walls of the Seminal Vesicles secrete a slightly alkaline fluid, which helps to regulate the pH of the tubular contents as sperm cells are conveyed to the outside. The secretion produced by the Seminal Vesicles also contains a variety of nutrients, such as fructose (fruit sugar), that provides the sperm cells an energy source. At the time of ejaculation, the contents of the seminal vesicles are emptied into the ejaculatory ducts. This action greatly increases the volume of fluid that is discharged by the vas deferens.
