Abstract：
BACKGROUND: Vasectomy is one of the permanent methods of contraception; however, the risk of conception still exists. Early failure, defined as a postoperative semen analysis showing persistent motile sperm, occurs in 1 in every 250 patients. Late failure, defined as the rejoining of the severed ends of the vas deferens, occurs in 1 in every 2000 patients.
METHODS: A healthy 37-year-old British male presented to our clinic because his wife had conceived seven years after he had undergone a vasectomy. The result of his semen analysis after the vasectomy was negative, and the histopathological report confirmed that the sample contained tissue from both the left and right vas deferens. His wife conceived seven years after the procedure, and semen analysis at that time confirmed a total of 0.5 million sperm per milliliter of semen in a total semen sample of 6.3 ml. The total number of motile sperm recorded was 2.5 million.
CONCLUSIONS: This case shows that late recanalization can occur up to seven years after a vasectomy. Patients should be informed prior to the procedure that late recanalization, although rare, may still occur. Post-vasectomy paternity necessitates further counseling to ensure that the patient and the patient\'s partner fully understand the implications and options available to them.

摘要：
背景：输精管结扎术是一种永久性的避孕方法；然而，受孕的风险仍然存在。早期失败,定义为术后精液分析显示持续活动的精子，每250例患者中有1例发生。晚期失败,定义为输精管切断端的重新连接，每2000名患者中有1名发生。
方法：一位37岁健康的英国男性出现在我们的诊所，因为他的妻子在接受输精管切除术后7年怀孕。输精管结扎后的精液分析结果为阴性,组织病理学报告证实该样本含有来自左右输精管的组织。他的妻子在手术后七年怀孕了，当时的精液分析证实，在6.3毫升的总精液样本中，每毫升精液总共有50万个精子。记录的活动精子总数为250万。
结论：本病例显示，输精管结扎术后7年内可发生晚期再通。手术前应告知患者晚期再通，虽然罕见，仍然可能发生。输精管切除术后的亲子关系需要进一步的咨询，以确保患者和患者的伴侣充分了解他们的影响和选择。
