Male Reproductive Flashcards
Major cancer of 15-34Y
Testicular cancer
Big cause of male sterility
Testicular cancer
Risks for testicular cancer
Family hx, white, HIV esp in AIDS stage, cryptorchidism (testes not descended by 3M, and most not descended by 3Y, longer w/o descension, higher risk of cancer)
Can you get cancer in a teste if it descended with cryptorchidism?
YES (25%)
- if pt has corrected after 12Y or never, 2-6x higher chance of getting T cancer
What kind of tumor is most testicular cancer?
Germ cell tumors
Germ cells
Sperm forming
Seminomas
Rise from immature germ cells
- slow growing, non aggressive
- easy cure with radiation
Non-seminomas
From mature germ cells
- more aggressive, need surgery
CM of testicular cancer
Early - enlarge, painless mass, ache in groin or heaviness in scrotum
Late - frank pain, sx based on metastasis (cough, hemoptysis, swell, back pain, dizzy)
How deadly is testicular cancer?
Very curable if caught in early stage; not too deadly even in late stage
Prostate
Heart shaped gland around the urethra that makes seminal fluid
BPH
nonmalignant growth of epithelial (mechanical obs) and smooth muscle (dynamic obs) cells; both obstruct the urethra
Cause of BPH
unknown; sometimes from lower UTI
Risk for BPH
age, fam hx, race (higher in AfAm, lowest in Asian pop)
BPH theory of hormone imbalance
make T and little estrogen; T dec with time but est stays same of inc slightly, causing an imbalance from growth factors released
DHT accumulation theory of BPH
dihydrotestosterone increase and accumulates and activates growth factor and influences by presence of estrogen
DHT
dihydrotestosterone–made with T and 5-alpha-reductase
What does DHT do?
controls acne, growth of prostate, hair on chest, baldness
