[Vasectomy and prostatic cancer]

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.
