A scrotum ultrasound (testicular ultrasound) is a painless, noninvasive imaging test using high-frequency sound waves to produce images of the testes and surrounding tissues. It evaluates lumps, pain, swelling, infections, torsion, varicocele, hydrocele and blood flow using Doppler. Performed by a sonographer, it takes 10–30 minutes and helps diagnose causes of acute or chronic scrotal symptoms without radiation.

Yes. Scrotal (testicular) ultrasound is a safe, non‑invasive test using sound waves rather than radiation. It’s widely used to evaluate pain, swelling, lumps or infertility, usually painless with only minor probe pressure. No known long‑term harms; suitable for adults, children, and pregnant patients. The only common limitation is avoiding placement over severe open skin infections.

A scrotal scan (testicular ultrasound) is generally painless and non‑invasive. A warm gel is applied and a small probe moved gently over the scrotum; you might feel mild pressure or brief discomfort, especially if the area is tender or inflamed. The exam is quick, uses no radiation, and usually needs no anesthesia. If a biopsy or aspiration is required, local anesthesia is given and more discomfort may occur.

Normal scrotal ultrasound shows testes with homogeneous, medium‑level echotexture and smooth margins, symmetric in size and position. Tunica albuginea and epididymis appear intact with no focal lesions. Color Doppler demonstrates normal, symmetric blood flow. No hydrocele, mass, calcification, or dilated pampiniform plexus (varicocele) is seen; scrotal wall is thin without abnormal thickening.

Yes. Sexually transmitted infections can affect the scrotum — causing pain, swelling, lumps, redness, ulcers or tender testes/epididymis. Chlamydia and gonorrhea may cause epididymitis; herpes and syphilis can produce sores or nodules; HPV can cause warts. Prompt testing and treatment are important to prevent complications; avoid sexual contact until cleared and seek medical evaluation for scrotal pain, swelling, or lesions.

No — routine scrotal ultrasound generally does not require shaving. The sonographer will apply gel to the skin and excess pubic hair rarely prevents adequate imaging. If hair is very dense and interferes, staff may ask you to trim the area; follow any site-specific instructions. Avoid powders, lotions, or oils before the exam and wear loose clothing or bring underwear to change into.
