An ultrasound of the scrotum examines the testicles, epididymis and surrounding structures to evaluate pain, swelling, lumps or trauma. It identifies conditions such as testicular torsion, epididymo‑orchitis, hydrocele, varicocele and tumors, assesses blood flow with Doppler, and helps investigate infertility or guide procedures like aspiration or biopsy. It’s non‑invasive, quick, and aids diagnosis and treatment planning.

Yes. Scrotal ultrasound is a safe, non‑invasive imaging test that uses sound waves, not ionizing radiation. It’s routinely used to assess pain, lumps, infection, trauma and fertility concerns. It causes minimal discomfort; rare effects include temporary skin irritation or tenderness from probe pressure or gel. There are no known long‑term harms when used as clinically indicated.

A high-frequency scrotal (testicular) ultrasound with color Doppler is the best first-line scan for the testes. It gives detailed images of testicular structure, detects masses and fluid, and assesses blood flow—essential for distinguishing torsion from infection. MRI is used if ultrasound is inconclusive; CT is rarely used except for staging metastatic disease.

Yes—scrotal ultrasound with color Doppler is the preferred imaging test to detect scrotal infections (epididymitis, orchitis) and complications like hydrocele or abscess. It shows enlarged, inflamed tissues and increased blood flow, helping distinguish infection from torsion. Ultrasound cannot identify the causative organism, so clinical assessment and laboratory tests are still needed for diagnosis and treatment planning.

Ultrasound cannot visualize individual sperm — they are microscopic. Scrotal or transrectal ultrasound can assess testes, epididymis, seminal vesicles and ejaculatory ducts, and detect structural issues (varicocele, obstruction, cysts, dilated seminal vesicles) or fluid that affect fertility. Large semen collections (e.g., in the bladder) or aggregates may be seen, but sperm themselves are not directly visible on ultrasound.

No — routine scrotal ultrasound does not require shaving. Ultrasound gel works on intact hair, and sonographers can usually obtain clear images. Very dense pubic or scrotal hair might interfere, so you may be asked to trim a small area or the clinic can remove hair if needed. Avoid lotions or powders before the scan and follow any clinic-specific instructions.
