Could blood clotting disorder affect IVF success?

Dear Professor Winston,

Many thanks for running this seminar.

I would be interested to know if you are aware of any evidence to suggest that having a diagnosis or, and being treated for, a blood clotting disorder (specifically anti-thrombin III deficiency, treated while undergoing IVF with high levels of Clexan) negatively impacts the chances of successful implantation and full-term pregnancy. I have experienced two early miscarriages and three failed implantations.

Many thanks,
