A Testicle Lump Should Not Be Confused with the EpididymisThe epididymis can be mistaken for a small testicle lump. The epididymis is a tube-like structure that joins the testicle with the vas deferens. You can find the the epididymis along the back of each testicle. It is soft and can be sometimes more sensitive than other parts of the testicle or scrotum, but never painful.
The epididymis can become swollen and inflamed, causing a lump to appear. This condition is called epididymitis and is often a complication of gonorrhea and chlamydia in young men and adults. Lumps caused by epididymitis often cause panic because men often correlate a lump with testicular cancer.
