The tail of the epididymus connects to the vas deferens through the epididymil duct.
The epididymus attaches the testicle to the rest of the body. It can become inflamed (and this can become very painful), in a condition called epididymitis.
epididymus
They are made in the testes but are stored in the epididymus.
sperm are both matured and stored in the epididymus.
Sperm is produced in the testes and then matures in the epididymus.
The epididymis belongs to the reproductive system, specifically the male reproductive system.
The sperm complete their development in the epididymis.
The epididymis is a long tube that is located near each testicle. The epididymis is the tube which moves the sperm from the testicles to the vas deferens.
The coil duct that transports sperm is the vas deferens. It is a muscular tube that carries sperm from the epididymis to the ejaculatory duct in preparation for ejaculation.
It could be a cyst on the epididymus, or testicular torsion. But go and see your doctor to make certain what the problem is, testicular cancer is treatable but if it is left untreated it can kill.
From the epididymus, sperm travels into the vas deferens, two 18-inch tubes composed of smooth muscle and mucosa lined with cilia. (These are the structures that are cut and tied off during a vasectomy, preventing the sperm from moving any further.) The action of the smooth muscle and cilia move the sperm up around the bladder into two ejaculatory ducts, where they will mix with fluid from a seminal vesicle
