Question 1

44yo nulligravid, not interested in pregnancy, no male partner wants to discuss fertility preservation options. Best step in management?

Answer 1

Expectant management (NOT oocyte cryopreservation)
- Clinical pregnancy rate per thawed oocyte = 4.5-12%
- At 4.5%, would need ~22 oocytes to result in one pregnancy
- Live birth rate = 2-12% for women <38yrs
- Therefore, ASRM does not recommend oocyte vitrification in those older than 38

Question 3

27yo G1P0 at 29wks with hirsutism, PCOS, and bilateral solid ovarian masses. Testosterone 804 mg/dL, DHEAS 150ng/dL, CA-125 wnl. What are the masses, and how do you manage?

Answer 3

Ovarian luteomas -> benign hyperplasia of large lutein cells by HCG
- usually regress 2-3 weeks postpartum –> EXPECTANTLY MANAGE
- yellow-brown solid tumors
- histology: round-to-polygonal cells with eosinophilic cytoplasm. Stain + for inhibin A, neg of AFP.
- other causes of gestational hyperandrogenism: drugs, sertoli-leydig, krukenberg, placental aromatase deficiency
- Luteoma vs Theca-Lutein cysts: both benign
- Luteoma: 47% bilateral, 79% fetal virilization
- Theca-Lutein: almost always bilateral, do NOT cause fetal virilization

29yo with secondary amenorrhea and desire for fertility. Fam hx significant for maternal aunt and uncle with tremor/ataxia syndrome. FSH 112 and 92 1 month apart, estradiol <20, TSH, PRL and karyotype wnl. Next best lab test to order?

Answer 7

FMR1 gene premutation screening (Fragile X)

Primary ovarian insufficiency = <40yrs, at least 4 months of amenorrhea, 2 FSH concentrations in menopausal range at least 1 month apart
- most common etiology is idiopathic

Fragile X: x-linked
- FMR1 gene on long arm of X chromosome, Xq27
- CGG repeats; normal = <45, 45-54 intermediate, 55-200 premutation and assoc with POI, >200 full mutation
- 6% of women with POI will have FMR1 premutation

Other causes of POI: polyglandular autoimmune syndrome, FSH receptor mutations, Turner

Prolog REI - Q7

Question 9

17yo with primary amenorrhea. Tanner IV breasts, Tanner I pubic/axillary hair and blind-ending vagina. Diagnosis?

Answer 9

Androgen-insensitivity syndrome
- X-linked recessive
- mutation in androgen receptor on long arm of X chromosome, Xq
- Testosterone -> dihydrotestosterone by 5 alpha reductase –> formation of penis, scrotum, and prostate
- testosterone converted to estradiol by aromatase

Swyer = phenotypically female but 46, XY with complete gonadal dysgenesis
- inactivating mutation of sex-determining region of Y gene

Klinefelter = 47, XXY
Turner = 45, XO

Question 10

28yo G1P0 with positive UPT, hx hyperprolactinemia. MRI shows pituitary macroadenoma measuring 1.2cm and abutting optic chiasm. Currently tolerating cabergoline and has mildly elevated PRL. Given current pregnancy, the most appropriate management is…?

Answer 10

Switch to bromocriptine
- both dopamine receptor agonists
- cabergoline: more potent, improved patient adherence (2x weekly dosing), and fewer adverse effects
- bromocriptine: not shown to increase congenital malformations
- cabergoline also showed to be safe, but there is much more data on bromocriptine so currently it is the preferred medication in pregnancy

• Remember visual-field testing every trimester
• Monitoring prolactin levels not helpful during pregnancy
• For MICROadenoma or macro but away from optic chiasm, stop DA agonist once pregnancy confirmed. Start bromocriptine if tumor growth evident.

Question 11

33yo G2P2 5 months postpartum with heat intolerance, fatigue, and occasional palpitations. HR 110 bpm. TSH low, mildly elevated free thyroxine. Best next step?

Answer 11

Metoprolol

Postpartum thyroiditis:
- Usually 3-6 months postpartum in patient who was euthyroid before pregnancy
- prevalence 5%, likely to recur in up to 70% of subsequent pregnancies
- major risk factor: positive thyroid antibodies in first trimester +gDM
- classic form: thyrotoxicosis followed by transient hypothyroidism, then return at 12mos
- Differentiate between postpartum thyroiditis and Graves with goiter with bruit and ophthalmopathy

Question 12

38yo with primary infertility. AMH 0.75, day 3 FSH 14. Normal HSG. Partner with oligospermia, 2.2mil, 35% motility, and 1% morphology and varicocele. Best next step?

