Hi there, I'm posting on behalf of a friend as shes having a tough time with getting pregnant and has had two op's now to remove the endo and a cyst in her ovary and is now on the zoladex injection for 3 months. She is a little anxious to come on the forums so I said I'd do it for her. She wants to know why the endo keeps coming back and whether anyone else has experienced this? She's had two ops now to remove it and it grew back substantially the last time. She has had a 6cm cyst removed from her ovary and is now on a zoladex injection. She wants to know if anyone has had a similar experience and fallen pregnant afterwards? She has been referred for IVF because she's been trying for 2 years but I think it would just reassure her to know people have been through the same thing and been successful. Many thanks in advance!
