==Epididymis==
*'''See [[Epididymis and Vas Deferens|Epididymis Anatomy]]''' Chapter Notes
*'''Functions (3):'''
*#'''Sperm transport'''
*#*The principal mechanism responsible for moving spermatozoa through the epididymis is probably the spontaneous rhythmic contractions of the contractile cells surrounding the epididymal duct
*#'''Sperm storage'''
*#*After migration through the caput (head) and corpus (body) of the epididymis, spermatozoa are retained in the cauda (tail) epididymis for varying lengths of time, depending on the degree of sexual activity
*#'''Maturation of spermatozoa'''
*#*'''Maturation changes (4):'''
*#*#'''Improving cell membrane structural integrity'''
*#*#'''Increasing fertilization ability'''
*#*#'''Improving motility'''
*#*#'''Increased capacity for glycolysis'''
*#*'''Sperm fertility maturation in humans is, in most part, achieved at the level of the distal corpus (body) or proximal cauda (tail) epididymis'''
*#**'''Clinical implication: in men with congenital absence of the vas deferens or epididymal obstruction from vasectomy, sperm retreival should target the cauda (tail) for better sperm motlity compared to the caput (head)'''
*#Function influenced by temperature
*Fate of unejaculated sperm unknown
*Testosterone and DHT are in high concentration
