What typically causes hydrocele in older boys and adult men?

Hydrocele in older boys and adult men commonly occurs due to infection or injury. When the scrotum becomes inflamed or subjected to trauma, fluid can accumulate in the tunica vaginalis, which is the pouch of tissue surrounding the testicle. This accumulation of fluid leads to the formation of a hydrocele. Conditions such as epididymitis, orchitis, or trauma to the scrotum can disrupt the normal balance of fluid production and absorption, resulting in a hydrocele. It is important to differentiate these underlying causes from other factors such as genetic predisposition or hormonal changes, which are less commonly associated with this condition in the specified age groups.
