Introduction
Hyperandrogenism with chronic anovulation & polycystic ovaries. Primarily a clinical diagnosis.[3]
Epidemiology
- most common cause of hyperandrogenicity in women
- by transvaginal ultrasonography, 20-25% of all women have > 8-10 subcapsular cysts in both ovaries
- prevalence 6.6% [7a]; 10% of reproductive age women[8]
Pathology
- enlarged polycystic ovaries with increased stroma & thickened capsule
- anovulation secondary to increased androgen which is converted to estrogen in adipose tissue
- hyperestrogen state stimulates pituitary resulting in increased LH:FSH ratio propagating anovulatory state
- loss of LH surge
- risk of endometrial hyperplasia is increased
- insulin-resistance
- defects in phosphorylation pattern of insulin receptor
Clinical manifestations
- amenorrhea or oligomenorrhea since menarche
- may manifest several years later[3]
- anovulatory infertility, irregular or missed menstrual periods
- hyperandrogenism
- hirsutism (70%)
- terminal hairs on the abdominal midline below the umbilicus
- acne (may be inflammatory)
- male balding patterm
- onset at puberty
- gradual onset, slow progression
- hirsutism (70%)
- truncal obesity (50%), insulin resistance
- body weight may be normal to obese
- ancanthosis nigricans
Diagnostic criteria
- 2 of 3 criteria + diagnosis of exclusion (see Differential diagnosis)
- anovulation (or oligo-ovulation)
- evidence of hyperandrogenism (hirsutism, acne)
- ultrasound findings of polycystic ovaries[3]
- imaging of adrenal glands & pelvis (NEJM)[25]
Laboratory
- serum FSH is normal
- serum LH is normal or increased
- progesterone challenge test induces withdrawal bleeding
- serum testosterone is normal or modestly (< 2-fold) increased
- increased serum prolactin (20-25%)
- serum DHEA-sulfate is mildly increased in 25% of patients
- serum estradiol levels are normal
- serum estrone levels are increased
- very high free testosterone & serum androstenedione suggest androgen-producing neoplasm
- increased serum insulin
- screen for dyslipidemia
- increased serum triglycerides[5]
- increased total serum cholesterol & LDL cholesterol[5]
- screen for diabetes mellitus: serum glucose, HgbA1c
- see ARUP consult[13]
Diagnostic procedures
Radiology
- pelvic &/or abdominal ultrasound
- symptom onset after menarche
- suspicion of ovarian or adrenal mass[3]
- serum testosterone > 150 ng/mL
- serum DHEA-sulfate > 7.0 ug/mL[3]
Complications
- increased risk of endometrial hyperplasia & carcinoma
- hypertension is common
- type 2 diabetes is common
- increased risk of metabolic syndrome
- obstructive sleep apnea
- increased risk for depression[10]
- excess risk for adverse pregnancy outcomes[12]
Differential diagnosis
- thyroid dysfunction
- adrenal hyperplasia
- hyperprolactinemia
- androgen-secreting neoplasm (rapidly progressive hirsutism or virilization)[3]
Management
- weight reduction through diet & exercise (1st line)
- oral contraceptives after ruling out pregnancy
- with or without spironolactone
- regulation of menses, improvement of acne[21]
- combined oral contraceptives (estrogen+progestin) suppresses androgen production[3]
- not better than metformin for treatment of hirsutism[21]
- spironolactone 50 mg daily reduces androgen levels[7]
- monitor for diabetes mellitus type-2
- metformin is the drug of choice
- metformin 500 mg TID may restore ovulation & fertility[4][6][25]
- inferior to letrozole for treatment of infertility in anovulatory women[25]
- delay pregnancy until diabetes mellitus is controlled[25]
- metformin reduces BMI & LDL cholesterol
- pioglitazone may also be useful[11]
- artemisinin degrades LONP1-CYP11A,1 an enzyme essential for ovarian production of androgens (investigational)[26]
- 1st line treatment of fertility in anovulatory women is letrozole[25]
- use letrozole or clomiphene for conception[3]
- long-acting GnRH analogues
- androgen inhibitors
- flutamide
- cyproterone
- letrozole may be more effective than clomiphene in stimulating ovulation & facilitating pregnancy[15]
- clomiphene previously used to stimulate ovaulation in women trying to become pregnant[3][25]
- for women who do become pregnant (not already diabetic)
- screen for gestational diabetes at the time of pregnancy diagnosis & at 24-28 weeks of pregnancy
- monitor blood pressure
- screen for obstructive sleep apnea & depression[10]
Comparative biology
- transplantation of brown adipose tissue reverses anovulation, hyperandrogenism, & polycystic ovaries in a DHEA-induced rat model of polycystic ovarian disease[20]
- administration of adiponectin rescues DHEA-induced polycystic ovarian disease phenotype in this rat model[20]
