Freezing Your Lab

The aim of assisted reproductive treatments is live birth of a healthy baby as fast as possible in the most effective and ef-ficient way. Freeze all strategy has been proposed as an option not only for preventing OHSS but also increasing live birth rates.There are no clinical data supporting the widespread use of the freeze-all strategy for all IVF patients at the moment. Based on available RCTs, it seems reasonable to implement this strategy in patients at risk of OHSS and when perform - ing PGT-A at the blastocyst stage. All other potential indi - cations, (repeated implantation failure, high progesterone levels on the trigger day, advanced maternal age and endo-metriosis) still need to be explored in well performed large RCTs.
