1
Q
Penis Function
A

Q
Penis Anatomy
A
- Root attaches to lower abdomen/pelvis
- Shaft, cylindrical portion
- Glands, cone shaped end
- Foreskin may cover glands
3
Q
Testis Function
A
- Sperm production in seminiferous tubules
- Sperm storage in epididymis
- Sperm transported to urethra
- Testosterone production
4
Q
Testis Anatomy
A
- Descend from abdominal cavity
- Pair organ located within scrotum
- Associated with epididymis & vas deferens
5
Q
Prostate Function
A
- Secretes fluids to prolong sperm lifespan
- Control urination & ejaculation
6
Q
Prostate Anatomy
A
- Inferior to bladder
- Join with urethra
- Size of large walnut (20g)

15
Q
Testicular Cancer Presentation
A
- Painless testicle enlargement
- Metastasis (lungs, lymph nodes)
- Subtype varies from primary tumour
16
Q
Testicular Cancer Diagnosis
A
- Imaging (ultrasound)
- Testicular lesions (no biopsy)
- Bloodwork for biomarkers
- HCG, AFP, LDH
17
Q

- 60% of tumours are mixed
18
Q
Testicular Cancer Treatment
A
- Surgery (orchiectomy)
- Chemo
- Radiation
19
Q
Inflammatory Disease
A
- Occurs in epididymis & testes
- Testicle swelling, pain
- Fever
- Nausea/vomit
20
Q
Non-Specific Epididymitis & Orchitis
A
- Often related to UTI
- Spread through vas deferens/lymphatics
- Causes varies with age
21
Q
Children Non-Specific Epididymitis & Orchitis
A
- Congenital genitourinary abnormality
- Infection with gram neg rods (E coli)
22
Q
Sexually Active Non-Specific Epididymitis & Orchitis
A
- Younger than 35
- Sexually transmitted pathogens (STI)
23
Q
35+ Non-Specific Epididymitis & Orchitis
A
- Urinary tract pathogens (E coli, pseudomonas)
24
Q
Granulomatous (Autoimmune) Orchitis
A
- Idiopathic
- Suspected autoimmune cause
- Sudden onset
- Testicular tender mass
- Fever
- Mimic of testicular cancer
25
Gonorrhea Components
- Posterior urethra to prostate
- Seminal vesicles
- Epididymis
26
Mumps
- Viral illness in school age child
- Rare testicular involvement
- Orchitis in 20-30% of post puberty cases
27
Tuberculosis
- Begins in epididymis
28
Syphilis
