LAYERS OF SEMINAL
VESICLE
Mucosa
Muscularis
Adventitia
 Epithelium
lined by
tall nonciliated
columnar cells &
short round basal
cells
 Columnar cells have
morphology of
protein secreting
cells with well
developed rRER &
large secretory
vacuoles in the apical
cytoplasm
 Secretion
contains
fructose, along with
simple sugars, amino
acids, ascorbic acid &
prostaglandins
 Secretory function &
morphology of
seminal vesicles are
under the control of
testosterone
