Has anyone had laparoscopic surgery when no symptoms of endo are present?

We've been ttc for 21 months. I've had the hsg, and my husband has gone for the sa. All came back fine. My doctor has started me on clomid and also suggested laproscopic surgery to check for endo. Has anyone else had this? I have had zero symptoms and have very regular cycles, and I ovulate every month. Just not sure I want to go ahead with surgery when it might be for nothing! Any insight would be appreciated.
