Are there any side effects of vasectomy?

I haven't specifically looked into vasectomy, I just heard stories related to vasectomy that are posted on the internet.

Pain levels during surgery vary from person to person

It seems that everyone's feelings after surgery are different.

Since I am older, I need to consider accident prevention measures.

Since condoms are not 100% effective, I think vasectomy might be a slightly safer option.

However, I can't help but worry about the side effects.

What are the possible side effects that can occur after a vasectomy?
