EPIDIDY

The epididymis extends longitudinally at the posterior edge of the testis.

It has a superior dilation that goes beyond the superior pole of the testis, which is called the head; an intermediate following which is the body and inferiorly a narrower portion which is the tail of the epididymis.

At the head of the epididymis, the efferent ducts of the testicles continue for again very tortuous ducts which then successively anastomose to form a single tube which is the duct of the epididymis.

This duct is so winding that it occupies a space of approximately two centimeters in length, when in reality it is six meters long.

Inferiorly, the tail of the epididymis, having the epididymis duct inside, bends sharply back and up, following the deferent duct.

It is precisely in this curve constituted by the tail of the epididymis and beginning of the vas deferens that sperm are stored until the moment of sexual intercourse, when they are taken abroad.

The first portion of the vas deferens is more or less winding and ascends immediately behind the epididymis.

Both the testis, the epididymis, and the first portion of the vas deferens are directly surrounded by a serous membrane that is the vaginal tunic.

Like the pleura or pericardium, the vaginal tunic has a leaflet that directly surrounds those organs, being called the visceral lamina.

Subsequent to the aforementioned organs, the visceral lamina of the vaginal tunic is reflected from each side to continue with the vaginal lamina.

Between the visceral lamina and the parietal lamina of the vaginal tunic, there remains a virtual space called the vaginal cavity.

The vaginal cavity contains a small amount of fluid that facilitates sliding between the two blades.
