Can a vasectomy cause a hydrocele?

A vasectomy itself does not directly cause a hydrocele, but it can lead to conditions that may contribute to hydrocele development. A hydrocele is a fluid-filled sac around the testicle, often resulting from injury, inflammation, or infection. If a vasectomy leads to complications such as swelling or infection, this could theoretically increase the risk of developing a hydrocele. However, hydroceles can occur independently of any surgical procedure.
