PCOS: An Ancient Disorder
Hippocrates (460-377 BC):
“But those women whose menstruation is less than 3
days or is meager, are robust, with a healthy
complexion and a masculine appearance; yet they are
not concerned about rearing children nor do they
become pregnant.”
Azziz R et al: Polycystic Ovary Syndrome: an ancient disorder? Fertil Steril. 95, No 5, 1544-8(2011)
PCOS DIAGNOSIS
1st described in 1935 by Stein and Leventhal
First thought to be an anatomic disorder
Multiple attempts to refine the definition of
PCOS
Consensus statements change over time
Stein IF, Leventhal ML: Amenorrhea associated with bilateral polycystic ovaries. Am. J. Obstet. Gynecol. 29, 181-191 (1935).
The Rotterdam ESHRE/ASRM Sponsored PCOS Consensus Workshop Group, 2004
PCOS
PCOS: a syndrome not a disease
List of potential signs or symptoms and no
one single test can make the diagnosis
Creates confusion. Many with PCOS are not
diagnosed and many more do not
understand their diagnosis
Only in last decade has PCOS been gaining
recognition
PCOS DIAGNOSIS
Androgen Excess and PCOS Meeting(2006)
Must meet all 3 criteria:
1. Hyperandrogenism (hirsuitism, acne or
hyperandrogenemia)
2. Ovarian dysfunction (oligoovulation, anovulation
and/or polycystic ovaries)
3. Exclusion of other androgen excess disorders (CAH ,
Androgen secreting tumors)
NIH 2012 Proposal
Androgen excess + polycystic ovarian
morphology
Ovarian dysfunction + polycystic
ovarian morphology
Androgen excess+ ovarian dysfunction
+ polycystic ovarian morphology
NIH 2012 Conclusions
Complex metabolic, hypothalamic,
pituitary, ovarian and adrenal
interaction
Need better definition and recognition
of different phenotypes
Need better androgen assay
NIH 2012 Conclusions
Need lab ranges that are ethnic and age
specific
Pregnancy related complications are
greater in more classic PCOS as
opposed to non hyperandrogenic
profile
Suggest renaming this syndrome
PCOS
• Most common endocrine disorder in females
•
•
•
•
(6-15%)
Subfertile not infertile
Heterogeneous condition: different
phenotypes
Associated with extremes in body habitus
BMI extremes affect health status, fertility
impairment, ART success and pregnancy
outcome
Stein-Leventhal Description
Stein and Leventhal:
enlarged ovaries
smooth surface - not the
typical rugae that are
present in normal
women
multiple small cysts that
were identified to be
follicles
histologic hypertrophy
of the theca
Boston IVF
PCO-Like Ovaries
“String of pearls sign”
Ovulatory Dysfunction
Greater LH pulse frequency and amplitude
Causes excess androgen production
FSH level too low to mature the follicles
FSH suppressed by mid follicular E2 levels
that cause negative feedback
Baseline E2 levels tend to be higher
AMH levels are elevated
Hyperandrogenism
Virilization
Decreased breast size
Clitoral enlargement-rare
Male pattern baldness
Voice can deepen
Acne
Acanthosis nigrans associated with >
metabolic risk
Hyperandrogenism
Hirsuitism is best marker for
hyperandrogensim: 70%-90 of PCOS
women have this (acne and alopecia less
common)
Hyperandrogenism and
oligomenorrhea- > metabolic risk
Adams J, Polson DW, Franks S. Prevalence of PCO in nornal woemn with anovulation and idiopathic hirsuitism. BrMed j. 1986;293(65430:355-9
Pathophysiology of PCOS
Thecal cells produce increased androgens
Results in elevated LH and a relative FSH
deficiency favoring androgen synthesis
Increased androgens result in many small
follicles
May result in anovulation, hirsuitism,
typical PCOS ovarian morphology
A VICIOUS CYCLE
Increased body weight results in increased
IR and compensatory hyperinsulinemia
Insulin stimulates ovarian synthesis of
testosterone
Insulin inhibits SHBG in the liver resulting
in increased free testosterone
High testosterone causes more abdominal
fat and increased IR
IR causes hyperandrogenism
Etiology of PCOS
Strong evidence of genetic link supported by familial
incidence and twin studies
Prenatal exposure to androgens is associated with
PCOS
Most likely poly-genetic disorder
Insulin resistance (IR) is a socioecologic adaptation
to changes in diet and lifestyle. IR favors PCOS
Obesity varies between ethnic groups of PCOS
women
Etiology of PCOS
Mothers
and sisters of women with PCOS
are more likely to acquire PCOS after
menarche
Female
children of women with PCOS
more likely to develop insulin resistance
after puberty
PCOS
is inherited equally from father
and mother

PCOS and Body Image
Hyperandrogenism is exacerbated by
hyperinsulinemia and associated with:
-Acanthosis nigricans
-Acrochordons (skin tags)
-Purple-tip abdominal striae
-Centripetal apple obesity
Obviously these changes
affect body image!!!
