ABSTRACT
Nevertheless, even in cases of OA, testicular sperm extraction (TESE) may be preferred over FNA whenever cryopreservation is an option and motile epididymal sperm has not been obtained. If testicular aspiration is performed with a needle of a larger diameter, tissue cylinders may be obtained facilitating cryopreservation (14). Unfortunately, these alternative methods are less patient-friendly than fine-needle aspiration and require locoregional anesthesia.
