The ejaculatory duct is a short tubule located just above the prostate gland. It is formed by the connection of the vas deferens and the seminal vesicles, and serves to transport spermatozoa through the prostate gland and into the urethra.
 Research Ejaculatory Duct
The epididymides are narrow, elongated storage vessels for newly generated spermatozoa. They are located within the scrotum, adjoining each testicle. Spermatozoa remain in the cord-like
epididymides until ejaculation, at which time they eject them into the vas deferens.
Research Epididymides
The male reproductive system is responsible for generating, storing, and transporting the genetic material contained in the sperm cells, or spermatozoa. The chief organs include the testicles (or testes), the epididymides, the vas deferens, the ejaculatory duct, the urethra, and the penis. Auxiliary organs include the bulbourethral (Cowper's) glands, the prostate gland, and the seminal vesicles. Spermatozoa (sperm cells) contain the chromosomes which will combine with those of the ovum, or egg (produced by the female reproductive system), to form the embryo of a new human. These spermatozoa are generated within the testicles and stored within the epididymides. During sexual arousal, a fluid created by the seminal vesicles and the prostate gland combines with the sperm cells to create semen, which is carried through the urethra and out of the opening, or meatus, in the end of the erect penis. When the semen is deposited in the female vagina, the spermatozoa swim through the uterus to the fallopian tube, where one, or more, may fertilize an
egg, or ovum.
Research Male Reproductive System
The seminal vesicles are responsible for secreting a fluid component of semen as the sperm cells pass through the vas deferens. The two vesicles resemble small, bulbous pouches and are located just above the prostate gland.
Research Seminal Vesicles
The spermatic cords are the intermediary pathways beginning with the vas deferens and joining to form the ejaculatory duct. Nerves, arteries, veins, and lymphatic glands join the vas deferens to compose these cords.
Research Spermatic Cords
Vasectomy is the surgical sterilisation of a man by cutting, and tieing the vas deferens in the testicles. It has been reported that the only noticeable difference after a vasectomy is a milder flavour of the ejaculate.
Research Vasectomy
The vas deferens is the narrow continuation of the canal of the epididymis, serving to transport the sperm cells from the epididymis, up through the inguinal canal toward the bladder, and then to the spermatic cords and the ejaculatory duct.
