Design outcomes

Primary

MeasureTime frame
Determination of typical characteristics of previously planned (elective) and unplanned freeze-all procedures after stimulation with Bemfola®, with a specific focus on non-elective freeze-all procedures as a response to the risk of ovarian hyperstimulation syndrome (OHSS)

Secondary

MeasureTime frame
Analysis of frequency, indications, burdens and results of the freeze-all procedure Assessment of the medicinal endometrial preparation (priming) when transferring cryopreserved embryos Obtaining data from the daily practice (real-world data) on further treatment parameters for fertilization, cryopreservation, embryo development, luteal phase support, as well as implantation and pregnancy rates Description of the tolerability profile of Bemfola®, including the incidence of Ovarian Hyperstimulation Syndrome (OHSS) and other adverse drug reactions (ADRs)
