Ovary? Or no ovary?

In 2005 I had my 2nd laparoscopy to look for endo (first one in 1999 showed none, but that doc may have been an idiot). During this surgery my doc found endo. Lots and lots of endo. So much so that he did what he could and told me that to clean it up better I would need a laparotomy (like a c-scetion but without the joys of a baby). I tried to avoid doing such an invasive surgery but 3 months later I went ahead and had it done. At that time the doc was able to clean most of it up but my left ovary was covered in it and the ovary was adhered to my colon. There was no way to "unstick" it without losing the ovary. My gyn knew how badly we wanted children so he left it. Soon after my symptoms lessened considerably and we went on our merry way, trying 4 IUIs with donor sperm. Well, those were a complete bust!! My left ovary (the "good" one) was the dominant one. Sounds good, right? Well, it would have been except my left tube is blocked. With the magic of clomid we were able to get both ovaries to work at the same time. Still useless as I did not conceive anyway.

Now that I have had Maddie my endo symptoms have returned. With a vengeance! I am going next week for my annual exam and will discuss this with my doc. I am considering another surgery, this time to not only clean up any endo but to remove the left ovary as well. There are two main reasons I want this sucker gone: 1) I have terrible, horrible, no good IBS which is worse when my endo is bad. I am thinking that since the ovary is stuck to my colon that it may be the cause of my increased IBS issues. And 2) I was unable to have a colonoscopy done a few years ago. They were unable to get the scope around the bend. I am wondering if the ovary is the cause of that as well.

My only reason to want to keep this ovary is that it is a super ovary, pooping out eggs like a fertile chicken. Nice, big, healthy looking eggs. If I give it up we may never be able to do IVF. At this time IVF is not a consideration. If we have to spend the money we will do EA again. However, if the law changes and insurance is required to cover infertility in my state will I then consider IVF? Would it be fair to Maddie to now have a biological child? Do I even want to go through a full IVF cycle if it is covered? Or will insurance (if mandated) cover embryo donation? Not so much the legal costs if there are any, but the FET?

I am really unsure of what I should do here! My endo is really taking a toll on me and I need some relief. I am horrible at taking daily meds so taking BCPs is a chore. And I was on them for 4 months and as soon as I stopped the pain was back and worse. So while BCPs keep the pain away, is it really slowing down the endo? What to do? What to do?? Any advice is greatly appreciated!
