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]
A hydrocele is an accumulation of serous fluid in a body cavity.A hydrocele testis, the most common form of hydrocele, is the accumulation of fluids around a testicle.It is often caused by fluid collecting within a layer wrapped around the testicle, called the tunica vaginalis, which is derived from peritoneum.
However, as the fluid continues to accumulate and the scrotum further enlarges, more discomfort can be expected. Large hydroceles will cause discomfort because of their size. Sometimes pain can be in both testicles as pressure from the enlarged area puts pressure against the unaffected area which can cause discomfort to the normal testicle.
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 ...

There are three main theories as to the anatomical cause; the first has to do with the geometry of the veins, wherein the vein on the left side connects to the larger outflowing vein at a right angle, which tends to fail; the second is that testicular valves that are supposed to prevent backflow fail (venous insufficiency) leading to swelling ...
[4] [2] In males, the phenomenon results in an uncomfortable testicular sensation. [5] It most often describes a temporary fluid congestion in the testicles or vulva, caused by prolonged sexual arousal without orgasm. [6] [7] The term epididymal hypertension is derived from the epididymis, a part of the male reproductive system. [8]
Symptoms of orchitis are similar to those of testicular torsion. These can include: [citation needed] hematospermia (blood in the semen) hematuria (blood in the urine) severe pain; visible swelling of a testicle or testicles and often the inguinal lymph nodes on the affected side.
