Toronto- Frozen Embryo for Gender Determining in USA

Hi everyone,

We currently have two frozen embryos that we would like to find out the gender for. I currently have 3 boys and would LOVE a girl! My question is has anyone done gender determining on frozen embryos in the USA? What clinics have you used or recommend? I'm worried about thawing my eggs for the gender determination and then re-freezing and re-thawing. Any clinics out there have a quick turn around time?

I'm also interested in doing IVF if none of the eggs show to be girls.

Please help a newbie out!

Thank you!!
