Summary

This monocenter academic study aims to evaluate the effectiveness and cost effectiveness of two different strategies: fresh Embryo Transfer (ET) on day 3 followed by cryopreservation of cleavage-stage (Day 3) embryos versus blastocyst-stage (Day 5) embryos.

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.
