I had endometriosis when i was in my 20s and a cyst removed near the ovaries. Despite all that and my age, i managed to have a baby without trying more than a few months . I had my baby at 37 and had never tried previous to that to conceive. So don't give up hope, a friend of mine had an ovary removed and still conceived.
Good luck!

I have had endo for 15yrs, I had a cyst removed that covered 3/4 of my ovary and two seperate ops for the endo.  I don't know about pituitary microadenoma, but I do know that endo does not mean you will not be able to have children.  I first went on hormones for the endo for about 6 mths but then went to a naturapath and had years of accupunture to help with the pain and to keep it under control.  I have since had 3 healthy children and my endo has not yet returned.  Have you spoken to your dr about your concerns??  It is good to get as much info as you can especially if your endo is mild or severe.  if you havn't spoken to him I really suggest you do.  If you need anymore help or info please don't hesitate to email me
