Percutaneous Testicular Biopsy (TESA)

Percutaneous Testicular Biopsy (TESA)

Percutaneous testicular biopsy, or TESA, is performed by a puncture with a special needle attached to a syringe. Therefore, no incision is necessary.

This type of biopsy is less aggressive than TESE, but less sperm is obtained.
