Ejaculatory duct obstruction (EDO) is a pathological condition which is characterized by the obstruction of one or both ejaculatory ducts. Thus, the efflux of (most constituents of) semen is not possible. It can be congenital or acquired. It is a cause of male infertility and/or pelvic pain.
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 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]
A narrowed ureter may lead to ureteric enlargement and cause swelling of the kidneys (hydronephrosis). [13] Associated symptoms may include recurrent infections, pain or blood in the urine; and when tested, kidney function might be seen to decrease. [13] These are considered situations when surgery is needed. [13]
The treatment depends on the cause. Medications may work for retrograde ejaculation but only in a few cases. Surgery rarely is the first option for retrograde ejaculation and the results have proven to be inconsistent. [11] Medications do not help retrograde ejaculation if there has been permanent damage to the prostate or the testes from ...
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.
Vas deferens are less commonly palpated during routine a physical examination, hence the absence may go unnoticed. Also, injury to Vas deferens common in surgery. [1] Vas deferens may be absent on one or both sides, and in whole or in part. When only a part of Vas deferens is absent, it may fail to establish communication with the epididymis. [2]
A diagram of the mechanism of action of vas-occlusive contraceptive methods. Vas-occlusive contraception is a form of male contraception that blocks sperm transport in the vas deferens, the tubes that carry sperm from the epididymis to the ejaculatory ducts.
