Functional Structure and Ultrastructure of Seminal Vesicles

Abstract

The function of the seminal vesicles in animals and man is under androgen control. The use of a new marker of the seminal vesicle function, termed corrected fructose, demonstrates an association between serum testosterone levels and seminal corrected fructose levels. The human seminal vesicles secrete a variety of products, and there is good evidence of a close relationship between functions of the seminal vesicles and sperm motility. Some of their products of secretion, such as potassium, bicarbonate, prostaglandins, and prolactin, directly stimulate the motility of the sperm through actions at the level of the mechanisms of production of the energy necessary for the motion. Several constituents are secreted by the seminal vesicles, some of which have no specific functions.

Evaluation of the Anabolic, Aphrodisiac and Reproductive Activity of Anacyclus Pyrethrum DC in Male Rats

“…Preservation of in-vitro sperm count is an indicative that the herb contains water soluble nutritive substances that help sperms in avoiding death due to lack of energy. One the other hand the fructose content is also regulated by androgens and fructose content establishes a narrow relationship among the levels of testosterone and fructose production by the seminal vesicle [16]. Therefore, the results corroborate the hype that the plant is capable of being nominated as herbal alternative for improving sexual function.…”

Possible Protective Effect of Vitamin E on Bisphenol –A Induced Changes of the Male Reproductive System of Adult Albino Rats: Histological Study.

“…The vas deferens also called ductus deferens, transport sperm from the epididymis to the ejaculatory ducts. No changes have been reported in it as also in the present finding Seminal vesicles composed of tubular alveoli and the mucosa thrown into an intricate system of folds with the epithelium overlaying the lamina propria (34), no changes were observed. Secretion of the seminal vesicles constitutes the main (50%) and the last fraction of the ejaculates.…”

Effects of Bryonia laciniosa seeds on sexual behaviour of male rats

“…Fructose synthesis is regulated by androgens and is thus directly corelated with testosterone levels. 15 The number of sperms in epididymis was also markedly increased. The increased sperm counts as well as increased fructose content are indicative of improved fertility because of extract treatment.…”

“…A calibration curve was drawn using dilutions of fructose solution and measument of the colour developed with resorcinol and HCl. 15 Hormone assay Serum concentration of testosterone (Eiagen Testosterone kit, Italy), luteinizing (LH), and follicle stimulating hormones (FSH) (Erba Fertikit, Germany) was measured following an immunoenzymatic method with an enzyme-linked immunosorbent assay reader, according to the standard protocol given in assay kit.…”
