MODERN APPROACH TO PCOS J. SERNA MD. PhD. IVI Madrid
Physiology and Diagnosis • What is PCOS? • How to Diagnose it? • How to Treat it?
High prevalent disease • Multiorganic: ovaries, HH, adrenal, fat, skin, pancreas, etc... • Different degrees of organ involvement • Main feature: ovarian hyperandrogenism • Multiple phenotypes
Metabolic disorders • IR and Hyperinsulinism • Obesity (male pattern) • Impaired Glucose Tolerance and DM2 • Hyperlypemia PCOS: HETERGENEOUS • Reproductive disorders • Hyperandrogenism • Anovulation: Menstrual disorders, infertility • Polycystic ovaries • Miscarriage • General Health Disorders • Acantosis nigricans • Cardiovascular disease • Endometrial cancer
PCOSDg CRITERIA • Anovulation and/or dysovulation • Clinical and/or Biochemical Hyperandrogenism • Polycystics ovaries • and exclusion of other aetiologies (CAH, • tumours, HPRL, etc) • The Rotterdam ESHRE/ASRM sponsored PCOS consensus workshop group, 2003

Percentage of patients with PCOS and altered biochemical markers
PCOS DIAGNOSIS • Biochemical hyperandrogenism • Normal boundaries established by laboratories RIA: • 95-97% • Control population? • High variability among normal population (absence of feed-back mechanism) • Diverse androgens: TT,ITL, 17OHP, DHA-S, A4, etc.
PCOS • Anovulation and/or dysovulation • Clinical and/or Biochemical Hyperandrogenism • Polycystics ovaries • and exclusion of other aetiologies (CAH, tumours, HPRL, etc) • The Rotterdam ESHRE/ASRM sponsored PCOS consensus workshop group, 2003
PCOS DIAGNOSIS Polycystic ovary Presence of 12 or more follicles 2-9 mm and/or ovarian volume higher than 10 mL (one ovary is enough) Non suitable to women on OCP or with a dominant follicle (>10 mm) The Rotterdam ESHRE/ASRMsponsored PCOS consensus workshop group, Hum Reprod 2004,19:41-7
Polycystic ovaries. Pitfalls False positives: 20% normal women False negatives: 30% PCOS US scan cannot make differential diagnosis between multycystic ovaries and polycystics ovaries Time required for measurements

Insulin-resistance in PCOS patients 75,3%(n=149) N=198 HOMA (Homeostasis model assesment): Glucose x18,1/Insulin x0,139 (Insulin-resistance: Obese <5,09, Lean <5,48)

Methods for Insulin-Resistance work-up • Gold Standard test IR is euglucemic clamp • . • Due to its complexity, Oral Glucose Tolerance Test or Basal Glucose and Insulin measurements instead • . • OGTT is the main test in the diagnosis of Impaired Glucose Intolerance or Type II Diabetes • Other indexes are less used in clinical routine

Cardiovasculardisease in women • Near2,5 million women hospitalized each year due to CVD • 1st death cause in women (over the next 14 together) • Half of these deaths are from MCI • Annual cost estimated to be 28,65 billion dolars • Tsang y cols. Risk of caronary heart disease in women: current understanding. Mayo Found Med Educ Research, 2000
Clinical hyperandrogenism • Different prevalence among different populations: ethnicity • Absence of consensus on how to evaluate clinically the hyperandrogenism • Semiquantitative staging methods (Ferriman-Gallwey). Limitations: • Subjective: intra and inter-observer variability • Previous pharmacological or cosmetical treatments • Non validated

Laparoscopic Electrocoagulation Laparoscopic Ovarian Diathermy Several energy sources: Monopolar, LASER (CO2, Argon, KTP, YAG) Mechanism of action • Not well established • Removal of androgen-producing stroma • Total and free testosterone reduction to 40-50% basal levels • LH pulses amplitude decreases • Better prognosis for patients with LH > 10 UI/l before surgery
