FI = fascial interposition, LE = ligation and excision, EC = electrocautery, TC = thermal cautery a restricted to the two centers in the cautery study that had information about motility. b includes all centers in the cautery study. c n/N (%) = the number of men with the outcome of interest (semen analysis with any motile sperm or with 1 × 106 sperm/mL or more) divided by the total number of men who provided a semen sample for a given vasectomy technique and early recanalization status for that time period. |
