Considering the growing of vasectomy worldwide, its likely association with several conditions, mainly prostate cancer, has been studied in recent years with sometimes contradictory results. In the light of recent epidemiological studies, it appears that the increased risk derived from a previous vasectomy is limited, and it is influenced by whether the operation is performed during puberty and with a long "latency period". It is acknowledged that there is no scientifically proven reasons to appraise the current methods, although there is some insistence on the need to carry out analytical studies, most specially in developmental areas.
考虑到输精管切除术在全球范围内的增加，近年来人们对其与多种疾病（主要是前列腺癌）的可能关联进行了研究，结果有时相互矛盾。根据最近的流行病学研究，既往输精管切除术带来的风险增加似乎有限，且受手术是否在青春期进行以及“潜伏期”长短的影响。人们承认，虽然有人坚持需要进行分析研究，尤其是在发展中地区，但目前没有科学依据来评估现有方法。
