• prostate glands
• bulbourethral glands

stores (matures) for 2 to 10 days and moves sperm to the vas deferens

carries the mature sperm into the body to the ejaculatory ducts

Each vas deferens joins the duct from the adjacent seminal vesicle (one of the accessory glands) to form a short (2cm) ejaculatory duct. Each ejaculatory duct passes through the prostate gland and empties into the urethra.
