What is pruritus scroti?
Pruritus scroti is a common condition characterized by scrotal itching (the skin sac containing the testicles). The condition may occur due to infections, systemic inflammatory disorders, worm infestations, allergies, and tumors. The crotch is warm and moist, which is prone to fungal and bacterial infections and rashes. Also, jock itch (also called tinea cruris), scrotal eczema, allergic reactions, and sexually transmitted infections (STI) are common causes of scrotal itching in many men.
Scrotal itching can be associated with itching in other parts of the body and other systemic signs and symptoms. Laboratory investigations, bacterial and fungal culture, skin biopsy, etc., may be required to diagnose the cause. Treatment involves treating the cause, symptomatic relief, and lifestyle modifications.

What are treatments for pruritus scroti?
Treatment options include the following:
