Darkening of the scrotum in males is commonly caused by melanin deposition or minor trauma and typically has no adverse effect on health, requiring no treatment. However, this discoloration may also occur due to nutritional imbalances—such as selective eating habits—that lead to inadequate intake of essential nutrients and vitamins. If symptoms such as scrotal pruritus (itching) and dry, flaky skin develop, they are usually attributable to a fungal infection. In such cases, topical application of PREDNISOLONE CREAM (e.g., “Pai Rui Song” cream) is recommended, along with maintaining good local hygiene and avoiding friction from undergarments.
