A tube in the male reproductive system that passes from the epididymis into the abdominal cavity the seminal vesicles vasa efferentia.
The two tubes by which sperm leave the epididymis (the “holding area” behind each of the two testes where the sperm mature) to mix with semen and to be released through the ejaculatory duct in orgasm. It is the vas deferens that are cut during vasectomy, a surgical form of sterilization performed on males.
Either of a pair of ducts that is the extension of the epididymis of the testis, ascending into the abdominal cavity, where it passes over the bladder and joins the seminal vesicle.
In males, a narrow, coiled tube that carries sperm from the epididymis (a connecting duct) and testicles through the prostate gland and into the urethra during ejaculation. The vas deferens, about 2 feet long, is also known as the spermatic cord.
Either of a pair of ducts that conduct spermatozoa from the epididymis to the urethra on ejaculation. It has a thick muscular wall the contraction of which assists in ejaculation.
The narrow tube that leads from each testis through the prostate gland to join a tube from the seminal vesicles to form the ejaculatory duct. Sperm and seminal fluid pass through this duct during ejaculation.
The secretory duct of the testis, a continuation of the epididymis. This slim, muscular tube, approx. 18 in (45.7 cm) long, transports the sperm from each testis to the ejaculatory duct, which empties into the prostatic urethra.
The conduit responsible for storing sperm and transporting it from the epididymis to the ejaculatory duct.
Each tube in a pair that transports sperm from the testes to the urethra—the channel that carries both sperm and urine out of the body through the penis—is known as a vas deferens. The plural term is vasa deferentia.
