II. Epidemiology

  1. Prevalence: 7% of reproductive-aged women in U.S. (most common endocrinopathy in this group)

III. Pathophysiology

  1. History
    1. First described by Stein and Leventhal in 1935
  2. Contributing Factors
    1. Obesity and hyperinsulinemia
    2. Increased adrenal function
  3. Androgen Excess (Hyperandrogenism)
    1. Androstenedione increased
    2. Testosterone increased
    3. Free Testosterone increased
      1. Occurs with decreased Sex Hormone Binding Globulin
  4. Ovarian enlargement with Hyperthecosis
    1. Luteinization of theca interna
    2. Reduction of granulosa cells

IV. Symptoms

  1. Menstrual Disorders (80% of PCOS patients)
    1. Oligomenorrhea (36 to 180 day cycles) or Amenorrhea
    2. Anovulatory Bleeding (<6 Menses per year)
    3. Delayed menstrual regularity
  2. Infertility (74% of patients) or Recurrent Miscarriage
  3. Androgenic features
    1. See Hyperandrogenism
    2. Acne Vulgaris
    3. Hirsutism (69%)
    4. Male sweat changes
    5. Clitoris swelling
  4. Central Obesity (49% of PCOS patients)
    1. Weight gain starts in teens and twenties
    2. BMI over 27 (65% of PCOS patients)

V. Signs

  1. Hypertension
  2. Hirsutism
  3. Acne Vulgaris
  4. Alopecia
  5. Acathosis nigricans
  6. Skin Tags
  7. Bilateral ovary enlargement

VI. Differential Diagnosis (See Hyperandrogenism)

  1. HAIR-AN Syndrome
  2. Cushing's Syndrome (buffalo hump, striae)
    1. Obtain 24 hour Urine Cortisol (or Dexamethasone Suppression Test)
  3. Congenital Adrenal Hyperplasia (severe Virilization)
    1. Serum DHEAS > 700 ng/dl (Androgen secreting tumor)
    2. Serum Total Testosterone >20 ng/dl (Androgen tumor)
    3. Obtain pelvic Ultrasound and Adrenal CT or MRI
  4. Primary Ovarian Insufficiency (Hot Flashes, atrophic urogenital symptoms)
    1. Serum FSH
    2. Serum Estradiol
  5. Hypothalamic Amenorrhea (e.g. Female Athlete Triad with low BMI, Eating Disorder, athlete)

  7. Cardiovascular Disease
  8. Mood Disorders (e.g. Major Depression, Generalized Anxiety)

VIII. Imaging: Transvaginal Ultrasound

  1. Indications
    1. Ultrasound is not required for diagnosis of PCOS (diagnosis can be made clinically)
    2. Obtain if Rotterdam Criteria not met or ovarian pathology suspected (e.g. Ovarian tumor)
  2. General features
    1. At least 12 (25 if new technology used) small follicles (2-9 mm diameter each) in various stages
    2. Ovary >10 ml in volume
    3. Thick ovarian capsule
    4. String of pearls appearance
  3. Criteria: Multiple Ovarian Cysts (seen in 80% of cases)
    1. Ten or more cysts in a single plane
    2. Each cyst <10 mm in diameter
    3. Dense stroma
  4. Interpretation
    1. Polycystic appearance is seen in up to 62% of women with normal Ovulation
    2. Polycystic appearance does not diagnose PCOS
    3. PCOS clinical features must be present for diagnosis
    4. Hassan (2003) Fertil Steril 80:966-75 [PubMed]

IX. Labs: Approach

  1. Consider Hyperandrogenism labs (if not evident from exam or severe Virilization of Congenital Adrenal Hyperplasia)
    1. Serum DHEAS > 700 ng/dl (Androgen secreting tumor)
    2. Serum Total Testosterone >20 ng/dl (Androgen tumor)

    1. Urine Pregnancy Test
    2. Thyroid Stimulating Hormone
    3. Morning 17a-hydroxyprogesterone (adrenal hyperplasia)
    4. Serum Prolactin
  3. Evaluate comorbid disease
    1. Blood Pressure
      1. Obtain at each visit

Definition (MEDLINEPLUS)

Polycystic ovary syndrome (PCOS) happens when a woman's ovaries or adrenal glands produce more male hormones than normal. One result is that cysts (fluid-filled sacs) develop on the ovaries. Women who are obese are more likely to have polycystic ovary syndrome.

Symptoms of PCOS include:

  • Infertility
  • Pelvic pain
  • Excess hair growth on the face, chest, stomach, thumbs, or toes
  • Baldness or thinning hair
  • Acne, oily skin, or dandruff
  • Patches of thickened dark brown or black skin

Women with PCOS are at higher risk of diabetes, metabolic syndrome, heart disease, and high blood pressure.Medicines can help control the symptoms. Birth control pills help women have normal periods, reduce male hormone levels, and clear acne. Other medicines can reduce hair growth and control blood pressure and cholesterol. There is no cure.

NIH: National Institute of Child Health and Human Development
Definition (NCI) A disorder that manifests as multiple cysts on the ovaries. It results in hormonal imbalances and leads to irregular and abnormal menstrual periods, excess growth of hair, acne eruptions and obesity.
Definition (NCI_NCI-GLOSS) A condition marked by infertility, enlarged ovaries, menstrual problems, high levels of male hormones, excess hair on the face and body, acne, and obesity. Women with PCOS have an increased risk of diabetes, high blood pressure, heart disease, and endometrial cancer.
Definition (NCI) A non-neoplastic disorder characterized by bilateral polycystic and enlarged ovaries. Clinical signs include amenorrhea, oligomenorrhea, infertility, obesity, hirsutism, and virilism.
Definition (MSH) A complex disorder characterized by infertility, HIRSUTISM; OBESITY; and various menstrual disturbances such as OLIGOMENORRHEA; AMENORRHEA; ANOVULATION. Polycystic ovary syndrome is usually associated with bilateral enlarged ovaries studded with atretic follicles, not with cysts. The term, polycystic ovary, is misleading.
Definition (CSP) clinical symptom complex characterized by presence of multiple cysts on the ovaries, oligomenorrhea or amenorrhea, anovulation and regularly associated with excessive amounts of body hair (hirsuitism), excessive body weight, infertility and insulin resistance.
