- (Back little bridge thing)
3
Q
What are glans?
A
- The head of the penis
- It is richly endowed with nerve endings
4

- (Bottom of tip)
5
Q
Urethral opening
A
- Where pee and semen come out
6

7

What is the Scrotum?
A
- The pouhc of skin of the external male genitals that enclose the testes
8
Q
What are internal structures of scrotum?
A
- Seminiferous Tubules
- Epididymis
- Vas Deference
- Spermatic Cord
- Testis
- Cremasteric Muscle
9
Q
What is Seminiferous Tubules
A
- Creates Sperm
- Located in Testes
- Thin Coiled structures in which the testes travel through
10
Q
What is Epididymis
A
- Located right above testes/ On the back of each testis
- Sperm goes here after being Created
- Sperm matures here
11
Q
What is Vas Deferens
A
- Sperm held in Epdiidymis eventually drains into Vas Defrens
- A long thin duct that goes up through scrotum inside spermatic cord
12
Q
Cremasteric Muscle Fibers
A
- Influence the Position of the testis in scrotal sac
- These muscle can be voluntarily contracted
- In Spermatic Cord
13
Q
What Is cut during a vasectomy
A
- Vas Deferens
14
Q
Reproductive and Prostate stuff picture
A
- Seminal Vesicle
- Prostate gland
- Cowper’s gland
- Root of Penis
- Rectum Anus
15
Q
Seminal Vesicle
A
- Two Small glands adjacent to the end s of the vas deferens that produce most of the liquid sperm travels in (70%)
- Fluid is rich in Fructose
16
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?
A
- 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
What are Erections Controlled by?
A
- Automatic Nervous System
21
Q
Two Phases of Ejaculations?
A
- Emission phase
- Expulsion phase
22
Q
What is Emission phase
A
- Gets sperms to top of urethra
23
Q
What is Expulsion Phase
A
- Gets Sperm out of body
- Takes 3-10 seconds
24
Q
Ejaculations are ….
A
- A Spinal Reflex
25
What are Noncancerous Testicular Masses?
- Varicocele
- Spermatocele
- Hematocele
- Testicular Torsion
- Cryptorchidism
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
29
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

* 90% of 90 yearolds
o Last Resort they will use a baloon up the urethra to expand it
34