PCOS
Hirsuitism/Acanthosis Nigricans
Ferriman-Gallwey score
Stigmata of hyperinsulinemia:
Acanthosis nigricans (axillary)
Who Is At Highest Risk?
Central obesity (apple or visceral adiposity)
Genetic and predisposes an individual to IR,
dyslipidemia and hypertension
Androgens inhibit hepatic and peripheral insulin
effect
PCOS associated with truncal fat
Elevated waist circumference at highest risk for
metabolic syndrome within several years
Obesity
PCOS and IR
Not included in diagnostic criteria
Cells stop responding well to insulin
Body perceives elevated glucose
Increases insulin. Cells bombarded, but not receptive
Abdominal fat aggravates IR and worsens the sxs of
PCOS.
Goal: sensitize cells or to find ways to
increase the insulin effect
Abnormal Glucose Metabolism
64% of PCOS pts have IR
40%of PCOS pts have impaired GTT
10% develop Type 2 diabetes by their 4th decade
Prevalence of obesity among women with PCOS in
the US has increased to 74% in 2002, paralleling
the increase in obesity in the general population
PCOS and Mood Disorders
Increased depression and anxiety
Mood disorders, social phobias and sleep disorders
increased
Psychological issues should be considered in all PCOS
pts
Unclear if due to disorder or the comorbidities
Appropriate counseling should be offered

LH
FSH/LH ratio (40% have normal ratio)
E2; AMH
Testosterone
Androstenedione
Hgb A1C 5.6-6.4=“at risk”
Insulin, Glucose tests
Differential includes:
DHEA-S, 17OH-P,TSH,Prolactin
24 hr urine cortisol
*Provera challenge may help with diagnosis
*Lipid panel to assess CVD risk (triglycerides too)
Importance of Education
Patients want to understand their condition
Can empower them to make radical change
if they understand why and the high stakes
They need our help!!
Explaining PCOS to your patient
Insulin: hormone secreted by the pancreas in
response to the rise in glucose (sugar) after
the digestion of carbohydrates – e.g. grains,
fruits, milk, yogurt, sweets, and starchy
vegetables like potatoes, sweet potatoes,
squash, yams, corn, peas and legumes.
Once released, insulin "unlocks" muscle, fat
and liver cells so that glucose can pass into
the cells either used as fuel or stored as an
energy reserve
Explaining PCOS to your patient
With IR, cells are not as sensitive to insulin,
stimulating the pancreas to secrete more insulin in
an attempt to keep blood sugars normal. (This
"overdrive" may over time, exhaust the pancreas and
lead to diabetes)
The excess circulating insulin is thought to trigger
the hormonal changes seen in PCOS (ovaries are not
insulin insensitive!)
Patients need to know
Obesity negatively impacts ART success
rates:
Difficulty with oocyte retrieval
Less oocytes with morbidly obese
Decreased oocyte and embryo quality
Decreased uterine receptivity
More difficulty with ETs
Decreased IR and PR (? not with DE)
Pregnancy related risks and general health risks
Martinuzzi K et al. J assist Reprod Genet. 2008;25(5):169
BIVF Study of 4,609 women undergoing 1st
IVF cycle
68% lower chance for live birth for OW and
obese
BMI > 25: 42% lower IR; 57% decline in CPR
CPR dropped slightly for underweight women
but declined significantly for OW women
“A modest amount of weight loss might
improve IVF success rates.”
