*'''See [[Epididymis and Vas Deferens|Epididymis]] Anatomy'''
*'''Anatomy of the Excurrent Ducts'''
**'''Sperm and testicular fluid exit the testes through efferent ducts. These ducts become convoluted when they exit the testes and form the caput of the epididymis'''. At that level, they freely anastomose with one another. '''They all coalesce at the distal caput to form a single epididymal tubule''' '''from the caput-corpus junction all the way to the vas deferens.'''
***'''Clinical implication: puncture of a single tubule for sperm aspiration can be safely performed at the most proximal region of the head of the epididymis''' because there are multiple lobules at this level
****'''Any injury to the epididymis distal to the caput will result in complete obstruction of the entire system on that side'''
**'''Hydrocelectomy and orchiopexy for torsion can result in iatrogenic injury to the epididymis'''
