The differential diagnosis of testicular pain is broad and involves conditions from benign to life-threatening. The most common causes of pain in children presenting to the emergency room are testicular torsion (16%), torsion of a testicular appendage (46%), and epididymitis (35%). [4] In adults, the most common cause is epididymitis. [citation ...
The vas deferens (pl.: vasa deferentia), ductus deferens (pl.: ductūs deferentes), or sperm duct is part of the male reproductive system of many vertebrates. In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens.
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 ...
Sperm can linger in the vas deferens, and it can take about 15 ejaculations to clear it out (or a couple of months). He urges patients to get a semen analysis after two or three months to make ...
Elevation of the testicle may worsen the pain. Urinary symptoms, such as pain or increased frequency of urination are also typically absent. [7] Symptom onset often follows physical activity or trauma to the testes or scrotum. Children with testicular torsion may awaken with testicular or abdominal pain in the middle of the night or in the ...
7: Deferent duct (ductus deferens or vas deferens) Prehn's sign (named after urologist Douglas T. Prehn) [1] is a medical diagnostic indicator that was once believed to help determine whether the presenting testicular pain is caused by acute epididymitis or from testicular torsion. [2]
Adult human testicle with epididymis: A. Head of epididymis, B. Body of epididymis, C. Tail of epididymis, and D. Vas deferens. Those aged 15 to 35 are most commonly affected. [2] The acute form usually develops over the course of several days, with pain and swelling frequently in only one testis, which will hang low in the scrotum. [3]
Chronic testicular pain is long-term pain of the testes. [ 2 ] [ 3 ] It is considered chronic if it has persisted for more than three months. [ 1 ] Chronic testicular pain may be caused by injury , infection , surgery , cancer , varicocele , or testicular torsion , and is a possible complication after vasectomy . [ 2 ]
