The seminal vesicles are extraprostatic structures located posteriolaterally to the prostate near the base of the prostate. They are glandular structures each comprised of a singular tube repeatedly folded on itself. The seminal vesicles have a thick muscular layer surrounding the luminal mucosa that is utilized for production and excretion of seminal fluid. During ejaculation, seminal fluid is pushed through the seminal vesicle lumen where it meets the ipsilateral vas deferens to form the ejaculatory ducts at the prostate. The seminal fluid moves through the ejaculatory duct as it passes through the prostate, mixes with prostatic fluid, and enters the prostatic urethra at the verumontanum where it is ultimately ejaculated as semen.
Reproduction, development and work
Published in Chris Winder, Neill Stacey, Occupational Toxicology, 2004
The seminal vesicles produce seminal fluid that constitutes 60% of the volume of semen. It is very rich in fructose (a sugar) which nourishes the sperm after it has been deposited in the female reproductive tract. The duct from the seminal vesicles and the ductus deferens join to form the ejaculatory duct, so that sperm and seminal fluid enter the urethra together during ejaculation.

Male reproductive system is responsible for production, storage and transport of sperm under hormonal control. The sperm and testosterone hormone are produced in two testes protected in the scrotal sac. The sperm pass from the testis to the epididymis where the storage of sperm occurs. Just before ejaculation, the sperm pass from the epididymis to the vas deferens. The vas deferens joins the ejaculatory duct from the seminal vesicle. At time of ejaculation, the sperm mix with the seminal fluid produced by seminal vesicle and prostate to produce semen which passes out of the body through urethral meatus [14].
