    Small pimples on the testicles may be related to sebaceous cysts, folliculitis, genital warts, epididymal cysts, testicular tumors, etc., which can be treated by local cleaning, drug application, surgical excision, etc. It is recommended to seek medical treatment promptly for a clear diagnosis to avoid delaying the condition.

    1. Sebaceous cyst

    Blockage of sebaceous glands may lead to the formation of cysts, which appear as painless indurations. Usually small in size and slow growing, with a smooth and movable surface. Excessive cleaning or improper squeezing may induce infection. If no symptoms can be observed, erythromycin ointment or mupirocin ointment should be used according to the doctor's advice when combined with infection, and surgical excision should be performed if necessary.

    2. Folliculitis

    Bacterial infection of hair follicles can cause localized redness and swelling, which may be accompanied by pain or pus. It is easily induced by a humid and hot environment in the private parts, and is common when hygienic conditions are poor or immunity is low. You can use iodophor to disinfect and then apply fusidic acid cream to keep the affected area dry and breathable. Repeated attacks require investigation of underlying diseases such as diabetes.

    3. Genital warts

    Human papillomavirus infection causes cauliflower-like growths that are contagious through contact. Initially, there are single or multiple tiny protrusions, which gradually merge into a mass. Cryotherapy is required to remove warts, and imiquimod cream is used to suppress the virus. Sexual partners need to be examined and treated simultaneously, and sexual intercourse is prohibited during treatment.

    4. Epididymal cyst

    Cystic tumors that appear in the epididymis are soft and fluctuating to the touch. It may be related to local duct obstruction or inflammatory stimulation, and most of them are asymptomatic. B-ultrasound examination can confirm the diagnosis. If the diameter exceeds 2 cm or causes discomfort, surgical removal can be considered. Daily pressure on the scrotum should be avoided.

    5. Testicular tumors

    Abnormal proliferation of testicular tissue forms a hard mass, which may be painless and easily ignored in the early stages. Malignant tumors grow quickly and have irregular surfaces, often accompanied by a sinking feeling in the testicles. The diagnosis needs to be confirmed through tumor marker detection and imaging examination. Radical orchiectomy is the main treatment method, followed by radiotherapy and chemotherapy according to the pathological type.

    You should choose loose cotton underwear for daily use to reduce friction and avoid prolonged sitting in high temperature environments. Use your fingers to gently examine the surface of the testicles while taking a bath. If you find new growths or existing pimples that have enlarged and hardened, seek medical attention immediately. It is forbidden to prick or squeeze the pimple by yourself. During the treatment, keep a light diet, quit smoking and limit alcohol consumption to promote recovery. Regular review is crucial to determine the effectiveness of treatment and changes in condition.
