===Epididymis===

The Epididymis provides the environment for final maturation of spermatozoa. It is here that they aquire motility and fertility. The Epididymal duct is very long, between 30-60 meters. It is divided functionally into 3 regions; the Caput (head), Corpus (body) and Cauda (tail). The caput of the epididymis is connected to the efferent ducts of the testes. The Cauda connects to the Ductus Deferens of the spermatic cord.

The Epididymis provides the environment for final maturation of spermatozoa. It is here that they aquire motility and fertility. The Epididymal duct is very long, between 72-81 meters in the horse. It is divided functionally into 3 regions; the Caput (head), Corpus (body) and Cauda (tail). The caput of the epididymis is connected to the efferent ducts of the testes. The Cauda connects to the Ductus Deferens of the spermatic cord.

Attached to the testicular capsule, receives the '''efferent ducts'''. After efferent ducts enter the head of the epididymis, they join to become the '''duct of the epididymis'''. Fluid secreted in the rete tubules of the testes is reabsorbed here and epididymal fluid is secreted. This fluid secretion is important in order to facilitate movement of the sperm through the epididymis.
