CHAPTER VIII. 

 REPRODUCTIVE ORGANS IN THE MALE. 



Under this heading are included (i) the testes and 

 their ducts, (2) epididymis, (3) penis, and (4) pros- 

 tate gland. 



THE TESTICLES. 



The testes are two glandular organs for the produc- 

 tion of spermatozoa, suspended in the scrotum by 

 the spermatic cord. Each testicle is about one and 

 one-half inches long, one and one-fourth inches 

 wide, and nearly one inch thick from side to side. 

 The corresponding dimensions of the ovary are, one 

 and one-half by three-fourths by one-half inches. 



The coverings of the testes are, (i) skin, (2) dartos; 

 these two form the wall of the scrotum. The skin is 

 thin and pigmented. The dartos is a reddish tissue 

 continuous with the two layers of superficial fascia 

 of the groin. It is vascular and consists of smooth 

 areolar tissue and smooth muscle fibers. The latter 

 give involuntary contractility to the scrotum and 

 produce folds or rugae in the skin. (3) Intercolum- 

 nar fascia, which is a thin connective-tissue layer 

 closely associated with (4) .the cremasteric fascia. 

 The latter is continuous with the internal oblique 

 muscle. (5) The infundibuliform fascia comes next 

 and is a continuation downward of the fascia trans- 

 versalis. (6) The tunica vaginalis envelops each
