Intratesticular block. The needle is inserted into the centre of the testis and 0.1-0.25 ml of local anaesthetic is injected per testicle (a; b [needle A]). During injection the testis will become firm. The intratesticular injection can be combined with subcutaneous incisional infiltration, which is applied bilaterally at the scrotum (b [needle B]). The higher volume is used for larger testes while the lower volume is administered in kittens (c). Images (a) and (c) courtesy of Paulo Steagall; image (b) courtesy ofYael-Shilo Benjamini
