...When I say that an AMH level of below 1 means "sub fertile" to REs/fertility doctors, that is their own standard of trying to figure out who will respond best to ovarian stimulation for IVF. Lord knows on this board alone, we've seen many women succeed--with IVF, IUI, and even TTC au naturale--with AMH levels below 1. So, despite what any pre-IVF testing may suggest, one can, indeed, beat the odds despite test numbers that may make you cry when you see them.
...When I say that my own AMH of .65 is "not encouraging," that just means that many REs would not view me as an ideal candidate for IVF, and would not encourage me to try cycling with my own eggs. But then again, I'm over 44, so no RE would see me as an ideal candidate, regardless of my AMH!
In short, we've seen many success stories from women on these boards who have high FSH, low AMH, luteal phase defects, and all sorts of so-called hormonal challenges. Take your test results with a grain of salt, find a good, high-FSH and/or low-AMH friendly RE, and keep the faith.
