Better Outcomes with Fresh or Frozen Transfers?
In a randomized controlled trial (RCT) at a private fertility center, researchers found basic parity in outcomes between fresh and frozen transfers.1
Fresh or frozen transfers. Conducting the study between January 2014 and October 2015, the researchers randomized 179 patients on the day of hCG administration to either a fresh transfer (88 women) or a frozen thawed transfer (91 women).
Dead heat. In this study, implantation and ongoing clinical pregnancy rates were virtually the same for fresh and frozen transfers. Therefore, to make future recommendations, the researchers suggest comparing other benefits of each type of transfer, such as affordability, speed, and ease of scheduling, as well as incidence of low birth weight and preterm births.
