A varicocele is typically diagnosed through a combination of a physical examination by a healthcare provider and a scrotal ultrasound to confirm the presence of enlarged, dilated veins within the scrotum. While often identified during routine physical exams or fertility evaluations, definitive diagnosis relies on visualizing the retrograde blood flow using color Doppler ultrasound technology. How is a varicocele diagnosed? The diagnostic process for a varicocele usually begins with a physical examination while the patient is standing.

The diagnostic process for a varicocele usually begins with a physical examination while the patient is standing. A physician will palpate the scrotum to check for a "bag of worms" sensation, which is the classic clinical presentation of these dilated pampiniform plexus veins. To confirm the diagnosis, the doctor may ask the patient to perform a Valsalva maneuver—bearing down as if having a bowel movement—which increases intra-abdominal pressure and makes the varicocele more prominent.
While physical examination is the first step, imaging is the gold standard for confirmation and grading. The following methods are commonly utilized:
Although a varicocele is a common condition affecting approximately 15% of the adult male population, many patients experience frustration when their symptoms, such as dull aching or scrotal heaviness, are dismissed by primary care providers who are not specialists in urology. The "diagnostic odyssey" often involves multiple visits before a patient is referred to a specialist who recognizes that the physical discomfort or fertility concerns are directly linked to the venous dilation.
A urologist is the primary specialist responsible for diagnosing and managing a varicocele. If you are experiencing symptoms, it is vital to consult a urologist, preferably one with a sub-specialty in male reproductive medicine (andrology). Seeking a specialist is crucial because general practitioners may not always perform the necessary standing examination required to detect smaller, subclinical cases.
It is important to distinguish a varicocele from other scrotal conditions that can mimic its presentation. A physician must rule out:
