Polycystic Ovarian Syndrome
  • 1st described by Irving Stein and Michael
    Leventhal as a triad of amenorrhea, obesity and
    hirsutism (1935)
  • The most common endocrine disorder in women of
    reproductive age 2-8 of women
  • Current suggested prevalence in the U.S.
  • Caucasian 4.8
  • African American 8.0
  • Hispanic or Latino 13
  • 5-10 of women

Review Objectives
  • Symptom Presentation
  • Diagnosis Definitions
  • Potential Causes
  • Metabolic and Reproductive Complications
  • Infertility

4
PCOS Presentation
  • Two of the following symptoms
  • Polycystic ovaries (PCO)
  • Hyperandrogenism
  • Anovulation
  • No single criteria is sufficient for clinical
    diagnosis.
  • Additional features may include
  • Excessive hair growth Abnormal bleeding
  • Obesity Hair loss
  • Acne
  • Infertility

PCOS Presentation
  • Difficult to diagnosis
  • Heterogeneous symptoms
  • Vary over time
  • NIH-Sponsored Conference on PCOS (1990 Criteria)
  • Rotterdam ESHRE/ASRM-Sponsored PCOS Consensus
    Workshop Group (2003 Criteria)

Early Signs Adolescence
  • Polycystic ovarian syndrome is the most common
  • endocrinopathy in adult women, and is emerging
    as a common
  • cause of menstrual disturbances in the
    adolescent population
  • Normal pubertal events include
  • Oligomenorrhea, hirsutism, acne, and weight
    gain
  • Insulin resistance has reportedly increased in
    last decade
  • Pediatric Endocrinologists trending towards an
    earlier work-up then compared to traditional
    practice of waiting 2-years post-menarche

Endocrinology Metabolism, 2005.
9
Genetic Link
  • Familial clustering of PCOS common
  • 1st degree relatives of patients with PCOS may be
    at high risk for diabetes and glucose intolerance
  • Mothers and sisters of PCOS patients have higher
    androgen levels than control subjects

Yildiz BO et al, Journal of Clinical
Endocrinology Metabolism, 2003.
PCOS is a genetically determined ovarian
disorder the heterogeneity can be
explained on the basis of interaction of the
disorder with other genes and with the
environment.
Franks S et al, International Journal of
Andrology, 2006.
10
PCOS Metabolic Disorder
  • Insulin Resistance
  • High association with PCOS
  • 10 have Type 2 Diabetes
  • 30-35 have Impaired Glucose Tolerance (IGT)
  • Obesity
  • 50 of PCOD patients are obese
  • Amplifies biochemical and clinical abnormalities
    of PCOS

11
PCOS Metabolic Disorder
  • Endometrial Cancer
  • Long-term follow-up of 786 PCOS women found an
    increased risk of endometrial cancer
  • Women gt50 yrs of age with endometrial cancer,
    PCOS (62.5) more prevalent than not (27.3
    P0.033)
  • Cardiovascular Disease
  • PCOS is characterized by endothelial dysfunction
    and resistance to vasodilating action of insulin
  • Increased risk of myocardial infarction in PCOS
    women than age-matched controls

12
PCOS Metabolic Disorder
  • Sleep Apnea
  • Increased Sleep Disordered Breathing (SDB) and
    daytime sleepiness in PCOS vs. controls
  • Depression
  • Higher prevalence in PCOS patients, associated
    with higher body mass index (BMI, P0.05) and
    greater insulin resistance (P0.02)

Pregnancy Complications
  • Spontaneous Abortions
  • Increased in high BMI/PCOS patients
  • Impaired Glucose Tolerance
  • Gestational Diabetes
  • Hypertension
  • Small for Gestational Age

Infertility
  • gt75 of women with anovulation infertility
  • Follicular arrest
  • Impaired selection of dominant follicle
  • Risk of multiple pregnancy with treatment

15
PCOS Weight Loss
  • Frequency of obesity in women with anovulation
    and PCO 30-75
  • Six month weight-loss program for overweight
    anovulatory women
  • Lost an average of 6.3 kg (13.9 lbs)
  • Decreased fasting insulin and testosterone levels
  • 92 resumed ovulation (12/13)
  • 85 became pregnant (11/13)

16
Infertility Treatments
  • Step-by-step. . . .
  • If BMI elevated, loss of at least 5 body weight
  • Ovulation induction (OI) with clomiphene citrate
  • Insulin sensitizer as single agent
  • Insulin sensitizer clomiphene
  • Gonadotropin therapy, FSH hormone
  • Gonadotropins insulin sensitizer
  • In vitro fertilization (IVF) single embryo
    transfer

Kim LH et al, Fertility and Sterility, 2000.
17
PCOS Stimulated Cycles
  • PCOS patients are often high responders to
    medications,
  • Clomid and FSH
  • High risk of multiple pregnancy
  • Ovarian hyperstimulation syndrome (OHSS)
  • IVFsingle embryo transfer

Conclusions
  • PCOS is a multifaceted condition
  • Varying presentations
  • Begins in adolescence
  • Long-term consequences
  • Genetic and pre-natal implications
  • Metabolic Disorder
  • Cosmetic issues
  • Reproductive complications. cycle irregularity /
    bleeding / endometrial cancer
  • Infertility
  • Common endocrinopathy in pre-menopausal women,
    causing menstrual irregularities and hirsutism
  • Multiple treatments available with potentially
    successful outcomes