Answer 12

IVF with intracytoplasmic sperm injection (ICSI)
- NOT varicocelectomy
- Varicoceles in 15% population and 40% in infertile male population
- Most are left sided because of drainage of left spermatic vein into higher resistance left renal vein; right spermatic vein drains into vena cava
- surgical intervention when clinically palpable, established infertility, normal female, and male has 1+ abnormal semen parameters
- In example, multiple abnormal semen parameters + female 38 with diminished ovarian reserve

Answer 14

IVF and delayed frozen embryo transfer (NOT letrozole and IUI)

• Oligoasthenospermia
• Semen analysis shows low concentration, low motility, low volume, and only 2 million total motile sperm
• For IUI to be successful, generally more than 10 million total motile sperm is required

Question 15

32yo G0 with hx of secondary amenorrhea for 1 year. Normal FSH, TSH. Low estradiol. Prolactin 80. MRI shows 5mm pituitary adenoma. Wants pregnancy in next 2-3 months. Next best step in management of amenorrhea?

Answer 15

Cabergoline

Prolactin >250mcg/L most likely associated with macroadenoma (>10mm)

• Hyperprolactinemia causes amenorrhea because prolactin inhibits GnRH from hypothalamus -> low FSH/LH (FSH may be low-to-normal due to long half-life though)
• Suppress PRL with dopamine agonists, replace estrogen with OCPs or estrogen
• Cabergoline = first line rather than bromocriptine (higher efficacy)
• Stop dopamine agonists when pregnancy confirmed (cross placenta)
• Cabergoline linked to cardiac disease

Question 16

68yo with 8yr history of hair growth on face, chest, male-pattern baldness, and deepening voice. Hx PCOS. BMI 27, BP 126/78. Morning testosterone 127, FSH 98, LH 52, DHEAS 35, morning cortisol 8. TVUS showed R ovary 5x4, left 4.8x3.1. Most likely diagnosis?

Answer 16

Ovarian hyperthecosis (NOT sertoli-leydig cell tumor, CAH, or cushing syndrome)

• The menopausal ovary continues to produce testosterone and androstenedione + decrease in sex hormone-binding globulin = relative increase in testosterone but should not cause severe hirsutism/virilization
• Normal hair growth can include some terminal hairs on upper lip/chin but not shoulder/chest/abdomen
• Score >8 on Ferriman-Gallway scale = hirsutism in premeno women
• Think tumor when testosterone >200 (ovarian) and DHEAS >700 (adrenal) in premenopausal. Postmenopausal: testosterone >100
• Most common cause of hirsutism on postmeno = ovarian source
• tx of hyperthecosis in postmeno = BSO
• 3 types of ovarian neoplasms that can cause hyperandrogenism: Sertoli-Leydig, lipoid cell tumor, and hilus cell tumor

Prolog REI - Q16

Question 17

25yo with BRACA1, wants pregnancy in next 5 years. Contraceptive method that provides greatest protection against subsequent cancer is…?

Answer 17

Estrogen+progesterone OCP

BRCA1 = 65-74% lifetime risk breast cancer, 39-46% ovarian (serous or endometrioid)

OCPs can decrease risk of ovarian cancer by as much as 80% (duration of benefit unknown)
- Small but significant increase in breast cancer risk associated with OCPs, esp in BRCA, but breast cancer easier to surveil than ovarian
- Suppressing ovulation with implant would also likely decrease ovarian cancer risk but hasn’t been studied enough yet

Answer 20

IVF (NOT operative laparoscopy)
- When endo is moderate or severe and hx of multiple surgeries, IVF is most effective. Also has low AMH. IUI less effective.

