Anatomy of male reproductive system

The testis composed of 900 coiled seminiferous tubules, each 

average more than 5 meters length in which the sperms are 

found. Between the seminiferous tubules are the interstitial 

cells of leydig for synthesis of testosterone. The sperms pass 

from the

seminiferous tubules to the epididymis which is coiled and 

about 6 meters length, this leads to the vas deferens which 

enlarges into the ampulla before entering into the prostate 

gland. The seminal vesicles are two, one located on each side of 

the ampulla, empties into the prostatic end of the ampulla and 

the contents from the ampulla and seminal vesicles pass into 

the ejaculatory duct leading to urethra.
