Testicular diseases can be classified as endocrine disorders or as a disorders of the reproductive system. The testicles are well-known to be very sensitive to impact and injury. Blue balls is a slang term for a temporary fluid congestion in the testicles and prostate region caused by prolonged sexual arousal. The most prominent diseases of testicles are: 1  testicular cancer and other neoplasms. 2  swelling of a testicle, caused by hydrocele testis.  inflammation of the testicles, called orchitis.
Another cause of non-testicular scrotal pain is an inguinal hernia, which is when part of the intestine protrudes down through the abdominal wall into the scrotum. A varicocele, or abnormally dilated vein in the scrotum, can cause a similar type of dull ache.A dull ache originating from the testicle itself could be due to a benign mass such as a cyst, or more rarely, due to a more serious condition such as testicular cancer.ften, when men present with pain in the scrotum, the pain is not actually originating from the testicles, but rather from the surrounding structures. One such cause is epididymitis; this is inflammation of the epididymis, a coiled group of tubules sitting on top of the testicles.