• OCPs, GnRH agonsits/antagonists are ineffective for endo-related infertility
• Elagolix: GnRH antagonist -> short term suppression of HPO axis. Can use up to 2 years.
• Laparoscopic ovarian cystectomy may be recommended with endometriomas >3cm in diameter

Answer 21

Etonogestrel/Ethinyl estradiol vaginal ring
- Not OCPs due to gastric bypass, not Depo due to weight gain, not IUD due to bicornuate uterus

• Increased adipose -> increased aromatase -> increased estrogen -> HPO axis suppressed -> decreased FSH and LH -> ovulatory dysfunction
• Insulin stimulates testosterone production through ovarian insulin-like growth factor 1 receptor -> ovulatory dysfunction

Question 22

28yo at 33wks presents with increasing facial, chest, and abdominal hair growth + voice deepening and male-pattern baldness. Testosterone 1032. US shows bilaterally enlarged ovaries, left 11x9x7 with multiple cysts with spoke-wheel appearance. Right ovary 10x8x6 with cysts. Most likely diagnosis?

Answer 22

Hyperreactio luteinalis aka theca lutein cyst (other options: hilar cell tumor, luteoma of pregnancy, sertoli-leydig tumor)

• most common cause of hyperandrogenism in pregnancy
• bilateral
• most asymptomatic, 20-30% can cause hirsutism/virilization
• luteinization and hypertrophy of ovarian thecal cells stimulated by hcg

Pregnancy luteoma: may be bilateral or unilateral, benign

17-hydroxyprogesterone (17-OHP) - NOT DHEA-s Nonclassic congenital adrenal hyperplasia (CAH): autosomal recessive mutation in CYP21A2 gene on chromosome 6 that results in 50-80% reduction in 21-hydroxylase activity - symptoms overlap with PCOS -> distinguish difference with 17-OHP - Level >200 and <800 ng/dL => further test with cosyntropin (ACTH) stim test - >800 confirms diagnosis of CAH Both PCOS and CAH can have mildly elevated levels of androstenedione DHEAS comes from the adrenal gland, but a tumor would present with rapid hyperandrogenism and virilization (not since puberty in example) Prolog REI - Q51

Question 52

16yo sexually active girl is referred by dermatology who would like to start her on isotretinoin for acne. In addition to condoms for contraception, the hormonal contraceptive that is most likely to improve her acne is...?

Answer 52

Combined OCPs Acne first line: benzoyl peroxide or topical retinoid. Next: topical clindamycin and dapsone. Next: PO tetracyclines or OCPs. Next: Isotretinoin. OCPs decrease androgen production and increase sex hormone-binding globulin production Prolog REI - Q52

Lab tests reveal macrocytic anemia, a 25-hydroxyvitamin D level of 8, and albumin level of 2.5. The most likely weight loss procedure that was performed in this patient is...?

Answer 55

Roux-en-Y gastric bypass - malabsorptive - most common nutritional deficiencies: B12, calcium, D, folate, protein, and iron - should have CBC, vit D, calcium, and ferritin checked each trimester of pregnancy - have MFM, bariatric surgeon, and nutritionist on board - Decreased risk of HTN, gDM, and macrosomia but increased prevalence of low birth weight Prolog REI - Q55

Question 56

19yo calls your office because a partner's condom broke during intercourse the previous night. She also had sex 4 days ago with a different partner and did not use contraception. The most appropriate and effective form of emergency contraception to prevent pregnancy in this scenario is...?

Answer 56

Ulipristal acetate (NOT copper IUD) - Copper IUD within 5 days of intercourse is the most effective method of emergency contraception, but risk of PID and subsequent tubal damage is increased among patients with multiple sex partners therefore not the best for this patient - copper IUD also good as it can be used in any BMI Combined OCPs regimen: 100mcg ethinyl estradiol + 0.5mg levonorgestrel, 2 doses 12 hrs apart after intercourse. Risk of pregnancy 2.9%. Progestin-only: 0.75m levonorgestrol, 2 doses 12 hrs apart (single dose has similar effectiveness). LNG more effective than combined OCPs and less nausea. Risk of pregnancy 1.1-2.4% Ulipristal acetate is more effective than LNG and for up to 5 days and in women of all weights Prolog REI - Q56

Question 57

32yo G4P4 with severe dysmenorrhea. TVUS showed enlarged uterus containing numerous anechoic myometrial lacunae and a diffuse heterogenous myometrial echotexture. Unsure on future fertility. Previous LNG IUD was expelled and she doesn't want another. Best next step in management?

