IVF using Frozen Thawed Eggs

Being an early eggfreezer using the fast freezing vitrification technique pioneered at McGill University, circa 2008, I was blessed with 25 eggs, via 3 IVF egg freezing cycles, plus 4 more eggs from a fourth using the slow freezing at another clinic.  According the McGill statistics, pregnancy rates based on IVF using fresh eggs vs frozen thawed eggs are comparable.   McGill university produced the first baby born from in Canada frozen thawed eggs in 2005, so with those goals in mind, I decided to return to McGill for IVF treatment to start a family with my fiance.

The IVF process using previously frozen (and then thawed) eggs includes the following steps within a 3-6 week duration:
1-Staring Estrogen medication,2-3 weeks, used to simultaneously prevent follicular growth and the build the uterus lining
2-Ensuring Uterus Lining Ready to Accept Embryo Implantation,
3-Starting Progesterone inject able medication,  7-10 days
4-Thawing all available eggs, fertilizing with sperm, to create Embryos, concurrently while taking Progesterone
5-Growing Embryos for 2 to 5 days
6- Tranfering Embryos into the Uterus
7-Freezing remaining Embyros for next Transfer

During our consultation end of October with Dr Dahan, it was discussed that transporting embryos to New Jersey or Detroit for genetic testing could hurt the embryos.  Since 99% of abnormal embryos will stop development, through a miscarriage, a Panorama bloodtest in Week 10 was suggested to test genetics in the fetal cells.  The test will hopefully reflect a healthy fetus and the pregnancy continues full term to produce a healthy baby girl or boy!
