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.
Ejaculatory duct obstruction is the underlying cause for 1–5% of male infertility. [8] Since ejaculatory duct obstruction is a relatively rare cause of infertility, this possibility may be unfamiliar to some physicians, even some urologists.
Ejaculatory duct obstruction is an acquired or congenital pathological condition in which one or both ejaculatory ducts are obstructed. [9] In the case that both ejaculatory ducts are obstructed, this illness presents with the symptoms of aspermia and male infertility. [9] [10]
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower ...
In vasectomies, the vas deferens are cut and the two ends are tied to prevent sperm from passing. Sperm granuloma may then grow at the point where the vas deferens were cut. [2] This could happen two to three weeks post procedure. Sperm granuloma can also form from sperm leaking from the vas deferens into the surrounding interstitium.
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 .
From here, in males, they cross under the vas deferens and in front of the seminal vesicles to enter the bladder near the trigone. [2] In females, the ureters pass behind the ovaries and then travel in the lower midline section of the broad ligament of the uterus. For a short part, the uterine arteries travel on top for a short (2.5 cm (1 in ...
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 ...
