Ultrasound imaging of the scrotum uses sound waves to produce pictures of a man’s testicles and surrounding tissues. Your doctor may also refer to this ultrasound as a testicular sonogram or scrotal ultrasound. It is the primary method used to help evaluate disorders of the testicles, epididymis (a tube immediately next to a testicle that collects sperm) and scrotum.

This study is typically used to:

– Determine whether a mass in the scrotum felt by the -patient or doctor is cystic or solid and its location.

– Diagnose results of trauma to the scrotal area.

– Diagnose causes of testicular pain or swelling such as inflammation or torsion.

– Evaluate the cause of infertility such as varicocele.

– Look for the location of undescended testis.

Typically, there’s no special preparation necessary for a testicular ultrasound. There’s no need for dietary restrictions, fasting, or a full bladder before the exam.
