Twenty men undergoing vasectomies completed the Tennessee Self Concept Scale shortly before the operation and again at 6- and 18-month postoperative follow-up periods. Twenty nonvasectomy comparison subjects completed the test at the same points in time. Results indicated that vasectomy adversely affects psychological adjustment, and this effect fluctuates over time as a function of preoperative level of defensiveness. In contrast, vasectomy was not found to effect changes in self-concept.
20名接受输精管切除术的男性在手术前不久完成了田纳西自我概念量表测试，术后6个月和18个月的随访期又再次进行了测试。20名未接受输精管切除术的对照受试者在相同时间点完成了该测试。结果表明，输精管切除术对心理调适有不利影响，且这种影响会随着时间的推移根据术前防御水平而波动。相比之下，未发现输精管切除术会导致自我概念的变化。
