Active Comparator: Day 3 transfer
Subjects in this arm will have two embryos transferred three days after fertilization. Embryos will be selected based on the concentration of nitric oxide metabolites in the culture medium.
Procedure: Transfer of embryos on day 3 or day 5 after fertilization.
Subjects will be allocated at random to the two arms. Group 1 will have two embryos transferred on day 3 based on nitric oxide concentration. Group 2 will have two embryos transferred on day 5 based on morphologic criteria.
Active Comparator: Day 5 transfer
Subjects will have two embryos transferred on day 5 after fertilization with selection of embryos based on morphologic criteria.
Procedure: Day 5 transfer
Subjects will have embryo transfer on day 5 after fertilization. Selection of embryos to transfer will be based on morphologic criteria.
- Percentage of subjects with viable pregnancy one month after embryo transfer [ Time Frame: 1 month ]
- Percentage of subjects with > 2 viable embryos one month after embryo transfer [ Time Frame: 1 month ]
