Arms Assigned Interventions
No Intervention: A
Embryo selection for transfer based on a Day 3 score only.
Drug: Human derived FSH
Customized for each patient
Other Name: Bravelle
Active Comparator: B
Embryos for transfer by first selecting any embryos that had a positive sHLA-G expression of OD = 190 ±6 and correlating such with the highest GES score available.
Drug: Human derived FSH
Customized for each patient
Other Name: Bravelle

Detailed Description:

Comparing pregnancy rates and implantation rates when embryos are selected using the most common criteria for embryo selection on day 3 - the morphology-(number of blastomere, their shape and size and the percentage of fragmentation)vs a graduated embryo score accumulated over 72 hours and the expression of sHLA-G at 44-46 hours post fertilization.
