Male generative organs. — The male generative organs consist of 

 the following structures : — 



Testes, two glandular organs which produce the spermatozoa. 



Vas Deferens 



Seminal Vesicles 



Ejaculatory Ducts 



The Scrotum 



The Spermatic Cords 



The Penis 



The Urethra 



The Prostate Gland 



Cowper's Glands 



Testes. — The testes are two glandular organs which are sus- 

 pended from the inguinal region by the spermatic cords, and are 

 surrounded and sup- 

 ported by the scrotum. 

 Each gland weighs from 

 five to eight drachms 

 (18.5 to 30 grams) and 

 consists of two por- 

 tions : (1) the testicle 

 proper, and (2) the 

 epididymis. 



(1) The testicle 

 proper is ovoid in shape 

 and covered exteriorly 

 by fibrous tissue which 

 sends incomplete parti- 

 tions into the central 

 portion of the gland, 

 dividing it into commu- 

 nicating cavities. In 

 these cavities are wind- 

 ing tubules which are 

 surrounded by blood- 

 vessels and held together by interstitial tissue. These tubules 

 inosculate in a sort of mesh (rete testis) and finally all unite in the 

 epidid.>Tnis.
