Thanks for taking time out of your busy schedule to answer questions for this forum. I appreciate it and I know the others on this forum appreciate it as well.
I have a follow-up question on this topic. You say you have seen this in several occasions - have you found that it is related to high estradiol levels? For instance, women that have a good response may be in the 2000 - 3000 range for estradiol levels. Would this cause the inhospitable environment?
Could it also be related to an immune issue - is it possible for women who have conceived before to develop immune issues and if so, what would cause this?
