Editing Scrotum & Spermatic Cord (section)

== Gross Structure ==

* '''Median raphe'''
** Runs longitudinally in the midline from the urethral meatus to the anus
** '''The arteries, veins, lymphatics, and nerves of the scrotum do not cross the raphe'''
** Deep to the raphe, the scrotum is divided by a septum into two compartments, each containing a testis.

* '''<span style="color:#ff0000">Layers of the anterior abdominal wall extend to form parts of the scrotal wall:'''
** '''<span style="color:#ff0000">Scarpa fascia extends to form the dartos smooth muscle (and the dartos fascia of the penis)'''
***'''<span style="color:#ff0000">Also continuous with Colle’s fascia'''
****Clinical implication: [[Fournier's Gangrene]] can involve the dartos smooth muscle of the scrotum and spread to involve the scarpa fascia of the abdominal wall. However, the spread to the anal margin is limited posteriorly by the attachment of the Colles' fascia to the perineal body.
** '''<span style="color:#ff0000">External oblique extends to form the external spermatic fascia</span>'''
***Clinical implication: During debridement for Fournier's Gangrene, the external spermatic fascia of the scrotum and the external oblique muscle can usually be spared.
** '''<span style="color:#ff0000">Internal oblique extends to form the cremaster muscle</span>''' 
** '''<span style="color:#ff0000">Transversalis fascia extends to form the the internal spermatic fascia</span>'''
* '''The parietal and visceral tunica vaginalis are peritoneal derivatives that surrounds the testis''' with a mesothelium-lined pouch.
** '''The tunica vaginalis is continuous with the testis posterolaterally at its mesentery, where it is attached to the scrotal wall.'''
* '''The gubernaculum fixes the testis at its inferior pole'''
* '''Absence of gubernaculum and testicular mesentery is known as Bell-Clapper deformity and predisposes testicle to torsion'''
