Scrotal or testicular pain may be acute or chronic and may or may not be associated with swelling: Epididymo-orchitis is a relatively common condition usually due to infection (either associated with urinary infection or sexually-transmitted disease). It causes acute or subacute pain and swelling of the epididymis and may present as a tender scrotal mass. Ultrasound can exclude testicular cancer as a cause and can confirm the diagnosis by localising the swelling to the epididymis and often showing increased vascularity.Torsion of the testis presents with acute onset pain in a child or adolescent. It is often severe, and if not treated expeditiously can lead to death (loss) of the testicle. Ultrasound with Doppler studies can confirm the diagnosis, and exclude differentials including torsion of the appendices of the testis and epididymo-orchitis.
Reproduction, development and work

This is a coiled tubular organ arising from the upper back part of the testes. Its function is to provide storage for immature sperm. While in the epididymis sperm mature to become fully functional. With sexual stimulation the walls of the epididymis contract to expel sperm into the ductus deferens.

Male reproductive system is responsible for production, storage and transport of sperm under hormonal control. The sperm and testosterone hormone are produced in two testes protected in the scrotal sac. The sperm pass from the testis to the epididymis where the storage of sperm occurs. Just before ejaculation, the sperm pass from the epididymis to the vas deferens. The vas deferens joins the ejaculatory duct from the seminal vesicle. At time of ejaculation, the sperm mix with the seminal fluid produced by seminal vesicle and prostate to produce semen which passes out of the body through urethral meatus [14].
