Which hormones rise at 20 wks gestation?
FSH/LH and glucocorticoids
What is gonadostat?
The hypothalamic-pituitary system regulating gonadotropin release
How are low levels of gonadotropins and sex steroids maintained in prepuberty? (2)
- Gonadostat is sensitive to negative feedback of low estradiol.
- Intrinsic CNS inhibition of GnRH secretion.
What steroids increase from ages 8-11? (3)
DHEA
DHEA-s
Androstenedione
When does onset of puberty occur?
Approx 11 y/o
What is the feedback of estradiol on LH during mid to late puberty?
The positive feedback of estradiol on LH creating ovulation is complete and ovulatory cycles are established
Summary of puberty
HPA is suppressed from 4-10 (2 ways)
From 8-11 androgens increase
Age 11-12 GnRH increases and ovarian follicular development occurs.
In what order are somatic changes?
Thelarche (breast development)
Adrenarche/Pubarche (pubic hair and androgen development)
Increased growth
Menarch
TAPup-ME
Tanner staging of breasts
1 -flat 2 - breast bud 3 - enlargement of bud w/o contour 4 - projection of areola 5 - recession of areola and contour established
Menses occurs how long after puberty?
How long after thelarche?
1 yr
2-3 yrs
Primary amenorrhea
Absence of menarche by 13 y/o w/o secondary sex development OR by 15 w/ secondary sex development.

No period for 6 mo
Polymenorrhea
Frequent periods at <21 days
Menorrhagia
Excessive/prolonged BUT regular periods
Metorrhagia
Irregular episodes of uterine bleeding
menometrorrhagia
Heavy and irregular uterine bleeding
Endometrial polyps
Protrusion of endometrium into endometrial cavity.
Signs: Menorrhagia, spontaneous or post menopausal bleeding.
Usually benign.
Adenomyosis is:
Sx
Extension of endometrial glands into uterine musculature.
Might be asymptomatic.
Severe secondary dysmenorrhea and menorrhagia.
Painful sex
Uterine fibroids
Benign tumors from SM cells of myo.
Rarely malignant.
Mostly asymptomatic, but can have excessive bleeding, pressure, pain, etc
Fixed w/ hysterectomy.
Risks for fibroids
Increasing age in reproductive yrs.
AAs w/ 2-3x increase.
Type 1 malignancy
Type 2 malignancy
Type 1 - endometrial adenocarcinoma (most common)
Type 2 - clear cell and papillary serous
Presentation of uterine malignancy
Postmenopausal bleeding
Irregular bleeding
Risk factors for malignancy
Obesity, smoking, unopposed estrogen.
Indications for in office bx
Abn uterine bleeding in postmenopausal women
Intramenstrual bleeding in women 45 to menopause.
<45 y/o w/ unopposed estrogen
TTM of nonstructural causes of AUB
Normalize PGs w/ NSAIDs Antifibrinolytic therapy (tranexamic acid) Coordinate endometrial sloughing (MPA and COC) Endometrial suppression (progestin, COC)
Diagnostic D and C
Performed for irregular menstruual bleeding of postmenopausal women to r/o cancers
Therapeauic D and C
Performed for endometrial structural abnormalities (polyps, fibroids, etc)
