Calcinosis on the scrotum, otherwise known as scrotal calcinosis or calcinosis scroti, is a benign medical condition where deposits of calcium appear on the outside of the scrotum in the form of nodules or lesions. Nodules are typically purple, yellow, or white in color. Additionally, nodules can grow in both quantity and size over time, ranging from a few millimeters to multiple centimeters in diameter as they gradually coalesce.

Many patients wait years before seeking the advice of a medical professional, as the nodules rarely cause physical pain. (Although itchiness or a “heavy” feeling are possible.) Nodules are usually not attached to any underlying structures and are not a result of high levels of calcium or phosphate in the bloodstream.

In fact, there is still some debate in the medical community over what causes calcinosis on the scrotum, though it may be linked to genetic predisposition and/or tissue breakdown during aging or trauma. But what is crystal clear is the emotional trauma that men with this condition deal with, as these unflattering bumps and lesions can significantly hamper their self-esteem and wreak havoc on their sex life.
