For some, these monthly commentaries may provide interested observers with the intended overview of what the particular issue of JARG delivers to our readership, often couched within current topics in reproductive medicine and biology that would not be evident in the conventional journals covering these fields of endeavor. For others, the stretch of the imagination afforded by editorial prerogative and cogitation of the associative variety leads more directly to head scratching-not a bad thing in this altered world of disorder we now live in. Whatever your response, that climate change above and beyond our well-worn concerns over ocean salinity and temperature, deforestation, and environmental contamination are here to stay, the same conclusion we must accept when it comes to the COVID-19 pandemic. So we at JARG continue to offer a perspective that sometimes will follow well within the purview of reproductive medicine and biology, but will at times appear to stray off limits all to induce a level of curiosity, disgust, and maybe even enlightenment when it comes to facing the challenges of the day in this strange year of 2020. Such is the case with the latest and greatest scientific reports (should really say summaries) ranging appropriately from how SARS-CoV-2 is playing some novel and neverbefore-witnessed games with the cell biological management of pathogenic viruses [1] to treating the current pandemic as a catalyst for understanding its impact on the future fertility of our species [2]. Next month’s issue of JARG will take these widely divergent aspects of COVID-19 to our readership through the lens of living with the pandemic today and in the not-so-distant future relative to what will happen over the long term given the already disturbing reality of broad based and lingering health deficits known to affect many survivors of the disease. Closer to home, and the climate within which ARTs are practiced today, the overarching question has been and will * David F. Albertini [email protected] 1

continue to be selecting high quality embryos for transfer that have the best chance of producing healthy offspring. Getting from retrieved oocyte to blastocyst has created a standard of care driven historically by achieving as many retrievable follicles after an appropriate controlled ovarian stimulation (COS) regime with an attitude of “the-more-the-merrier” for stockpiling frozen embryos. That attrition during extended culture due to developmental arrest, iatrogenic elimination as poor “test-takers” (read aneuploid for example), or embryos lacking the wear-with-all to recover from cryopreservation is how we operate and only sets the stage for repeat cycles, at least for those patients lucky enough to respond well to COS. But knowing all embryos start this journey as ovarian oocytes, has increas
