Early follicular/proliferative phase
Decreasing E and P Increased GnRH pulse frequency Increased FSH --> follicular growth in ovaries Increased LH pulse frequency Menses from P withdrawal
Mid follicular/proliferative phase
Increased FSH acts on ovarian granulosa cells
Increased E released from follicles
-ve feedback from E –> decreased FSH and LH
Cervical mucus clear, increasing amount, more stringy
Late follicular/proliferative phase
Growing follicles cont to secrete E Increasing E from follicles, esp from dominant follicle Dominant follicle persists Remainder undergo atresia Granulosa cells luteinize --> produce P E builds up endometrium
Estrogen in menstrual cycle
Main hormone in follicular/proliferative phase
Stimulated by FSH
As level increases it acts -vely on FSH
Majority is secreted by dominant follicle
E acts on:
Follicles in ovaries to reduce atresia
Endometrium to induce proliferation
On all target tissues (decreased E receptors)
Progesterone in menstrual cycle
Main hormone in luteal/secretory phase
Stimulated by LH
Increased progesterone acts -vely on LH and is
Secreted by corpus luteum (remnant of dominant follicle)
P acts on:
Endometrium to stop build up, organize glands, prevent degradation
On all target tissues to decrease E and P receptors
Luteal/secretory phase
Fixed 14 days
Ovulation
Early-mid
Late
Ovulation of luteal/secretory phase
Sudden switch from -ve to +ve feedback (E and P cause increased FSH and LH)
E peaks –> LH surge –> ovulation
36h after LH surge, dominant follicle releases oocyte
Corpus luteum forms from dominant follicle remnant nad produces P
Early-mid luteal/secretory phase
Switch back to -ve feedback
Increased P from corpus luteum –> decreases LH and FSH
P stabilizes endomtrium
Late luteal/secretory phase
No fertilized oocyte
Decreased P secondary to CL degeneeration –> menses

Labia becomes thin, atrophic Pruritus, dyspareunia, burning Figure of 8 distribution Most common in postmenopausal women Tx: Ultrapotent topical steroid clobetasol x 2-4wk then taper down, can consider long-term suppression twice a week
Most common malignant vulvar lesion
SCC
Vulvar intraepithelial neoplasia (VIN)
Contain HPV DNA (usually types 16, 18)
White or pigmented plaques on vulva (may only be visible on vulva)
Progression to CA rarely occurs with appropriate management
Tx: local excision, ablative therapy, local immunotherapy (imiquimod)
T1 vulvar lesion
Tumour confined to vulva
No extension to adjacent perineal structures
Tx: Radical local excision
T2 vulvar lesion
Tumour of any size with extension to adjacent perineal structures
Tx: Modified radical vulvectomy
T3 vulvar lesion
Extension to any of: proximal 2/3 of urethra, proximal 2/3 of vagina, bladder mucosa, rectal mucosa or fixed to pelvic bone
Tx: Chemoradiation
Node +ve dz: Adjuvant chemoradiation or radiation therapy
Most common malignant vaginal lesion
SCC
Most common location of vaginal SCC
Upper 1/3 of posterior wall of vagina
Vaginal adenocarcinoma
Most are metastatic from ovary, cervix, endometrium or colon
If primary, most are clear cell adenocarcinomas
Malignant vaginal lesion tx
Stage I: radiation and surgical excision (radical hysterectomy, upper vaginectomy, bilateral pelvic lymphadenectomy)
Stage II-IV: Chemoradiation
Least common site for carcinoma of female reproductive system
Fallopian tubes
Usually serous epithelial carcinoma
Most common type of hydatidiform Mole (Benign GTN)
Complete mole
46 XX or 46 XY completely of paternal origin
2 sperm fertilize an empty egg or 1 sperm with reduplication
15-20% risk of progression to malignant sequelae
Partial or incomplete mole
Often triploid XXX, XYY, XXX with chromosome complement from both parents (usually single ovum fertilized by 2 sperm)
Low risk of progression to malignant sequelae (<4%)
GTD dx
Quantitative b-hCG levels (tumour marker) abnormally high for gestational age
U/S Findings:
- Complete: no fetus (snow storm due to swelling of villi)
-Partial: molar degeneration of placenta +/- fetal anomalies, multiple echogenic regions corresponding to hydropic villi and focal intrauterine hemorrhage
GTD tx
Suction D&C with sharp curettage and oxytocin
Rhogam if Rh -ve
Consider hysterectomy
GTD monitoring
Contraception required to avoid pregnancy during entire F/U period
Serial bhCGs weekly until neg x 3 (usually takes several wk) then monthly x6-12mo prior to trying to conceive again
Increase or plateau of bhCG indicates GTN
Invasive mole or persistent GTN
Dx made my rising or plateau in bhCG, development of metastases following tx of documented molar pregnancy
Choriocarcinoma
Type of GTN
Often present with symptoms from metastases
May follow molar pregnancy, abortion, ectopic or normal pregnancy
If hematogenous spread is suspected, do NOT biopsy
Placental-site trophoblastic tumour
Type of GTN
Rare aggressive form of GTN Abnormal growth of intermediate trophoblastic cells
Low bhCG, production of human placental lactogen, relatively insensitive to chemotherapy
Most common metastasis location for GTN
Lungs
GTN treatment
Mostly chemotherapy
Can consider hysterectomy if fertility not desired
GTN monitoring
Contraception to avoid pregnancy during entire F/U period
Stage I, II, III: weekly bHCG until 3 consecutive normal then monthly x 12mo
Stage IV: Weekly bHCG until 3 consecutive normal then monthly x 24mo
GTN dx
bhCG plateau: <10% drop in bHCG over 4 vales in 3wk OR
bhCG rise: > 20% in any two values over 2wk or longer OR
bhCG persistently elevated >6mo OR
metastases on workup
Etiology of female infertility
Ovulatory disorders (25%) Endometriosis (15%) Pelvic adhesions (12%) Cervical pathology (5%) Uterine pathology (<5%)
Premature ovarian failure etiology
AI disease (most common)
Toxins (chemo)
Chromosomal (ie. Turner’s, Fragile X)
Estrogen and coronary artery disease
Lower E levels (ie. women who undergo oophorectomy, premature ovarian failure, or go into early menopause) have higher rates of CAD
Estrogen and endometrial cancer
Higher E levels (ie. ERT) a/w endometrial CA
Medroxyprogesterone injection for contraception
Prevents ovulation, thins uterine lining
q3mo
May be used in BF women at 6wk PP
Delayed fertility after discontinuation (~10mo)
Liver dz is absolute C/I
Reduces bone mass density (each Ca and Vit D rich foods)
Most common sites of endometriosis in pelvis
