What can cause chronic testicular itching after showering?

Chronic testicular itching after showering can be caused by several factors, including skin irritation from soap or shampoo, excessive moisture leading to fungal infections, or contact dermatitis from laundry detergents or fabric softeners. Allergic reactions to personal care products can also contribute to the issue. Additionally, conditions such as jock itch (tinea cruris) or eczema may exacerbate symptoms. If the itching persists, consulting a healthcare professional is advisable for proper diagnosis and treatment.
