A non-invasive Doppler ultrasound of the scrotum uses sound waves to produce pictures of a male's testicles and surrounding tissues. The test determines the disorders of the testicles, epididymis (tubes immediately next to the testicles that collect sperm), and scrotum. The test is safe, non-invasive, and does not use ionizing radiation.

A scrotal Doppler test is recommended if you are experiencing any of the following symptoms:

  • Pain or discomfort in the scrotum
  • Swelling or lumps in the scrotum
  • Infertility
  • Abnormalities in the shape or size of the testicles
What happens during Scrotal Doppler Test?

A high-frequency sound waves are used to produce high-quality images of the blood flow in the scrotum. The test measures the velocity and direction of blood flow in the veins and arteries that supply blood to the testicles. It can be used to evaluate the functioning of testicles and to diagnose any issues that may be affecting blood flow. 

Furthermore, scrotal Doppler ultrasound measures the size and shape of the testicles. This test can be helpful in cases of testicular torsion because blood flow to the twisted testicle may be reduced. Also, it can indicate the development of conditions such as testicular cancer, varicocele, and hydrocele.
