Elevated FSH level not a result of recent miscarriage
Sunday, November 23rd, 2008Hi Dr. Lee,
Your website is great! I would very much appreciate your advice, please.
Here is the background:
- At age 39, my new husband and I got pregnant on our first try. A beautiful Honeymoon Baby!
- Six months ago (I was 41 1/2), we became pregnant again without any medical intervention. We had tried for 6 months and finally “hit it” when someone gave us a tip about ovulation predictor kits.
- Sadly, I miscarried at 7 weeks. My period returned 4 weeks later.
- Now I am 42 and am seeking fertility help. Upon reviewing my diagnostic tests, I was surprised to find out my FSH levels were 28 and I only had 5 total eggs visible in my ovaries. This seems difficult to reconcile with the relative ease to which I’ve been able to get pregnant.
My question: My FSH test was taken 4 months after the miscarriage. Could the elevated levels and low egg reserve be due to my body still recovering from the miscarriage? I would greatly appreciate any insight you may have, as I can’t find any research about the impact of miscarriage on FSH levels and egg reserve.
Thank you so much!
Joanne
Dear Joanne,
An FSH level of 28 is not unusual at age 42. First of all, if it was not done on or near day #3 of your period, there is a chance it could be inaccurate. If it was done on the correct date, then it is an unfavorable sign. However, as long as you are still having regular menses, there is still a glimmer of hope. Every RE has their own “war story” of a patient with a high FSH who went on to have a baby. I can recall a patient who had a FSH of 27 who went on to have a healthy baby with her own eggs. The bottom line is that your age together with your FSH put you in a category of women who have a low possibility of spontaneous pregnancy, but while low, it is not entirely zero.
Now to address your question directly, the fact that you had a miscarriage just four months prior to that unfavorable blood test means that you still had the capability to get pregnant. The miscarriage itself would NOT be expected to affect the validity of the test. If anything, there might be a scenario where a recent miscarriage causes a falsely OPTIMISTIC result. Meanwhile, you would be wise to just enjoy loving your precious “honeymoon baby”, while you and your husband continue to get together randomly every 2-3 days. In my opinion, IVF would not really boost your chances enough in relation to how much it costs, but you could always discuss it further with your own RE or OB. Good luck!
