White bumps on the testicles are commonly mistaken as a sexually transmitted disease. Most of the time it's the natural occurrence known as Fordyce's spots. Fordyce's spots are said to occur because of genetics, but the exact cause is still unknown. The typical observation would reveal small, painless white spots or nodules located on the shaft of the penis or on the scrotum. There is no treatment needed for Fordyce's spots. Another cause of small white bumps on the scrotum would be folliculitis or in lay terms, clogged hair follicles. Folliculitis can be contagious if it originates as an infection.
See a dermatologist if you are experiencing pain, itching, fever or any other unusual symptoms.
Clean the affected area with an antibacterial wash such as benzoyl peroxide twice daily to exfoliate dead skin cells and keep pores open.
Apply a topical antibiotic such as terbinafine, a cream used to treat jock itch, after each cleaning to get rid of any bacteria or fungus that may be present on the skin. You can find numerous brands in your local drugstore.
If you see no improvement in seven days or conditions worsen after this period, you may need to see a doctor.
