- secondary sexual characteristics
- evaluate cyclic menstrual pain
(inperforate hymen)
Amenorrhea: Primary
Etiologues?
5
- Chromosomal abnormality (gonadal dysgenesis, Turner’s syndrome) 50%

- Mullerian agenesis (absence of uterus, cervix and vagina 15%
- Transverse vaginal septum or imperforate hymen 15%
- Other:
- CAH,
- PCOS,
- androgen insensitivity
Amenorrhea: Primary
Hx findings?
9
1, cyclic pelvic pain,
- other stages of puberty,
- headaches,
- virilization,
- galactorrhea,
- medications,
- stressors, weight change
- illness
- FH of delayed puberty
Amenorrhea: Primary
Possible Exam findings?
3
- Tanner Staging (Breast development is a marker for Estrogen = Ovary)
- Pelvic exam to confirm patent hymen and presence of vagina
- Signs of Turner’s (low hairline, web neck, widely spaced nipples with shield chest)
Amenorrhea: Primary
1. Initial Lab?
- Further lab based upon what? 2
- What could these furthers labs be? 5
- Initial imaging? 1
- FSH
- FSH and
- presence or absence of breast development and uterus
- could include
- karyotype,
- testosterone,
- TSH,
- prolactin and
- pregnancy test - Initial imaging: ultrasound to confirm uterus
Amenorrhea: Secondary 1. RULE OUT WHAT? 2. Ovarian causes? 2 3. Hypothalamic causes? 3 (What is decreased in hypothalamic causes?)
- PREGNANCY
- OVARIAN 40%
- PCOS 20%
- Primary Ovarian Insufficiency (PCO) less than 40 yo - HYPOTHALAMIC
-Weight loss and exercise
-Nutritional deficiencies: low body fat; celiac
-Emotional stress or illness
(FUNCTIONAL (decreased GnRH))
Amenorrhea: Secondary
- Nonfunctional hypothalamic causes? 1
- Pituitary causes? 4
- Uterine causes? 2
1. Hypothalamic Infiltrative tumors (rare)
- Pituitary
- Hyperprolactinoma
- Other causes of elevated prolactin
- Injury to pituitary
- Hypothyroidism - Asherman’s syndrome (acquired scarring of cavity)
- Tuberculosis
What are some injuries to the pituitary that would cause secondary amenorrhea?
3
- Sheehan’s syndrome,
- radiation,
- infiltrative disease like hemochromatosis
Amenorrhea: Secondary
Hx questions?
9
- Menstrual hx
- Exercise and eating patterns,
- Medications that may increase prolactin
- Stress
- Post partum hemorrhage
- Radiation to head
- Headaches
- Hot flashes
- Uterine surgeries
Amenorrhea: Secondary
exam? 4
Initial labs? 6
- BMI,
- hirsutism
- galactorrhea
- UTERINE SIZE
- pregnancy test,
- FSH,
- TSH,
- prolactin,
- possibly testosterone and
- DHEA-S
What is dysmenorrhea?
Painful periods
- Describe what primary dysmenorrhea is?
- How does it typically present? 3
- Describe what secondary dysmenorrhea is? Associated with which dz processes? 3
- Primary: No obvious cause, typically
- begins in adolescence as -
- crampy,
- midline lower abdominal pain
- associated with onset of menses - Secondary: Symptoms attributed to specific problem like
- endometriosis,
- adenomyosis or
- fibroids or PID
Dysmenorrhea: Primary
Risk factors?
8
- Age less than 30
- BMI less than 20
- Smoking
- Menarche less than 12
- Irregular/prolonged/heavy menses
- Hx of sexual assault
- Family hx
- Younger age of first child and higher parity lower risk
- Dysmenorrhea: Primary
PP? - Uterine ischemia results in what?
- Prostaglandins released with endometrial sloughing induce contractions
- anaerobic metabolites which stimulates type C pain neurons
Dysmenorrhea: Primary
Presentation?
4
- Pain begins after ovulatory cycles established
- May start 1-2 days before menses; gradually diminishes over 12-72 hours
- Unilateral pain or non-cyclic pain suggests other dx
- Nausea, diarrhea, headache may be present
Dysmenorrhea: Primary
Dx?
4
- No physical exam findings
- No lab abnormalities
- No imaging study findings
- Dx by history and normal exam
Dysmenorrhea: Primary
- General evaluation?
- What things suggest secondary causes? 5
- EVALUATION: Focus on exclusion of secondary dysmenorrhea:
- Onset of symptoms >25
- Nonmidline pain
- Dyspareunia
- Progression of symptoms
- Abnormal uterine bleeding suggest secondary causes
Dysmenorrhea: Primary
Firstline Rx?
4
- Self-care: heating pad, exercise and relaxation techniques
- NSAIDs
- Suppression of menses with contraceptive hormones
- Limited data and small studies report reduced cramps with diet and supplements: low fat-vegetarian diet;3-4 dairy servings/day; vit E 2 days before thru 1st 3days of menses; 1-2 gm fish oil/d; Vit B1 100 mg/d; vit B6 200 mg/d
Dysmenorrhea: Secondary
Causes?
10
- Endometriosis 2. Adenomyosis
- Fibroids 4. Ovarian cysts
- Intrauterine/pelvic adhesions
- Obstructive endometrial polyps
- Obstructive mullerian anomalies
- Cervical stenosis 9. IUD
- Pelvic congestion syndrome
Abnormal Uterine Bleeding (AUB)
Basic labs? 5
- CBC
- Prolactin
- TSH
- Pregnancy test
- Chlamydia testing when indicated
Abnormal Uterine Bleeding: Diff Dx
9
- Polyp
- Adenomyosis
- Leiomyoma
- Malignancy
- Coagulation
- Ovulatory dysfunction
- Endometrial
- Iatrogenic
- Not yet classified
Abnormal Uterine Bleeding: Terms
- Polymenorrhea?
- Menorrhagia?
- Metrorrhagia?
- Oligomenorrhea?

- cycles> 35 days
Abnormal Uterine Bleeding:Coagulation
20 % of women presenting with heavy menstrual bleeding have an underlying bleeding disorder
SUCH AS?
VonWillebrand’s
