Learning Objectives
By the end of this presentation, you will
be able to:
1. List the red flags of oligomenorrhea
and hirsutism
2. Discuss appropriate treatment options
for oligomenorrhea and hirsutism
Hirsutism
Martin KA et al. JCEM 2008;93:1105-1120.
Hirsutism
• Excessive hair growth in women in typically
androgenic areas (terminal hairs)
• 5-10% of women
• Increased androgens or increased sensitivity to
androgens
• Ferriman-Gallway score (FGS)
• FGS > 8 in Caucasion women = abnormal
• May be higher/lower in other ethnicities (Thai
>3)
Ferriman-Galway score
Non-midline hair less androgen-dependent. Best discriminator is
combination of upper lip, moustache, lower abdomen and thighs
Causes of Hirsutism
• Polycystic ovarian syndrome (60%)
• Idiopathic (38%)
• Other (2-3%)
– Drugs (androgens)
– Congenital adrenal hyperplasia (non-classical)
– Ovarian tumours
– Hyperthecosis of ovaries
– Adrenal tumours
– Severe insulin resistance syndromes
PCOS
• National Institutes of Health
– Oligo-ovulation
– Androgen excess (clinical or biochem)
– Exclude other diseases
Clinical Evaluation:
RED FLAGS
• Rule out the BAD THINGS = ovarian / adrenal tumor
• Early onset
• Rapid progression
• Virilization
– Voice change
– Change in body build
– Clitoromegaly
– Frontal balding
Clinical Evaluation: HISTORY
• Hirsutism details:
– Onset, progression, location, severity
• Associated features:
– alopecia, acne, virilization, Cushingoid
• Menstrual history
• Weight history
• Medication history
• Family history
– diabetes, PCOS, hirsutism
• Ethnicity
Clinical Evaluation: PHYSICAL
Vellous
Terminal
Acanthosis nigricans
Ferriman-Galway score
Non-midline hair less androgen-dependent. Best discriminator is
combination of upper lip, moustache, lower abdomen and thighs
Clinical Evaluation: PHYSICAL
• Weight
• Insulin resistance
– acanthosis nigricans, skin tags
• Virilization
– acne, oily skin, alopecia, voice, hair, muscle bulk,
clitoromegaly
• True hirsutism?
– Vellous vs Terminal
Clinical Evaluation: LABS
• Not ALL women require lab testing
• Total testosterone (normal < 2.8 nmol/L) (M > 11)
– Very high androgen-secreting tumour or ovarian
hyperthecosis?
– Normal to mild elevation PCOS or idiopathic?
• DHEA-S
– If very high … consider adrenal tumour
• Select cases:
– FSH (estrogen deficiency states)
– LH (may be high in PCOS)
– Prolactin
– 17-OH progesterone
Clinical Evaluation: IMAGING
• Only if you suspect an ovarian or
adrenal tumour
Martin KA et al. JCEM 2008;93:1105-1120.
Hirsutism - Treatment
• Discussion of “patient-imporant hirsutism”, goals, realistic expectations
• Local strategies may be perfectly adequate
– Waxing, threading, bleaching
– Laser and electrolysis +/- eflornithine cream (Vaniqa)
• Systemic treatment- only effective while taking
• Combining anti-androgens with local methods gives most effective control
Systemic Therapy
Oral Contraceptive Lowest to highest Androgen action (American Hair Loss Association):
• eliminates ovarian
androgen production
• raises SHBG which
reduces free testosterone
• androgenic progestin
• Yasmin (Drospirenone)
• Yaz (Drospirenone)
• Desogen (desogestrol)
• Ortho-Cept (desigestrol)
• Ortho-Cyclen (norgestimate)
• Ortho Tri-Cyclen
• Micronor (norethisterone)
• Nor-Q D
• Ovcon-35 (Norethisterone)
• Brevicon/Modicon
• Ortho Norvum 7/7/7
• Ortho Novum 10-11
• Tri-Norinyl
• Norinyl and Ortho 1/35
• Demulen 1/35 (ethynodiol diacetate)
• Triphasil/Tri-Levien (levonorgestrel)
• Nordette
• Lo/Ovral
• Ovrette
• Ovral
• Loestrin 1/20 (Norethidrone)
• Loestrin 1.5/30
Systemic Therapy
• ANTI-ANDROGEN
– Spironolactone 100-200 mg/d (divided BID)
– Cyproterone acetate 50-100 mg/d on menstrual cycle day 5-15, dose reduction after effect seen
– Finasteride (5a reductase inhibitor) 2.5-5 mg/day
• Only as ADD-ON to OCP
• Give at least SIX MONTHS before re-evaluating
Martin KA et al. JCEM 2008;93:1105-1120.
