The testis (fig. 223) in the horse weighs approximately about 8 ounces. It is oval in shape, with somewhat flattened sides, and hangs suspended by the spermatic cord in the scrotum. The testicle is a gland made up of a number of tortuous tubes enclosed in a somewhat thick, dense, fibrous capsule. A long narrow body termed the epididymis runs along the outer part of the upper border; this is not a part of the testicle proper, but an appendage to it, and consists of the excretory ducts of the organ thrown into a number of closely-united coils. The anterior extremity of this body is large and rounded, and is called the " globus major" (g, fig. 223). The ducts of which it is composed are continuous with those of the testicle. The posterior extremity, much smaller than the anterior, is the "globus minor" (b, fig. 223); from it springs the "vas deferens", or chief excretory duct of the gland.
