatment for anovulatory women who wish to conceive. 80% will ovulate in response to treatment and 50% of those will conceive. Of those who respond 50% do so with the 50-mg daily starting dose another 20% with the 100-mg daily dose. Pregnancy response usually occurs within the first six ovulatory cycles. Prolonged duration of treatment does not significantly increase rate of pregnancy however adding another agent can increase ovulation rates (ACOG Practice Bulletin 2003). Evidence Good Recommendation B
- Lipid-lowering medications: Suppression of androgens is associated with elevated lipids. When dietary and exercise measures have been tried first then use of appropriate medications is warranted (statin fibrate niacin ezetimibe or some combination of these medications) (ACOG Practice Bulletin 2003; POCSWC 2005). Evidence Fair Recommendation B
- Blood pressure lowering medications and aspirin: Treat elevated blood pressure with appropriate medications and add aspirin as appropriate for reduction of cardiovascular risk (PCOSWC 2005). Evidence Good Recommendation A
Step 4 – Surgery / Referral
- Surgical laparoscopic ovarian drilling/electrocautery: Laparoscopic electrocautery of the ovaries is effective for ovulation induction. This procedure is indicated for patients resistant to or suffering side effects with clomiphene citrate patients in whom gonadotropin therapy has failed or patients with ovarian hyperstimulation from either clomiphene or gonadotropins. When comparing electrocautery to gonadotropin therapy (rFSH) there have been no differences shown in ovulation rates pregnancy rates live birth rates or miscarriage rates. There is a lower risk of multiple pregnancies with electrocautery. Studies have also shown that ovarian electrocautery resulted in decreased resistance to clomiphene citrate and greater efficacy of recombinant FSH following surgery. Electrocautery may be more cost-effective due to multiple pregnancy rates of gonadotropin use. Risks include adhesion formation and potential surgical risks (bleeding and infection) anesthesia risks and premature ovarian failure (theoretical complication) (Bayram et al. 2004; Farquhar et al. 2002; Farquhar 2004; Farquhar et al. 2005). Evidence Good Recommendation B
- Referral to specialist: Specialty referral depends on the expertise of the clinician. Consider referral under the following circumstances:
- Abnormal unexplained vaginal bleeding or very heavy bleeding
- Anovulatory dysfunctional bleeding not responding to medications
- Suspicion of other hyperandrogen disorders needing exclusion
- Severe hyperlipidemia
- Diagnosis of type 2 diabetes
- Recurrent miscarriages
- Infertility management especially when other factors co-exist such as male infertility
- Patient intolerant of usual treatments
- Treatment failure

Step 5 – Follow Up
Follow up depends on individual signs and symptoms and treatment regimens
- Regular follow up every 6 months to monitor weight blood pressure fasting glucose and lipids
- Breast exam Pap smear mammogram as recommended for all women
- Anti-androgen therapy: every 3 to 6 months initially
- Progestin therapy for anovulatory dysfunctional uterine bleeding: every 3 to 6 months initially
- In women trying to conceive if no pregnancy occurs after 6 months additional infertility evaluations are performed. When no pregnancy occurs 9 to 12 months after return of ovulation intrauterine insemination is considered if appropriate then gonadotropins and in vitro fertilization.

Type of Evidence supporting the Recommendations
The type of supporting evidence is identified and graded for selected recommendations (see the "Major Recommendations" field).
These guidelines are based on sources such as research studies (randomized controlled trials retrospective cohort studies prospective case studies case control studies and controlled observational studies) meta-analysis reviews systematic literature reviews expert opinion and practice guidelines and position statements from professional organizations (American College of Obstetricians and Gynecologists Practice Bulletin and American Association of Clinical Endocrinologists position statement).
Potential Benefits
- Improved identification and management of patients with polycystic ovary syndrome
- Improved quality of life for patients with polycystic ovary syndrome:
- Return of menses
- Return of fertility
- Absence of hirsutism
- Prevention of complications (obesity diabetes cancer heart disease pregnancy complications and depression)
Potential Harms
- Adverse effects of medications (see original guideline document for more information)
- Cosmetic therapies may involve significant expense localized skin irritation and scarring and long term time commitment.
- Risks of electrocautery include adhesion formation and potential surgical risks (bleeding infection and anesthesia risks) and premature ovarian failure (theoretical complication).
