Of the 17 studies that have described the use of FSE [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 32 , 33 , 34 , 35 , 36 , 39 , 41 ], nine studies required a benign FSE to perform TSS [ 22 , 23 , 26 , 28 , 29 , 32 , 33 , 34 , 39 ]. Eight studies incorporated the technical feasibility in the considerations of a testis sparing approach [ 22 , 26 , 28 , 29 , 32 , 33 , 34 , 39 ].…”
