Amenorrhea (and Dysfunctional Uterine Bleeding) Dr. ELHAM GHANBARI JOLFAEI OB&MD Gynecologiest
Amenorrhea: “absence of menses” • “Normal cycle is 28 days • This occurs in 15% of cycles • 98% have cycles between 24-35 days • Average duration 4-6 days (2-8 normal) • Average blood loss per cycle = 30 ml. • > 80 ml. Leads to risk for anemia
PRIMARY AMENORRHEA • Patient has never menstruated • No period by age 14 with no secondary sexual characteristics • No period by age 16 regardless of secondary sexual characteristics
SECONDARY AMENORRHEA • Previously established cycles cease
ALWAYS RULE OUT PREGNANCY Then evaluate the four parts of the system
REASONS FOR AMENORRHEA • Pregnancy • Menopause • Thyroid/Prolactin Disorders • Anovulation • Outflow obstruction • CNS/hypothalamic dysfunction • Drugs/Stress/Nutrition • Chromosomal/Abnormal Sexual Differentiation
ALWAYS RULE OUT PREGNANCY!!!!!!! No matter WHAT!!!
STEP ONE – will diagnose pregnancy, thyroid disorder, hypoprolactinemia and anovulation • LABS • Beta hcg • TSH • Prolactin • MEDS • Progestin challenge • {If galactorrhea, obtain MRI of pituitary/sella turcica}
STEP TWO – will diagnose outflow tract obstruction • Give estrogen “priming”, followed by progestin • Estrogen x 21 days • Add progesterone for the last 5 days
STEP 3- will determine if lack of estrogen is due to ovarian failure vs. altered CNS/pituitary axis • FSH • (LH)
I. UTERUS – VAGINA – OUTFLOW TRACT • Asherman’s – secondary amenorrhea • Imperforate hymen – primary amenorrhea • Vaginal septum – primary amenorrhea • Agenesis – primary amenorrhea • Testicular feminization – primary amenorrhea
