Histology
Histologically, the seminal vesicles are notable for their tortuous pathways, diverticula, pseudo-stratified columnar epithelium and cuboidal cells along the basal layer.
The height of these columnar cells, and therefore activity, is dependent upon testosterone levels in the blood.
The lumen is large and stores the fluid secretions (but not spermatozoa) between ejaculations.
From inside to out, the layers are:
- Mucosa - arranged into convoluted folds, significantly increasing surface area
- Muscular - well-developed layer composed of an inner circular and outer longitudinal layer of smooth muscle
- Connective tissue
