 THE MALE ORGANS OF GENERATION 



THE; male organs of generation include the prostate 

 gland, the penis and the testicles, with their appendages, 

 and the seminal vesicles. 



The Prostate Gland. The prostate gland surrounds 

 the commencement of the urethra, lying in the pelvic 

 cavity behind and below the symphysis pubis and in front 

 of the rectum. It is shaped like a horse-chestnut, measur- 

 ing i \ inches transversely, i inch from before backward, 

 and f inch in depth. It is composed of numerous 

 pouched glands embedded in interlacing bundles of mus- 

 cular tissue, the whole being enclosed in a fibrous capsule 

 (Fig. 156, i). 



The prostate gland surrounds the prostatic portion of the 

 urethra, which is i J inches long. The floor of the prostatic 

 urethra contains a longitudinal ridge, called the verumon- 

 tanum or caput gallinaginis, on either side of which is a 

 slight fossa known as the prostatic sinus. In front of the 

 verumontanum is a depression, the sinus pocularis or 

 uterus masculinus, upon the margin of which are the ori- 

 fices of the ejaculatory ducts. 



Cowper's glands are two small, rounded, yellowish 

 bodies, about the size of peas, situated behind the begin- 

 ning of the membranous portion of the urethra. They 

 open by means of ducts on the floor of the urethra. (See 

 Figs. 156, h, and 157, 6.) 



The penis serves the double purpose as the termination
