How do I prepare for a testicle biopsy?

Your healthcare provider will talk to you about how to prepare for the procedure. You may be told not to eat or drink anything after midnight on the day of your procedure. Your provider will tell you which medicines to take or not take on the day of your procedure.

What will happen during a testicle biopsy?

  • You may be given local anesthesia to numb the area. With local anesthesia, you may still feel pressure or pushing, but you should not feel pain. You may instead be given general anesthesia to keep you asleep and free from pain during the procedure. Your provider may insert a needle into your testicle. The needle is attached to a syringe. Cells or sperm are drawn into the syringe. The needle will then be removed and the skin covered with a bandage.
  • Your provider may do an open biopsy. A small incision will be made on the skin that covers the testicles. Your provider may make another incision in the testicle and take a sample of tissue through the incision. Sometimes a groin incision is made to get to the testicle. Your provider will close the incisions with stitches and cover the area with a bandage. The sample taken will be sent to a lab for tests.

What are the risks of a testicle biopsy?

You may be sore in the area where the biopsy was done. You may bleed more than expected or get an infection. Your testicle may need to be removed.
