Q

Male devo process?

What cell types make what hormone? What do they do?

A

SRY gene of Y chromo produces TDF (testes devo factor)

From this comes:
Sertoli–>MIF–l Female devo
Leydig—>Androgens–>Male devo (testo=internal male, DHT=external male genitalia)

Q

Suspensatory Ligament (Infundibulopelvic ligament) of ovaries. Contains?

Q

Leydig Cell tumor unique feature?

A

Reinke crystals

19
Q 
Testicular Tumor Markers:
Seminoma
Yolk Sac tumor
Choriocarcinoma
Embyronal carcinoma
A

Seminoma: Placental alkaline phosphatase/LDH
Yolk Sac tumor: Alpha feto protein
Choriocarcinoma: Beta-hCG
Embyronal carcinoma: Alpha feto AND beta hCG

20
Q

Presentation of complete androgen insensitivity?

A

Tall, Large breasted, hairless, blind vaginal pouch, testis in labia—remove post puberty to prevent seminoma risk

21
Q

OCP mechanism?

A

Continous levels of E2/P4 which prevent LH surge thus no ovulation

22
Q 
Where does the majority of a females:
DHEAS
Androsteindione
Testosterone 
DHT come from?
A

DHEAS/Androsteindione comes from adrenals. (AnDRo from ADrenals)
DHT/Testosterone comes from ovaries.

23
Q

Increased estrogen exposure puts woman at risk for? Examples?

A 
Breast cancer.
Anvulatory cycle (also at risk for endometrial), early menarche, late menopaus, obesity, increased breast tissue
24
Q

Best marker of a healthy pregnancy towards end of preg?

A

E3 levels made by placenta. E2:E3 ratio remains 1:1 (competing for same estrogen receptor) until the end when E3 increases dramatically causing uterine contractions.

25
Q

Cancer that can produce T3/T4?

A

Struma Ovarii (ovarian teratoma)

26
Q

Oocytes arrested in what phase until preovulation?

Oocytes arrested in what phase postovulation until fertilized?

A

Prophase I: O-vulation prOphase

Metaphase II: until egg MET sperm.

27
Q

Best test to Dx menopause?

A

FSH levels—they are the first to increase. (logically makes sense since this is a decline in follicles and hypo/pit are trying to stimulate them)

28
Q

Male presents to you for infertility. He has is tall and has long arms. What do you suspect?
What other things might he have?
What test could you do? Hormone levels?

A

1) Hypogonadism due to Klinefelter’s XXY.
2) Testicular Atrophy (small firm hard testis), Gynecomastia, Eunuchoid body habitus, female hair distribution. Possibly developmental delay
3) Look for barr body showing x chomo inactivation.
4) Issue at gonads thus increased FSH/LH. Decreased inhibin/test. Increased Estrogen.

29
Q

Most common cause of Primary amenorrhia? Why?
Accompanying presentation?
How to assist with Preg?

A

1) Turners, XO. Dt ovarian dysgenesis (streak ovaries***)
2) Short stature, webbed neck (posterior Cervical hygroma), Lymphatic defects in general. Shield chest, widely space nipples. Horsehoe kidney, Preductal Coarcatation, bicuspid aortic valve
3) Oocyte donation (cuz dysfunctional ovaries) and hormone replacement (E2, P4)

30
Q

2 Tx for a female that comes in with too much B-hCG for her gestational age?

A

1) Dilation and curettage–risk for asherman’s

2) Methotrexate

31
Q

Female presents with signs of appendicitis…

You do the right thing and do a quick pregnancy test, and you see low levels of BhCG, what do you think?

A

Atopic pregnancy, can mimic signs of appendicitis. There will be lower than normal pregnancy levels of BhCG

32
Q

Condyloma Accuminata vs Lata?

A

Accuminata=HPV 6/11

Lata=Syphilis (l’s in lata and syphilis)

33
Q

Where does cervical carcinoma invade? Causing?

A

Likes to invade locally. Will go and obstruct Ureters leading to hydronephrosis and renal failure

34
Q

Landmark for pudendal nerve block?

A

Ischial Spine

35
Q

Cryptorchism at risk for what?

A

GERM CELL TUMORS

36
Q

3 Major risk factors for ED?

A

Diabetic, Atherosclerosis, and Coronary Heart Disease

37
Q

Common side effect of Nitrates and PDE-5 inhibitors?

A

Headache, Flushing, HOTN (why you can’t combine them.

38
Q

Flutamide vs Finesteride?

A

Flutamide: Andro Receptor Antagonist (“Doug Flutie’s a girl”)-tx for Prostate Cancer
Finesteride: 5-Alpha Reductase inhibitor; Tx for BPH, and allopecia

39
Q

Fertilization most commonly occurs in?

A

The ampulla of uterine tubes (2nd part of tubes)

40
Q

Urachal vs Vitelline ducts?

A

Urachal for U-rine

Vitelline connection to GI tube

41
Q

Cavernous Nerves of penis do they come from (2 levels)? Damage likely during what surgery? Causing what?

A

Cavernous nerves of penis from prostatic nervous plexus which comes from Inferior hypogastric plexus.

Damaged during prostatectomy/surgery (they are in the prostate fascial shell of the prostate) resulting in ED

42
Q

OCP’s can cause what liver disease? What else can cause it?

A

Hepatic Adenoma. Anabolic Steroids

43
Q

Maternal Diabetes puts child at risk for?

A

Macrosomia (tractional type birthing issues=eg erb palsy), transposition of the great arteries, and Caudal Regression syndrome
