Location: at the superior end of the testis and proximal portion of the epididimis
Function: connection the rete testis to the epididimis, reabsorption of the fluid secreted in the seminiferous tubules
Composition: highly convoluted ducts are lined with pseudostratified columnar epithelium that contains clumps of tall cells with cilia and short cells on basal lamina. Among these cells are a few basal cells and intraepithelial lymphocytes. Fibromuscular layer consists of smooth muscle cells and elastic fibers.
Location: along the posterior surface of the testis
Function: sperm maturation during their passage, acquiring motility and ability to fertilize an egg.
Composition: highly coiled tube is lined by
Function: absorption of fluid, phagocytosis, and secretion of glycerophosphocholine, sialic acid and glycoproteins, possibly steroids.
Function: rhythmic peristaltic contractions serve to move the sperm
Location: it ascends and enters abdomen, then descends to the pelvis and connects to the prostatic urethra. The distal part, ampulla, joins with the duct of the seminal vesicle and continues through the prostate as the ejaculatory duct.
Location: inside the prostate gland
