This is *the* question that gets discussed so much on the message boards. “What’s the highest FSH you’ve ever heard of?” We all want to see how far away we are from the “normal” range. It’s a question 99.9% of RE’s absolutely will not answer – they skirt around it or they indicate that an FSH of 15.1 (one tenth above their cutoff) is an absolutely dire situation (it’s serious, but not necessarily dire).
So, how high is too high? The reason why this question is so difficult to answer is that every case is different – comparing fertility between two women based on an FSH reading is highly arbitrary – there are so many other factors at play that it almost makes the question meaningless. And still we ask it, and so I think the question deserves some consideration.
Dr. Jerome Check is mentioned on my Where Can I Find a Doctor page as being high-fsh-friendly. Additionally, he has, over the years, been very active in performing clinical studies and writing up case studies and submitting them to the medical establishment. So, rather than relying on informal statistics, it is best to answer based on clinical evidence. This study documents several women getting pregnant with FSH levels ranging from 21 to 41. This is a pretty common range for women who are diagnosed with ‘high FSH’. Here is a study documenting pregnancies with an FSH of 127 and 143. And this fairly recent study documents a successful pregnancy in a woman with an FSH of 164.
So, I’m not in any way trying to tell you that it’s commonplace for women with high FSH to get pregnant. These studies do, however, provide some perspective on the question “how high is too high”. The point is not to fill anybody with false hope, and these cases – particularly triple-digit FSH – are highly unusual but the point is that it’s *possible*.