Jones ,S. 2011 ASRM Orlando
SART data analysis of BMI and cycle outcomes
(2011)
Higher cancellation w/ BMI >30
Reduced clinical pregnancy rate with autologous
cycles w/ BMI > 30
Worse prognosis with increasing BMI
Reduced live birth rate with autologous cycles w/
BMI >25
Higher risk of SAB/IUFD with increasing BMI
Variable with thaw and DE cycles
Luke, Increasing Obesity and ART Outcomes. Fertil Stertil 2011
WHAT HAS CHANGED?
Our foods and lifestyles have drastically changed:
-toxic food environment
-collective reduced energy expenditure (80% of jobs
are sedentary)
-Lack of public awareness/will to push for the
necessary policy changes
Fast Food and Advertising
High Fructose Corn Syrup(HFCS)
Corn subsidies support millions of acres of corn
More than half of US field corn go into animal feed
which affects quality of our meat and poultry
USDA (2003) estimates the average American eats
79 pounds of corn sweetener per year
Added to: boxed cereal, ketchup, fruit juice, soda
and soft drinks, margarine, chips
Resulting in approximately 500
more calories a day
1 Lifesaver per day= 1.5 lbs per year
Fat Monkeys
Monkeys eat when they are bored and not even
hungry
Unlike humans who underreport their intake, rhesus
monkeys can be closely monitored
When fed a poor diet they become 3 times their
normal weight
High fat diets alone have not tended to make
monkeys obese, but a high fructose corn sweetened
punch ignites weight gain and IR
Obesity
Is it genetic?
Genes affect both energy intake and energy
expenditure
Metabolic rate of people matched for body weight, sex and age
may differ by up to 500 calories/day
Some people burn more calories even when not trying to
exercise
Twin studies show hereditary component
Genetic differences explain radically different weight
gains and losses between individuals
Twin Studies
6 days a week they ate 1000 extra cals per day
Weight gain was between 10-29 pounds
These studies suggest a biologic determinism that makes
a person susceptible to weight gain or loss and how much
32 distinct genetic variations assoc with obesity. Those
carrying a common variant known as FTO faced
increased risk: 30 % if 1 copy and 60% if 2 copies. Those
with the gene tend to eat more foods with higher fat and
calories
De Bouchard and Tremblay
Oct 2010 J of N G
Nature and Nurture
Genetics loads the gun, environment
pulls the trigger
One’s own prenatal environment may
play a role (epigenetics)
Leptin and Gherlin
Leptin and Gherlin
Women with PCOS may have abnormal gherlin and
leptin levels
Gherlin is the gastric and pancreatic hormone that
makes us feel hungry. (Also produced by
hypothalamus)
Leptin is the hormone made in adipose tissue that
makes us feel full
Women with PCOS maintain higher gherlin levels
after a meal and report difficulty feeling full
Anti obesity vaccine targets gherlin
Importance of Diet & Exercise
Women with PCOS who lose weight are
more likely to have:
Decreased androgens
Restored ovulation
Higher pregnancy rates
Lower rates of hypertension and metabolic
syndrome
Managing Glucose and Insulin levels
Less insulin
Lowers
androgens
Less hirsutism,
acne,alopecia,
weight loss
Setting Measurable and Realistic Goals
5-10% weight loss in women with PCOS
can have a positive effect on insulin
resistance, impaired glucose tolerance,
metabolic syndrome and fertility
The Challenge
Difficult to gain or lose weight at
the extreme ends
More challenging to maintain
weight loss (no FDA approval for
this class of medications)
The Power of Food
We celebrate with food; we take care of our sorrow
with food; and we all approach food differently. It
partly has to do with the family we grew up in: was
food a reward or was food withheld as a
punishment?
We should eat to live, not live to eat
Obstacles to Weight Loss
Never raising the issue with patient
Never taking the time to explain the detrimental
effects of elevated BMI and reproductive outcome
Telling your patient: Lose weight and then come
back to see me
Using insensitive words, tone and actions that shame
the patient so they never return
Obese patients are more likely to delay and cancel
medical appointments
Obstacles to Weight Loss
Obesity doesn’t carry the same cultural stigma it
once did.
