During follow-up, participants completed a questionnaire asking whether they had experienced new pain in their eyes, hands, or testicles; those who experienced pain were asked to indicate on which side of the body the pain occurred (left or right). The pain questionnaire was completed by 290 of 351 male donors (83%) and 97 of 126 male nondonors (77%) a median of 3 years after baseline (interquartile range = 2-6).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Inverse probability of treatment weighting on a propensity score was used to balance donors and nondonors on baseline characteristics.

In the weighted analysis, the risk of testicular pain was significantly greater among donors than nondonors: 51\/290 (17.6%) vs 7\/295 (2.3%); weighted risk ratio, 7.8 (95% confidence interval [CI] = 2.7 to 22.8). Donors and nondonors did not differ statistically in terms of self-reported eye pain or hand pain. Among donors, the occurrence of testicular pain was most often unilateral (92.2%) and on the same side as the nephrectomy (90.2%). Testicular pain occurred more often in donors who had laparoscopic vs open surgery: 48\/246 (19.5%) vs 3\/44 (6.8%) but was similar in those who had a left-sided vs right-sided nephrectomy: 44\/253
