Testicular biopsy is performed in one of two methods – a percutaneous method or an open method. In a percutaneous method, the surgeon will use a thin needle to extract a tissue sample from the testicle without the need for any incision or stitches. For an open procedure, the surgeon will make a small incision into the skin of the testicle to remove a small tissue sample.
In most cases, the procedure is an outpatient one, and the procedure can be completed in a single day. Patients are required to abstain from sexual activity for 7-10 days after the procedure.