As Americans increase in size, there is less urgency
to lose weight because on average, others are heavier
too.
How to Motivate?
SUGGESTION:
Food Journaling
In fact, one study on people
trying to lose weight showed
that, along with attending
weekly classes on nutrition and
portion control, those who
kept a food diary six days per
week lost twice as much as
those who logged only once per
week or less.
Hollis, J. American Journal of Preventive
Medicine, August 2008; vol 35.
Balance Your Fats
Decrease Saturated Fat
Include Healthy Mono and Polyunsaturated
fats- olive & canola oil, avocados, walnuts, flax,
sunflower, sesame, almonds, peanuts, fish
REMOVE ALL Trans Fat- These are
manmade chemical fats that negatively affect
ovulation and increase cholesterol and
inflammation.
Focus on Fiber
Opt for at least 3 daily servings of unrefined
grains (such as whole grain breads and
cereals, brown rice and whole wheat pasta).
Because fiber is not digestible, it slows the
digestion process, which then slows the
release of sugar into the blood. High-fiber
diets are also strongly linked to weight loss.
Exercise
Metabolism slows down when you don’t
move for long periods of time
Little steps important: take the stairs
Try to MOVE!
Get a workout buddy or join an online
community like: www.sparkpeople.com
Exercise
Decreases stress, lowers blood pressure and
cholesterol
Increases muscle mass (which increases glucose
storage). Muscle burns 12 x more calories than fat.
Increases insulin sensitivity even in the absence of
weight loss
Probably has the greatest ability to improve insulin
sensitivity of all of the lifestyle modifications
Which Diet is Best?
Most popular diets result in similar weight loss
over 1 year
Insulin, cholesterol and C-RP levels are similar
Main problem: 60-86% of weight will be regained
within 3 years
Recent NEJM study: Mediterranean diet is best
(good fat vs bad fat) re: CVD risks.
Dansinger ML et al. JAMA.2005;293(1):43
Estruch R, Ros E, Salas-Salvadó J, et al. Primary prevention of cardiovascular disease with a Mediterranean diet. N Engl J Med 2013; DOI:10.1056/NEJMoa200303. Available at: http://www.nejm.org/.
.
Changing the Attitudes of Staff
Admitting negative associations is
necessary for some care providers
Admitting difficulty in raising the issue
Staff may have weight issues that need
to be addressed simultaneously
Suggested Positive Changes
Create a compassionate environment
Provide a mix of support and education
Private weigh-ins
Proper equipment for BP checks
Consider starting an in house weight loss program or
refer to a reputable program or person
Educational Tools and Resources
Myths, Presumptions vs Facts
Myth: Patients should set realistic goals for
weight loss. Otherwise they might become
frustrated and not lose as much.
Fact: Studies have shown that patients who
set more ambitious goals are likely to lose
more weight
KCasazza et al NEJM 2013; 368:446-454 January 2013
Setting Goals
Recognizing that patients respond to different
approaches to weight loss
Individual counseling
Groups
Multidisciplinary approach
Involving family members
Approach should be similar to
nicotine and alcohol addictions or
lifelong conditions like hypertension
Helpful Interventions
Recent research supports the efficacy of a
combined individual and group intervention
RMA-CT has had good patient results by
adding different components to the group
sessions
Certain sessions are mandatory and billable
Appel et al, NEJM 2011
Weight Loss at BIVF
BIVF Weight Loss Program
One session will be held at a local grocery store,
where the nutritionist will lead participants to the
healthiest food sections, and teach them how to read
food labels
For the last session, participants will each bring in a
healthful dish to share
During each session, the nutritionist will be teaching
participants how to incorporate life-long healthier
eating habits, rather than dieting tips
Possible Motivators
You can try:
medical facts demonstrating the health risks
medical facts demonstrating the obstetrical risks
increasing one’s chance for pregnancy sooner
desire to be a good role model for child
