Objectives: To compare the pain during anesthesia and during the no-scalpel vasectomy procedure for local infiltration anesthesia (LIA), LIA supplemented with spermatic cord block (LIA + SCB), and no needle jet anesthesia. Methods: Bilateral no-scalpel vasectomy was performed in 323 patients during 2007. Of the 323 patients, 65 received LIA, 29 received LIA + SCB, and 227 received anesthesia using the no-needle technique with the MadaJet device. The level of pain during anesthesia administration and the subsequent procedural pain was documented for each technique using a pain scale of 0-10. Results: Pain during the LIA + SCB procedure (mean 1.7 ± 1.6) was significantly less than the pain during LIA (mean 3.3 ± 2.3; P <.01). No statistically significant difference was found between the levels of pain experienced during LIA + SCB and no-needle jet anesthesia (P >> .01 and P >> .05, respectively). Intraoperative pain after LIA + SCB (mean 0.64 ± 1.2) was significantly less than the intraoperative pain after LIA (mean 2.7 ± 2.6; P
