There are two ways in which this procedure can be performed: Diagnostic and therapeutic. Under the diagnostic method, biopsies are performed to check whether sperms are being produced in the testes or not. In case of absence of sperms, the diagnosis of a total testicular failure is confirmed and treatment options are accordingly chalked out. In most such cases, treatment options include either adoption or donor insemination as no other viable option is available. In case sperms are found, the testicular system can be cryopreserved for future treatment. The procedure is less expensive but in several cases, patient is required to repeat the test if they are willing to use their sperms for intracytoplasmic sperm injection (ICSI). In therapeutic method, which is most of the times recommended by the doctors, sperms which are found can be immediately used for ICSI.
