Does anyone know how much weight affects IVF success rates? I've seen some pretty shocking statistics but I'm hoping that these statistics might be also moderated by how healthy you are generally.

I'm big but I'm muscly and exercise 4-5 times per week... I'm still obese but somewhat healthy...

I'm also wondering if the F.S. will refuse to do IVF until I lose the weight? That is my big fear... has this happened to anyone out there brave enough to admit it?

TIA
