Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The primary outcome is the cumulative pregnancy rate after all transfers (fresh and/or frozen embryo transfer cycles which might take about 1 year), up to two sequential cycles. The secondary outcome concerns a cost analysis of both strategies from the healthcare payer's perspective.
