Hi Sherm, sounds like you need to chat with your FS at SIVF as soon as possible, the FS is the best person to explain why high FSH levels are bad. My understanding of it is that as a woman's ovarian reserve (eggs) diminishes the brain senses this and sends heaps of FSH to the ovaries to kick them into action to retain fertility as long as possible. So it is a sign of the ovaries winding down and heading towards menopause. This is hereditary, some women will be ovulating into their late 40's others have premature menopause (there is a lady on this site who had menopause at age 30, I believe).

But I have also read that one high FSH reading does not necessarily indicate that it's all doom and gloom, it is possible that having that test another cycle may give a different result.

I hope your FS gives you all the info you need, reassures you and outlines your options. Good luck
