I'm sorry I can't be of much help here except to send you good wishes. I will say that 15 is high, and based on what little I know of IVF, most RE's won't do IVF unless with donor eggs at that level. However, that info is only based on women I have met over the years here and their stories. I hope that it works out for you, I know how hard it is to deal with something like this. YOu might want to try this post on the fertility forum as so many there have lots of experience with IVF.
I'm not too sue either but I have recently seen a specialist and I have an amh of -1.1, but I'm 44, he said to me it would be terr if your amh was lower and your age was lower, ie under 38-40 because the he said that even though your overian reserve was low, you would have quite a few good eggs still left, so with your age you have quite a few good eggs going by what he would say, so it would just be the fsh I would be worried about, there is a lady on here that posted a high fsh and then totally changed her diet etc and it got down to 9 I think so you could maybe scroll down and see what she did to lower it
Its on the second page by hopeful1968, its about halfway down
You are only 34, you have age on your side and your FSH is not completely through the roof.. and an AMH of .5 may not be completely accurate-this test is controversial. I know of a couple of women who became pregnant and delivered healthy babies with blood work results similar to yours. I would think IVF with your own eggs is worth a try- and injectables will help with making more eggs and so on. If you were in your 40s with that bloodwork it would be harder to get PG-age is a big factor it seems. I think your RE is correct in stating it is worth a try- good luck and SSBD.
