Testicular biopsy
Testicular biopsy is a procedure in which a small portion of testicle is removed for examination. The biopsy is performed by creating a small incision in the skin of the scrotum. A small piece of the testicle tissue is removed through the incision by snipping the sample off with small scissors. The test is usually performed when a semen analysis suggests that there is abnormal sperm, and other tests have not determined the cause. It may also be performed when testicular self-examination has revealed a lump.
