are forced apart, and the condition called hydrocele is 

 produced. 



On the lateral side of the testicle a portion of the cavity 

 projects backwards between the testicle and the medial face 

 of the epididymis ; it is called the sinus of the epididymis 

 (Figs. T02, 105).

Testis. Each testicle invaginates the posterior wall of 

 the corresponding tunica vaginalis. It is an oval body with 

 flattened sides and it varies considerably in size, but averages 

 about 38 mm. (one and a half inches) in length, 25 mm. 

 (one inch) in antero-posterior diameter, and somewhat less 

 than that from side to side. 



It is free, except above and behind where it is connected
