12.43
15
2-3 years after breast budding
***Primary amenorrhea (2)
No menarche nor secondary sexual characteristics by 13
OR

TAG Me
Stages of normal development
- Thelarche
- Adrenarche
- Growth peak
- Menarche
Tanner stages - breasts
1 = prepuberty (flat) 2 = primary bud, areola grows 3 = further enlargement 4 = secondary mound (areola) 5 = mature, areola recession
Tanner stages - pubic hair
1 = none 2 = sparse along labia 3 = darker, coarser 4 = more, not on thighs 5 = medial thighs (triangle)
Heterosexual vs. isosexual precocious puberty
Heterosexual = opposite sex (virulization, CAD, etc.) Isosexual = appropriate sex
Congenital adrenal hyperplasia
21-hydroxylase deficiency –> excessive androgen production –> virulization/masculinization
True isosexual vs. Pseudoisosexual
True = early onset of normal axis
Pseudo = early estrogens outside of axis (tumor, etc)
Diagnosing true isosexual precocious puberty
Treatment?
Administer exogenous GnRH, see rise in LH
Leuprolide (GnRH agonist)
10% of true isosexual precocious puberty are caused by a _____
Diagnosing?
CNS disorder
MRI of head
Most common effect of untreated precocious puberty
Short stature (under 5 feet)
Precocious puberty, cystic bone lesions, cafe au lait spots, hypercortisolism
McCune-Albright syndrome (polyostic fibrous dysplasia)
Precocious puberty, high estrogen level, GI polyps, hyperpigmentation in and around mouth
Peutz-Jeghers syndrome (estrogen-secreting sex cord tumor)
When is puberty considered delayed? (3 options)
No secondary sexual characteristics by 13
No menarche by 15-16
No menarche after 5 years from thelarche
Kind of Hypergonadotropic Hypogonadism
Gonadal dysgenesis (Turner syndrome)
Kinds of Hypogonadotropic hypogonadism (6)
- Physiologic delay

- Pituitary tumors/disorders
- Hyperprolactinemia
- Drug use
Anatomic causes of delayed puberty (3)
- Mullerian agenesis
- Imperforate hymen
- Transverse vaginal septum
Secondary amenorrhea - definition
Prior menses, now none for 6 months or more
Kallmann syndrome
Type of hypogonadism
KAL gene (X chromosome) – prevents GnRH neurons into hypothalamus – Primary amenorrhea + anosmia/hyposmia
Hypogonadotropic
Webbed neck, flat shield chest, coarctation of aorta, rudimentary streaked ovaries, no sexual development
Turner syndrome (hypergonadotropic hypogonadism)
Androgen insensitivity syndrome – what is it?
Patient genotype?
Phenotype? (findings)
Androgen receptor defect (high testosterone level)
46 XY
Undescended testes, no uterus, female external genitalia, little pubic hair
Primary amenorrhea, normal breast development, low testosterone, 46XX, vaginal obstruction, no cervix or uterus, normal fallopian tubes
Cause?
Mullerian agenesis (Meyer-Rokitansky-Kuster-Hauser syndrome)
Failure of mullerian ducts to fuse distally and create upper genital tract
Primary amenorrhea, normal breast development, normal uterus, monthly dysmenorrhea, no vaginal bleeding, vaginal bulge and midline cystic mass
Tx?
Imperforate hymen
Hymenectomy
Primary amenorrhea, normal breast development, normal uterus, monthly dysmenorrhea, no vaginal bleeding. No vaginal bulge.
Transverse vaginal septum
MOST COMMON cause of secondary menstrual irregularity
PREGNANCY
Endocrine causes of secondary amenorrhea (6)
- Poorly-controlled DM
- PCOS
- Cushing’s
- Thyroid dysfunction
- Premature ovarian failure
- Late-onset CAH
Acquired causes of secondary amenorrhea (4)
- Stress
- Meds
- Exercise
- Eating disorders
Tumor causes of secondary amenorrhea (3)
- Ovarian
- Adrenal
- Prolactinoma
Secondary amenorrhea - labs?
- Urine hCG (pregnancy)
- TSH (hypothyroid)
- Prolactin (prolactinoma (> 100), ectopic causes (under 100))
- FSH
Secondary amenorrhea. TSH and prolactin are normal. Now do what?
Result meanings?
Progesterone challenge test
- Bleeding = PCOS, other
- No bleeding = low estrogen or outflow abnormality
Secondary amenorrhea. TSH and prolactin are normal. Progesterone challenge test is negative. Now do what?
Result meanings?
Estrogen/progesterone challenge test
- No bleeding = outflow obstruction
- Bleeding = HP axis or ovarian issue
Secondary amenorrhea. TSH and prolactin are normal. PCT is negative, E/P challenge test is positive. Now what?
Result meanings?
FSH and LH levels
- High = ovarian issue
- Normal/low = H-P axis issue
How to distinguish hypothalamic from pituitary cause of secondary amenorrhea?
MRI of head – no mass = hypothalamic issue
Mass = pituitary issue
Secondary amenorrhea, TSH and prolactin are normal, PCT and E/PCT are negative…
Causes of secondary outflow tract obstruction (2)
Asherman syndrome - scarring in uterus from previous procedure
Cervical stenosis
Secondary amenorrhea. TSH and prolactin are normal. PCT is positive…diagnoses?
- Nonclassic CAH
- Cushing’s
- Adrenal androgen tumor
- PCOS
- Sertoli-Leydig tumor
- Exogenous androgens
Diagnosing PCOS - criteria
2 of 3:
- Chronic anovulation
- LH:FSH = 2:1
- Cysts beneath ovary cortex
How to treat PCOS? (5)
- Weight loss
- OCPs (reduces FSH/LH, and increases sex hormone binding globulins, thus decreasing testosterone level)
