How long does it take a woman to become infertile when having endometriosis?

I have endometriosis, and i need to know how long i can go without treatment before i become infertile. I also need to know that if i was to get either procedure done for "curing" endometriosis, as i'm sure it won't be, but would i still be able to get pregnant a few years later after receiving one or both of the treatments?
