What causes a small pimple on the testicles?

The appearance of small bumps on the testicles may be related to a variety of factors. Common causes include folliculitis, sebaceous cysts, genital warts, epididymitis or testicular tumors. It is recommended to seek medical treatment promptly for a clear diagnosis and avoid self-treatment.

1. Folliculitis

Folliculitis is an inflammation caused by a bacterial infection around the hair follicles that appears as red papules or pustules. It may be related to poor local hygiene, excessive sweating or friction from clothing. You can use topical antibiotics such as mupirocin ointment and fusidic acid cream as directed by your doctor, and keep the affected area clean and dry.

2.Sebaceous cyst

Obstruction of the sebaceous ducts leads to accumulation of secretions to form cysts, which are palpated as round subcutaneous nodules. If secondary infection occurs, redness, swelling and pain may occur. Smaller cysts do not require treatment, but larger ones can be removed surgically. Avoid squeezing to prevent worsening of infection.

3. Genital warts

Sexually transmitted diseases caused by HPV infection, manifesting as cauliflower-like growths. Warts need to be removed through cryotherapy, laser surgery, or medications such as topical podophyllotoxin tincture. After diagnosis, sexual contact should be avoided and partners should be notified for joint screening.

4. Epididymitis

Bacterial infections of the epididymis are often accompanied by painful swelling of the testicles and may be caused by a urinary tract infection or sexually transmitted disease. Oral antibiotic treatment such as levofloxacin tablets and cefixime dispersible tablets is required. In the acute stage, the patient should rest in bed and hold the scrotum elevated.

5. Testicular tumors

Painless lumps should alert you to the possibility of testicular cancer, which may be accompanied by a feeling of swelling or changes in testicular texture. Ultrasound examination and tumor marker detection are required to confirm the diagnosis. Treatment is mainly surgical resection, combined with radiotherapy and chemotherapy when necessary. Early detection has a better prognosis.

In daily life, you should choose breathable cotton underwear to avoid prolonged sitting and local high temperature environment. Gently clean the scrotal skin during bathing. If you find abnormal swelling, ulceration, or symptoms such as fever, you must seek medical attention immediately.
