Natural Versus Artificial Cycle for Frozen-Thawed Embryo Transfer — NAFT  

Embryo Transfer Clinical Trial

Official title:
Frozen-thawed Embryo Transfer in a Natural Versus Artificial Cycle: a Randomized Clinical Trial

Clinical Trial Summary

This study evaluates clinical pregnancy rates, obstetrical outcome parameters, costs and patient preferences in natural cycle versus artificial cycle frozen embryo transfers (FET).

Clinical Trial Description

Transfer of cryopreserved embryos can be performed in a natural cycle (NC-FET) or in an artificially prepared cycle (AC-FET). Both cycle regimens have their advantages and disadvantages. So far, most comparative studies have failed to identify the optimal protocol for FET. In this study patients undergoing FET will be randomized between an endometrial preparation by a natural cycle or by an artificial cycle (by oestradiol validate and micronized progesterone). ;
