Presenting complaints Goldzieher

PCOS Diagnosis NIH 1990 Rotterdam Androgen Excess Society Hyperandogenism R NR R Oligo/amenorrhe a R NR NR PCO NR NR

Signs & symptoms of Hirsutism androgen excess Htn Acne Tachycardia Oily skin Male body habitus Anovulation **Time/duration important Voice deepening Balding Clitoromegaly Increased libido Precocious puberty Acanthosis nigricans

The PCO PCO in one or both ovaries 12 or more follicles measuring 2-9mm Ovarian volume > 10cm3 Repeat scan if volume unable to be calculated due to cyst, single ovary can meet definition

BP BMI, waist circumference (>35 abn) Hyperandrogenism stigmata Hyperinsulinemia stigmata

Suggested by ACOG Hormonal T tot, SHBG or bioavailable & free T TSH Prolactin 17OHP (random <4, follicular morning fasting < 2ng/mL?Cushing s screen & acromegaly screen 2 h GTT Metabolic 2h GTT Fasting Lipids Ultrasound PCO Endometrial evaluation Optional consideration Gonadotropins to exclude alternate etiology of oligo or amenorrhea Fasting insulin Cushing s

17OHP? 21 hydroxylase or CYP21 Prevalence in USA Ashkenazi Jewish Hispanics Yugoslavs Native American Inuits Italians Specificity reduced in luteal phase Morning fasting follicular Elevated ACTH stim test

Diagnosis of Exclusion: also known as: So, did I miss

Fasting glucose or 2hGTT? Legro 1999

AES Suggest 2h GTT if: Obesity FH T2DM Hx GDM Age > 40 JCEM 2010; 95:2038-49

Insulin Hypothalamic Decr SHBG Direct trophic stimulation Abnormal appetite Incr GnRH pulse, LH downstream Incr Bio T Adrenals Ovaries

Quick Diabetes Review Normal glucose metabolism Hyperinsulinemia Impaired glucose tolerance Diabetes Type 2 Loss of pancreatic insulin secretion

Reproductive Uterine health PCOS CVD DM

Reproductive Pregnancy Risks Infertility Risks GDM Hypertensive D/O Multifetal Risks Incr OHSS Incr Multiples

Uterine health Irregular menstrual bleeding Menorrhagia Ablation? - reconsider Endometrial hyperplasia Prevention? Correct P4 dosage?, Metformin?, Mirena? Progestin LARC Is this a better option than tubal ligation?

Diabetes Prospective cohort > 30yo 11.9% DM vs. 1.4% controls Up to 40% of PCOS women could be insulin resistant Conversion to impaired glucose tolerance up to 20% per year 3-10% undiagnosed DM rate

Dyslipidemia Borderline or high lipids 70% Suspect increased risk, no prospective studies Nurse s Health Study increased dose-response risk of CVD w/ increasing oligomenorrhea, PCOS sx Increased subclinical atherosclerosis

Additional considerations Depression Sleep Apnea Hirsutism Acne Alopecia NAFLD

Weight loss Reduced androgens Menstrual frequency increases PR increases Hirsutism decreased Glucose utilization improves Lipid normalization As little as 5% weight loss may help (obvious limitations of this classically reported number)

Are combined HC ok? Do not appear to increase r/o DM Consider other risk factors Obesity, clotting history, smoking, htn

SHBG 80% of T is bound to SHBG Liver Increased by E Decreased by androgens, progestins & insulin 19% bound to albumin 1% free & active ASD, DHEA, DHEAS not bound

DHT Testosterone 5α reductase 3α-keto-reductase DHT 3β-keto-reductase 3α androstanediol* 3β androstanediol

DHT Precursor in women ASD and DHEAS 1/10 th blood level of testosterone Tissue differences Male internal v. external genitalia Hair follicle/pilosebaceous unit 5α-reductase in skin Muscle, brain, liver, breast

Hair Growth

How many hairs? All follicles present by 22 wks gestation Concentration per unit facial skin Not differ between sexes Differs between racial groups Also 5α-reductase activity Asynchronous

Hair & puberty Vellus hair DHT Terminal hair Duration of exposure and intrinsic potential Eyebrow, eyelashes, scalp

Definitions Hirsutism Excessive body & facial hair in androgen dependent sites Defeminization Weakening or loss of feminine characteristics Virilization Acquisition of mature male somitic characteristics

PCOS and hyperandrogenism Hypothalamus & Pituitary Peripheral fat Adrenals Ovaries

Insulin resistance Archard and Thiers 1921 Acanthosis nigricans Several mechanisms Peripheral target tissue resistance Decreased hepatic clearance Increased pancreatic sensitivity

Peripheral resistance Decreased insulin receptor numbers Decreased insulin binding Postreceptor failure

IR & Co-morbidities Insulin directly related to HTN (late) triglycerides and HDL (early) CAD!!! Increased production of plasminogen inhibitor type-1 Impaired fibrinolysis vascular tissue changes

Hormone assays DHEAS, ASD Not significantly protein bound Routine immunoassay DHEAS Adrenal disease Total testosterone Bound and unbound No direct correlation with level of hirsutism Concentration SHBG

SHBG Produced in liver Increased by estrogens and thyroid hormone Excess androgen Decreases SHBG Percent free/active T elevated Increased metabolic clearance of T

DHT 3α androstanediol glucuronide Peripheral metabolite Excellent correlation 5 α reductase activity