Answer 57

Continuous OCPs - induce decidualization and subsequent atrophy of the endometrium - progestin component suppresses aromatase and estradiol-induced vascular-endothelial growth factor and cyclooxygenase-2 expression Adenomyosis: heterotopic endometrial glands and stroma in the uterine myometrium - Difference in anterior and posterior myometrium thickness on US - Monophasic low dose OCPs have good efficacy, high tolerability, and low cost - LARCs also tend to work well - Elagolix (oral GnRH antagonist) would likely be effective but not first line due to cost Selective progesterone modulators (mifepristone, asoprisnil, and ulipristal acetate) are on the rise and upcoming options Prolog REI - Q57

Parents are discussing puberty blockers (GnRH agonist) and eventual androgen therapy. The best time to freeze oocytes in this patient is...?

Answer 65

Before testosterone initiation The Endocrine Society recommends initiating sex hormone treatment at 16 years or older for adolescents who have confirmed gender dysphoria and sufficient cognitive ability to understand the implications Pubertal suppresion treatment does not have a long term effect on fertility / ovarian function after cessation of treatment, therefore can await preservation until after puberty but before testosterone initiation. Also recommend wait until after puberty to confirm plan to complete transition as this is a time for further exploration. Prolog REI - Q65

TXA (NOT estrogen/progesterone containing products due to breast cancer hx) Normal menses: 21-35 day cycle, bleeding 2-6 days. 30-60mL per cycle. - Heavy = >80mL or >7 days TXA reduces blood loss by 30-55% - antifibrinolytic, blocks conversion of plasminogen to plasmin which reduces fibrinolysis - contraindicated in hx of VTE and acquired color vision abnormalities Prolog REI - Q94

Question 95

41yo presents with heavy menstrual bleeding and pelvic pressure. US shows 9x7cm anterior intramural fibroid. She desires uterine retention and minimally invasive approach. You counsel her that the procedure will most likely require the use of power morcellation to remove it. the most likely complication from her procedure is...?

Answer 95

Failed laparoscopy (NOT dissemination of sarcoma cells) Minimally invasive surgery: shorter hospitalization, reduced blood loss, lower pain, lower incidence of postop ileus, shorter recovery - complication rate 0.4-3%, technically more challenging - does not have increased risk of visceral injury vs laparotomy but has higher urologic injuries. Vascular injuries about the same. Uterine sarcomas account for 3-5% all malignancies. Most common leiomyosarcoma 63%. - US FDA estimated 1 in 225 to 1 in 580 women will have occult sarcoma - ACOG says 2 in 1,000 - annual incidence of sarcoma is 0.64 per 100,000 women THUS, greater risk of laparoscopic complications than dissemination. - ACOG still recommends laparoscopic approach to myomectomy with power morcellation in properly selected candidates - Lowest incidence of sarcoma in women <35, highest >65yrs. - ACOG advisory says the risk of unexpected leiomyosarcoma may range from less than 1 in 770 surgeries to 1 in 10,000 Prolog REI - Q95

DEXA shows bone mineral density 2 standard deviations below the mean for her age group. In addition to nutrition counseling and CBT, next best step in managing her low bone mass is...?

Answer 96

Transdermal estradiol with cyclic oral progestin Functional hypothalamic amenorrhea (reduced GnRH -> low FSH, LH). - may occur with weight loss, vigorous exercise, and stress - amenorrhea, infertility, low bone mass Transdermal estradiol and cyclic progestin improves bone mineral density. - Endocrine society advises against use of OCPs for sole purpose of regaining menses and improving bone density. May mask return of spontaneous menses and bone loss may continue. OCPs also downregulate insulin-like growth factor I, a bone-trophic hormone. Bisphosphonates and SERMs should NOT be used in adolescents because they have a long half life and are retained in bone for years, therefore concern for health of a future fetus. Prolog REI - Q96

Question 97

25yo is on combined OCPs because of a history of hypogonadotropic hypogonadism. Now interested in pregnancy. The ovulation-induction medication that is most likely to be successful given her condition is...?

Answer 97

Urinary human menopausal gonadotropins NOT clomid, letrazole, or recombinant FSH Clomid = SERM, acts on hypothalamus, increases gonadotropin release Letrazole = aromatase inhibitor, prevents testosterone into estradiol and stimulates increasein FSH Hypogonadotropic hypogonadism patients lack FSH and LH. FSH alone might not yield optimal results. Urinary human menopausal gonadotropins contain both FSH and LH. Luteal progesterone support is also recommended and shown to improve outcomes in women undergoing gonadotropin therapy. Prolog REI - Q97
