Repro Flashcards
What ligament carries the uterine blood supply?
Ovarian blood vessels?
Cardinal ligament
Suspensory ligament of the ovary
How would a radical prostatectomy cause erectile dysfunction?
Cavernous nerves carrying parasympathetics to the penis travel near the prostate and can be damaged during removal
Female equivalent of bulbourethral glands (after prostate)
Vestibular (bartholin) glands (dorsal vestibule)
Female equivalent of prostate gland
Paraurethra (skene) glands
What does the gubernaculum form in the female?
Ovarian ligament (ovary-uterus) + round ligament of the uterus (uterus-labia majora)
What reproductive structures would form if Sertoli cell development was disrupted?
Both male and female internal genitalia
No MIF = paramesonephros never regress
Leydig cells still make testosterone = mesonephros develop
Why can obese males become testosterone deficient?
More adipocytes = increased amortize activity = depletes normal testosterone production by converting it to estrogen
How would exogenous testosterone increase risk for cardiovascular disease?
Increases LDL and decreases HDL
Clinical use for finasteride?
Flutamide?
Finasteride (5a-reductase inhibitor) - DPH, male-patterned baldness
Flutamide (testosterone R inhibitor) - prostate CA
What causes: Female pseudohermaphrodite (XX + ambiguus genitalia) Male pseudohermaphrodite (XY + ambiguus genitalia)
Female = congenital adrenal hyperplasia Male = androgen insensitivity syndrome
Normal female external genitalia + no internal genitalia + bilateral lumps in labia majora
Androgen insensitivity syndrome - labs will show increased LH and testosterone
External = no DHT, default female
Internal = Sertoli cells produce MIF to cause paramesonephros to regress, but testosterone cannot maintain mesonephros development
Testes in labia majora = SRY gene from Y chr comes before testosterona/DHT to induce testis formation
Ambiguus genitalia until puberty
5a-reductase deficiency - labs will show normal testosterone and LH
No DHT = default female external genitalia
Testosterone increases enough during puberty to cause external genitalia to masculinize
Primary amenorrhea + anosmia
Kallmann syndrome - impaired migration of cells that secrete GnRH and that form the olfactory bulb

Testicular lump + gynecomastia (without unique histology findings)
Stroll cell tumor - secretes estrogen

Bowenoid papulosis = red papules on penis of younger men
Only Bowen and Queyrat progress to SCC
Why is the mechanism for Tamsulosin unique?

How many days after ovulation can fertilization occur? When does implantation occur?
Fertilization - within 1 day
Implantation - 6 days after ovulation
How does suckling affect hormones of lactation?
Increases prolactin (milk production, suppress ovulation) and oxytocin (milk let down)
What must be supplemented to infants that are exclusively breast fed?
Vitamin D
What is the order of Tanner stage development for girls?
Breast bugs - pubic hair - menarche
Which birth control method can decrease bone mineral density?
Depo-provera shots (progestin-only)
Vulvar pruritis + smooth white plaques + thin epidermis
Lichen sclerosis - increases risk for SCC
What is the main risk factor for vaginal adenoCA?
DES exposure in utero (retained columnar cells in vaginal mucosa) - also causes T-shaped uterus
Grape-like clusters in the vagina of a young girl
What is the histological marker?
Sarcoma botryoides
Desmin + (rhabdomyosarcoma, has cross-striations)
How do E6 and E7 protein expression in HPV cause cancer?
E6 degrades p53, E7 inactivates Rb
What is the mechanism of Danazol?
Androgen R PA
What are the 2 indications for Danazol?
Endometriosis (inhibits FSH/LH to suppress cycles) and hereditary angioedema (stimulates C1 esterase inhibitor synthesis)
What are the 3 most common gynecological tumors?
Endometrial (best prognosis) > ovarial (worst prognosis) > cervical
What is the mechanism of Leuprolide?
What is the mechanism of Clomiphene?
Leuprolide - GnRH analog (continuous antagonist, pulsitile agonist)
Clomiphene - SERM estrogen antagonist in the hypothalamus (only works as an agonist)
= both are used to stimulate ovulation, but Leuprolide can also be used to suppress cycles (leiomyomas, endometriosis)
Enlarged tender uterus
Enlarged non-tender uterus
Tender - adenomyosis
Non-tender - leiomyoma
What type of estrogen is increased in PCOS and why? What does this cause?
Estrone - elevated androstenedione is converted by peripheral aromitase into estrone
Chronic estrone elevation suppresses follicular development
What is the primary cause of PCOS?
Hypothalamic/pituitary dysfunction causing more LH to be secrete than FSH
What is the 1 non-reproductive side effect of clomiphene?
Visual disturbances (retinal toxicity)
