Q

Prostate Gland

A
  • Structure the size and shape of walnut
  • Located at base of bladder
  • Ejacutlaory Ducts and Urethra pass through this gland
  • Produces 30% of semen
  • Very basic to help counteract vagina acidity
17
Q

Cowper’s Glands

A
  • Two pea Sized glands located alongside the base of the urethra in the male that secrete precuum
  • Goal is to lubricate urethra
  • Can still have live sperm depending on last erection
18
Q

What is the root?

  • The portion of the penis that extends internally into the pelvic cavity
19
Q

What is the Path of Sperm

A
  • Sperm is is created in Seminiferous Tubules
  • Sperm moves into Epididymis (20 foot long coiled tube)
  • Sperm matures in Epididymis over 2-7 weeks (this helps get rid of abnormal sperm)
  • Sperm then goes up Vas Deferens
  • Passes by Seminal Vesicle where 70% of seminal fluid is produced
  • Passed Prostate gland where 30% of seminal fluid is produced where it turns into combat Acidic vagina
  • Waits in ejaculatory duct
  • Cowper Gland Produce precum to lubricate urethra
20
Q

21
Q

26
What is Varicocele?
- Dilation of the blood vessels in spermatic cord - Creates a ache in scrotum - Goes away if a male lies down for a minutes - TEMPORARY
27
o Spermatocele
* Cyst * Forms above the epiodlimyis * Filled of dead sperm * Ussually no symptoms accept for a physical feeling * No one often knows how it forms * Comonn mostly between men 40-60
28
o Hematocele
* Blood Filled Cist * Results after a blow to the testes (Ussually) * Typically no lasting effects * Gets reabsorbed and goes away eventually

o Testicular Torsion
o Testicular Torsion * Spermatic Cord gets tangled * INTENSE PAIN * Cut off blood flow to testes * Requires Surgery * Inherited Possibilities  The Spermatic Cord is not as anchored
30
o Cryptorchidism
* Undescended Testicle * Happens to premature babies * Most Common infant Genital Issue
31
Internal Non Cancerous Issues
- Prostatitis - Benign prostate Hyperplasia
32
o Prostatitis
* Enlarged Prostate  Cause by Inflamation  Often from infection  Shows itself in urinary issues * Pinches Urethra causing peeing issues  Burning Sensation  Problems peeing  To much peeing  Painful erections + Ejaculations * Common in older men  Over 60 yearolds  Can happen at any age * Common in men during their lifetimes
33
* Benign Prostate Hyperplasia
o A Enlarged Prostate * Cells are still normal cells * Its just bigger o If a man lives long enough they will experience this * 50% of men over 60 have a enlarged prostate * 90% of 90 yearolds o Last Resort they will use a baloon up the urethra to expand it

* Testicular Cancer * Accounts for 1-2% of cancer in males * Affects Younger males typically  Between ages of 20-35 * Rates have doubled in past 30-40 years o More Likely to get if * White * Cryptochristilism history o Common symptoms * You can feel the masss * Dull Ache * Fever * Horomone imbalences  Causes male breasts and nipples to be more sensitive o Very Curable Cancer * 90% percent * Radiation + Chemo * Last Resort of removal
36
* Penile Cancer
o More likelt to get if * Large # of sexual partners * Over age of 50 * Lots of STIs in history * Poor Genital Hygeine * Being Uncircumcized * Tobbaco Use
37
* Prostate Cancer
o 30% of men will get this o 2nd leading cause of cancer depth * After lung cancer o The First Two stages are virtually undetectable without a prostate exam * Beginning in stage 3 it begins to spread to other areas o Risk Factors * Old Age * Family History * Being African American o Rectal Exams is used to palpate prostate to check for lumps
