Could Your Blood Type Predict Fertility Issues?

New research presented at a recent American Society for Reproductive Medicine conference connects blood type to potential fertility issues in women.

The study looked at 560 women who were an average of 35 years old and currently receiving fertility treatments of some kind or another. Researchers collected and analyzed blood samples from this group of women, focusing on their FSH (follicle stimulating hormone) levels. 

What they found was that the magic FSH level seemed to be 10 for fertility success.  Women with FSH levels less than 10 struggled much more frequently than those with numbers higher than 10.

The interesting twist to this study however had to do with the connection of the FSH levels and blood types.  Researcher also found that women with O blood type were 2x as likely to have FSH levels higher than 10, and in turn experience infertility related issues.  It was the women with A blood type who were more likely to have FSH levels lower than 10.

After reading this study, I in no way believe that all women with O type blood will struggle to become pregnant.  Just as I also don’t believe that all women with blood type A will easily become pregnant.

What I do think this study tells us is that if you know that you have type O blood AND you are struggling to become pregnant, you should probably ask your doctor to test your FSH levels.  It is these FSH levels that are critical for a healthy pregnancy to begin. So knowing your levels will help point you in the right direction for your TTC (trying to conceive) plan!  Smile

I'm sorry, but this article contradicts itself. It says that the study showed that women with FSH levels of 10+ had a better time of getting pregnant, and those with FSH levels lower than 10 had more difficulty. Then it says that type O women had 10+ FSH levels and more infertility problems, with A type women experiencing the inverse. That contradicts what the correlation was supposed to be.
