This video provides a step-by-step narrated outline for performing a fine needle aspiration (FNA) mapping of the testis. FNA mapping is a procedure that has been utilized in men with non-obstructive azoospermia as a diagnostic procedure that detects the presence and relative quantity of sperm with spatial precision. Furthermore, upon identifying sperm via mapping, that information can then be utilized to help guide the type of surgical sperm retrieval that follows, such as a TESA, TESE, or mTESE. This diagnostic technique has the potential to help avoid high cost procedures, such as

mTESE, based on biopsy findings.
