The seminal vesicles secrete a significant proportion of the fluid that ultimately becomes semen. [10] Fluid is secreted from the ejaculatory ducts of the vesicles into the vas deferens, where it becomes part of semen. This then passes through the urethra, where it is ejaculated during a male sexual response. [9]
The end of the epididymis is connected to the vas deferens. The vas deferens ends with an opening into the ejaculatory duct at a point where the duct of the seminal vesicle also joins the ejaculatory duct. [1] The vas deferens is a partially coiled tube which exits the abdominal cavity through the inguinal canal.
The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...

Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. [2] They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus. [3]
Vessels surrounding the vas deferens, some of the vessels in the seminal vesicle, and a vessel from the posterior surface of the prostate drain into the external iliac lymph nodes. [4] Some of the seminal vesicle vessels, prostatic vessels, and vessels from the anterior prostate drain into internal iliac lymph nodes. [4]
In a male, they develop into a system of connected organs between the efferent ducts of the testis and the prostate, namely the epididymis, the vas deferens, and the seminal vesicle. The prostate forms from the urogenital sinus and the efferent ducts form from the mesonephric tubules .
The inferior vesical artery is distributed to the trigone and inferior portion of the urinary bladder, the ureter, prostate, vas deferens, and seminal vesicles.vas deferens. The branches to the prostate communicate with the corresponding contralateral vessels. [3]
