I would have to say yes. I know many BB ladies who have had laps done as a routine and endo (and other issues) have been found. I am one of them. I had stage three endo and adhesions and fibroids and the only real symptom i had was infertility! We still needed IVF/ICSI due to DH, but at least I gave our cycles a better chance with the endo etc removed.
It's a pretty minor procedure really. It's not much fun, it's actually not too bad in terms of pain etc. And the cost if IVF is so much, that if you can rule anything out with a lap, then I think it's worth it. It will provide you with peace of mind.
