There are many reasons for examining the scrotum with ultrasound. These are among the more common reasons:
Ultrasound might not provide all the information your doctor requires. In those cases, additional studies could be required.
No preparation is necessary.
There is no pain involved in an ultrasound examination of your scrotum. The transducer is placed on the skin surface after a gel is applied to your scrotum to provide better contact. The gel can feel cool and could temporarily leave a mark on your clothes, so you might want to wear easily washable clothing.
The scrotal ultrasound examination takes about 15 minutes but can take longer in more difficult examinations.
