What causes pimples on the testicles?

Acne-like bumps on the testicles may be caused by various factors, mainly including folliculitis, eczema, and orchitis. Folliculitis is an inflammation caused by bacterial infection of the hair follicles and may manifest as red pimples similar to acne on the testicles. In severe cases, these bumps may increase in size and be accompanied by symptoms such as itching and prickling. Eczema may be triggered by multiple factors, such as moisture and allergies, and can also cause acne-like bumps on the testicles, accompanied by pain and swelling. Orchitis is an inflammation of the testicles caused by bacterial infection, leading to redness and swelling of the scrotum on the affected side, pimples on the testicle, and significant tenderness. For these conditions, it is recommended to seek timely medical attention and undergo targeted treatment based on a doctor's diagnosis. Additionally, personal hygiene should be maintained in daily life, keeping the testicles and surrounding areas clean and dry to prevent bacterial growth. Regarding diet, spicy and greasy foods should be avoided as much as possible, and more fresh vegetables and fruits should be consumed to help improve skin condition.
