TESE (TEsticular Sperm Ekstraction)
TESE/testis biopsy/testis mapping are procedures performed for men who have testis failure. The procedure is performed to see if there are sperm present as well as for pathologic diagnosis to evaluate for malignancy. It is either done as a scheduled procedure or is coordinated with their female partner’s egg retrieval. TESE is usually performed in the operating room with sedation, but can be performed in the office with local anesthesia alone.. Patients usually cryopreserve sperm during this procedure for future IVF/ICSI. This diagnostic biopsy is usually performed to evaluate for an obstructive etiology – microdissection TESE has replaced this as the optimal form of retrieval for testis failure patients.
