part of part of duct epithelial cell glandular secretory epithelial cell seminal vesicle glandular cell Seminal vesicle glandular cells belong to a specialized group of epithelial cells that form the internal lining of the seminal vesicles, a pair of male reproductive organs. These cells are located within the complex tubuloalveolar glands that make up the seminal vesicles and are known for their unique pseudostratified columnar epithelium structure. The primary function of these cells is the secretion of a variety of substances that ultimately constitute around 70% of the fluid volume of semen. Seminal cells produce a high-fructose fluid that serves as an energy source for the spermatozoa and promotes their motility. They also secrete other essential substances like proteins, enzymes, vitamin C, prostaglandins, and various other compounds. Collectively, these substances help in the nourishment, protection, and transportation of the spermatozoa throughout the male reproductive system and during the ejaculation process. Secondary to the production of seminal fluid, the seminal vesicle glandular cells also play a role in the contraction of the seminal vesicles during ejaculation. The contraction of these glands, induced by sympathetic nerves, ensures the efficient propulsion of the seminal fluid mixed with spermatozoa into the ejaculatory ducts and subsequently to the urethra. Notably, any malfunction or pathological condition affecting these cells can impact male fertility, emphasizing the importance of understanding the intricate functions of seminal vesicle glandular cells in maintaining the healthy physiological function of male reproduction.
