Anatomy of Male Reproductive System Flashcards
Where is the Male Peritoneum?
Descends on anterior abdominal wall to level of the pubic symphysis
When the male Peritoneum passes the fundus of the bladder what Space does it form?
Retropubic Space
When the Peritoneum folds from the base of the bladder over the rectum, what Pouch lies here?
Rectovesical Pouch
What sort of Bacteria can be formed in or near the Rectovesical pouch?
Absceeses can be drained transrectally
What does the Male internal Genitilia consist of?
Testes Epididymas Ductus Deferens Seminal Vesicles Ejaculatory Ducts Prostate Bulbourethral glands
What does the Male External Genitilia consist of?
Urethra
Scrotum
Penis
What are the Testes?
Paired male gonads
What glands of the Testes produce sperm and hormones?
Ovoid Glands
Where is the Testes?
In the scrotum by spermatic cord
Describe outer surface of the Testes?
Tough fibrous - Tunica albuginea
Describe the Epididymas?
Elongated postolateral ridge
What is the Testes partially surrounded by?
Tunica Vaginalis - double layered membranous sac
Where is Sperm produced?
Seminiferous tubules of the testes
What is the Route of Sperm?
Seminiferous tubules - tubuli recti - rete testis - efferent ductules - epididymas - ductus deferens
What is the Major component of the Spermatic Cord?
Ductus deferents
What are the Ductus Deferens?
Paired muscular tubes
Where does the DD convey?
From the epididymas to Ejaculatory duct through inguinal canal to ampulla out the seminal vesicles to prostatic urethra
What is the Dilated part of the tube of DD called?
Ampulla
What forms the Ejaculatory ducts?
Seminal Vesicles
Where does the Ejaculatory ducts open into?
Prostatic urethra
What is a Vesectomy?
Part of the DD is removed and ends tied so sperm is no longer conveyed
What happens to the Sperm after a Vesectomy?
Sperm degenerates within epididymas
What are the Seminal Vesicles?
Elongated paired structure between bladder and rectum
What does the Seminal Vesicle secrete?
Alkaline fructose rich fluid as energy source for sperm
Where does the Seminal vesicle join in the Sperm ejaculation process?
Joins DD to form paired Ejac ducts
Describe the Prostate?
Firm walnut sized accessory gland below neck of bladder
What runs through the Prostate?
Part of male urethra
What does the Prostate produce?
Milky fluid that aids sperm motility
Where does the Ejac ducts open into the Prostate?
Seminal Colliculus - elevated portion of urethral crest
What is the Prostate covered by?
Fibrous capsule incorporating prostatic plexuses of veins and nerves
What is surrounding the Prostate?
Fibrous prostatic Sheath
What is the Prostate base associated with?
Neck of the Bladder
What is the Prostate apex associated with?
External urethral spincter
How does the Prostate receive Arterial Supply?
Inferior Vesical Artery
How do you Palpate the prostate gland and what do you look for?
Insert lubricated finger into rectum, palpate through anterior rectal wall - gland should feel smooth and rubbery walnut sized
What Symptons can Cause Benign Prostatic Hyperplasia?
Lower UT - Need to wee but cant go - Risk of this increases with age
How would you Remove some of the Hyperplasia?
Through Transurethal resection of prostate TURP through head of penis
Describe Cancer of the Prostate?
Slow-growing may metastize to vertebral column and pelvis via Lymph system
How can you Diagnose Prostate Cancer?
DRE, PSA, TRUS, Biopsy and imaging
What are the Treatment options for Prostate Cancer?
Watchful waiting, Surgery, Chemo, Radiotherapy, Hormone treatment
How can you Indicate Prostate Cancer severity?
Staging
Describe Stage 1 of Prostate Cancer?
Cancer in 1 area of prostate
Describe Stage 2 of Prostate Cancer?
Spread to whole of Prostate
Describe Stage 3 of Prostate Cancer?
Spread to Accessory organs aswell whole of prostate
Describe Stage 4 of Prostate Cancer?
Spread all over Internal organs and Chance of spreading to body if reaches Lymph nodes
Describe Bulbourethral glands?
Pea-sized paired glands
Where is Bulbourethral glands located?
In external urethra sphincter in deep perineal pouch
What does the Bulbourethral glands secrete?
Mucoid fluid - Precum
Where is Semen made?
5% in testes
65% in Seminal Vesicles
25% in Prostate
<1% in Bulbourethral glands
