Oogenesis: female gamete formation; occurs in the ovaries. Passes through the inguinal canal into the pelvic cavity. Courses over superior aspect of the urinary bladder. Each duct merges with a vas deferens to form the ejaculatory duct. = slightly lower than body temperature (requirement for producing viable sperm) Provides a site for immature sperm entering it from the testis to complete their maturation process. Transports sperm from the epididymis to the ejaculatory duct. Alkaline secretion that contains fructose and citric acid to nourish the sperm. Neutralizes traces of acidic urine in urethra prior to. Connective tissue shealth that runs along the ductus deferens containing nerves and blood vessels. Serves as a copulatory organ and birth canal.
