epididymal cyst

Epididymal cyst (found in the vessels attached to the testes)

It is commonly associated with epididymal abnormalities, such as spermatocele, epididymal cyst, and epididymitis.

Male defects have included epididymal cysts, agenesis of the vas deferens, or infertility due to abnormal spermatozoa.

There are many other conditions, such as testicular microlithiasis, epididymal cysts, and appendix testis (hydatid of Morgagni), which may be painful but are non-cancerous.

The U.S. Centers for Disease Control (CDC) has acknowledged the link between diethylstilbestrol exposure and noncancerous epididymal cysts.

Men exposed to DES before birth (in the womb), known as DES Sons, are at an increased risk for non-cancerous epididymal cysts.

These problems range from harmless abnormalities like the recurring development of epididymal cysts - benign growths that feel like small lumps on the back of the testicles - to the far more serious possibility of an increased risk of testicular cancer.