Summary
• Hirsutism vs Hypertrichosis
• Look for red flags
• May not require labs
• Androgens can be helpful
• Local, systemic, combination therapy
• Takes time to take effect
• Manage expectations
Oligomenorrhea /
Secondary amenorrhea
Learning Objectives
By the end of this presentation, you will
be able to:
1. Recite the common causes
2. Describe appropriate investigations
3. Utilize common treatments
Oligomenorrhea /
Secondary Amenorrhea
• OLIGOMENORRHEA:
– >35 day cycles
• SECONDARY AMENORRHEA
– Absence of menses for >3 cycles or 6 months
in women who previously had menses
Causes (categories)
• Pregnancy most common cause (20
amenorrhea)
• Ovarian — 40 %
• Hypothalamic — 35 %
• Pituitary — 19 %
• Uterine — 5 %
• PCOS (Polycystic ovarian syndrome) • Ovulatory dysfunction
• Clinical (acne, hirsutism, alopecia) or biochemical evidence of hyperandrogenism
• Exclusion of other diagnoses
• Premature ovarian failure (< 40y)
• Turner syndrome, Fragile X
• Autoimmune
• Radiation / chemo
• Infection
Differential Diagnosis – Ovary
Differential Diagnosis –
Hypothalamus
• Functional
– Stress, exercise, anorexia, chronic illness
• Tumours
• Infiltrative diseases
– Histiocytosis, sarcoid, hemochromatosis
• Brain injuries
• Genetic syndromes
– Usually primary amenorrhea
Differential Diagnosis –
Pituitary
• Prolactinoma – 90%
• Hypopituitarism• Adenoma, tumour
• Infiltrative, inflammation
• Radiation
• Postop
• Apoplexy/Infarction
• Sheehan’s syndrome
• Empty sella
Differential Diagnosis –Uterine
• Usually primary amenorrhea
• Asherman’s syndrome is the only uterine
cause of secondary amenorrhea
– Endometrial scarring – D&C, post-partum
hemorrhage, infection
– No uterine stripe on pelvic ultrasound
– No withdrawal bleed post estrogen and
progestin
General Approach
• Rule out pregnancy
• Rule out Asherman’s syndrome: • Previous instrumentation, D&C, uterine hemorrhage,
infection etc
• Once above excluded then consider • Hypothalamus
• Pituitary
• Ovary
History
• Hypothalamic – Functional, space-
occupying lesion (SOL)
• Pituitary – Galactorrhea, SOL, hormone
excess, hypopituitarism
• Ovarian
– PCOS – androgen excess
– POF – low estrogen, hot flashes,dryness
• Meds, PMH, etc
Physical Examination
• General
• BMI (high – PCOS, low – Functional, illness)
• Cushingoid, acromegalic, cachectic
• Visual fields
• Thyroid
• Galactorrhea
• Skin
• hirsutism, acne, striae, acanthosis nigricans, vitiligo, bruising, etc.
• Routine exam
Investigations
• Beta-HCG
• Pituitary –> LH, FSH, Prolactin
• Ovary –> Estradiol, DHEAS, Testosterone
• Thyroid –> TSH
Investigations
• Progestin withdrawal test
• Provera 10 mg/d x 10 days
• Withdrawal should induce a bleed IF there
is a lining
• Withdrawal bleed = adequate estrogen
• Pelvic imaging as needed
Narrowing it down…
Case A• 18 year old female
• Menarche at 13 yrs. Menses stopped 2y ago
• No hyperandrogenism symptoms
• No diet restriction but heavy exercise
• Low/normal LH & FSH, FSH>LH, low E2
• No withdrawal bleed post progestin
• Dx: Functional Hypothalamic Amenorrhea
(hypogonadotropic hypogonadism)
• Rx: increase calories, decrease exercise, Ca /
Vit D, +/- MRI head
Case B• 36F G2P2
• Menarche at 12.5y
• Regular menses monthly until 6 months ago
when suddenly stopped
• Some breast tenderness, no galactorrhea
• Low LH, FSH, E2
• High Prolactin, normal TSH
• Confirm, r/o secondary causes
• Imaging – MRI, BMD, visual field testing
• Tx: Dopamine agonist
Case C
• 38y F G0P0
• PMH: SLE on Imuran
• Secondary amenorrhea x 9 months
• Hot flashes
• High FSH, low E2
• No withdrawal bleed with progestin
• Hypergonadotropic hypogonadism
• Investigations – karyotype, adrenal
antibodies, BMD
• Tx – HRT / OCP, Ca/Vit D
Case D• 20F, G0P0
• Severe hirsutism over last 6 months
• Voice deepening, body build change
• Very high testosterone DHEAS
• Very high DHEAS and androstenedione
• Suspect virilizing tumour
• Imaging
• Refer for surgery
Take Home Points
• Pregnancy is most common cause
– Beta-hCG in all
• History/Physical usually diagnostic
• Organize approach anatomically
• Think of feedback loops when analyzing
lab results
• Refer appropriately