desire to prevent childhood obesity
acknowledge how hard it is to lose weight and even harder to
maintain weight loss
similar approach to treating other addictions
Lifestyle changes
Diet and Exercise
Medications:
Metformin or
antiobesity
Severe; Bariatric
surgery
Pregnancy
Anovulation
Ovulation
Induction:
clomiphene or
Letrozole
Clomiphene
resistant; add
metformin or try
Letrozole
ART: Aim for
Singleton and no
OHSS
Anti- Obesity Drugs
Exanatide once weekly (Byetta)and Liraglutide once
daily(Victoza)
Glucagon-like peptide-1 receptor (GLP-1R) agonists led
to greater weight loss than other diabetes treatments and
should be considered for obese diabetic patients
BMJ 2012;344:d7771
Anti-Obesity Drugs
FDA Approves Weight management drug Qsymia
July 2012
Indications: BMI> 30 or BMI >27 with HTN, T2D or
hyperlipidemia
Combo drug: phentermine and topiramate ER
Phentermine is approved for OW pts who exercixe
and diet
Topiramate is an anti seizure and anti migraine drug
Encourage a Singleton Pregnancy
SERM: selective estrogen receptor modulator
(Clomiphene Citrate)
Clomiphene Citrate and Metformin
Aromatase Inhibitor (Letrozole)
IVF with SET (avoid OHSS)
BUT WEIGHT LOSS FIRST!
Letrozole
Off label status
Mechanism of action and dosing
Advantages over Clomiphene Citrate
Should be first-line or at least used
more often for patient benefit
Aromatase Inhibitors
alternative to clomiphene citrate
No antiestrogenic peripheral side effects
No negative effect on endometrial lining
No negative effect on cervical mucus
Short half life – fast clearance from body
Used similarly to Clomiphene Citrate
Letrozole: 2.5 mg tablets 1-3 pills x 5 days
Used in some centers with fertility preservation patients
who may benefit from decreasing peripheral estrogen
levels during stimulation for certain types of cancers
Insulin Sensitizers
Metformin is a biguanide that inhibits the
production of hepatic glucose which decreases insulin
secretion, enhancing insulin sensitivity in peripheral
tissues
The effect of metformin on weight
and fat distribution in PCOS pts
is unclear. Some studies demonstrate
weight loss and reduction in waste
circumference while others have not
Palomba et al.Endocr. Rev. 30(1), 1-50 (2009).
Insulin Sensitizers
Metformin:
No serum insulin level agreed upon to initiate tx
Can decrease Type 2 Diabetes risk
Can improve ovulation
No clear effect on weight or hirsuitism
Not as effective as ovulation induction agents for
infertility tx
Remember, weight loss increases insulin sensitivity
without side effects
5-10% weight loss improves hirsuitism and anovulation
Metformin
Decreased hepatic production of glucose
Increased glucose uptake
Dose- 500mg up to 2 gm or 500/750mg XR
Nausea, diarrhea, bloating
Weight loss or no change
Metformin
Not recommended as first line therapy
Not a panacea even with “classic PCOS’
Reduces hirsuitism but not as well as other methods
No benefit on lipids
Appropriate first line for T2D
Metformin
Should be offered to pts with IGT who do not respond to
diet and exercise advise
No evidence for improved LBR or decreased pregnancy
complications with use of metformin before or during
pregnancy
Improves ovulation rates in CC resistant pts
No support for universal use in all PCOS pts
Best for those with IR, can be lean or obese
Fertil and Steril Vol 97 No 1 January 2012
Summary: Tx Options for PCOS
Diet and exercise
Clomiphene citrate: more effective than metformin
for the induction of ovulation and pregnancy.
Clomiphene-resistant patients with PCOS,
metformin in combination with clomiphene
increases ovulation or Aromastase Inhibitor
Antiobesity drugs may potentiate the effect of diet
and exercise, resulting in weight loss
In patients with severe obesity, bariatric surgery
appears to be the most effective way to lose weight
and to improve fertility.

FUTURE
It is of great importance to develop strategies for the
prevention of overweight and obesity in order to
improve reproductive and metabolic health
The most important challenge is to develop
programs favoring sustained lifestyle modification
Policies must change to curb the obesity epidemic!!
PREVENTION WILL BE
THE KEY!
