Cross-section and glandular epithelium of the seminal vesicle
The seminal vesicle, a pair of glands behind the urinary bladder, is an inner male reproductive organ. It's excretory ducts lead into the upper (prostatic) part of the urethra, each with one seminal duct. It´s secretion is alkaline, fructose-rich, and part of the seminal fluid, which increases the sperm's motility and neutralizes the acid vaginal flora. The glandular epithelium consists of simple squamous as well as multi-row columnar epithelium. The connective tissue (myoelastic stroma), as well as organ's capsule, contains many smooth muscle cells.
