COVID-19 AND ART OUTCOMES

ABSTRACT

Objective: The ongoing COVID-19 pandemic has disrupted the normal methods of communication used by physicians and patients, as well as the standard protocols and procedures by which medical clinics operate. Pandemic related stresses may have also influenced patient’s fertility goals and/or their ovarian response. We questioned whether these changes resulted in any unanticipated effects in the treatments and outcomes of ART patients. Design: Retrospective cohort. Materials and Methods: Patients who underwent GnRH-antagonist IVF cycles from January 2020 through June 2020 at NYU Fertility Center, a period in New York City over which the COVID-19 pandemic escalated and life in the city drastically changed as a result of new social distancing measures, were separated by month of treatment and compared with patients from the corresponding month in the prior year (January 2019 through June 2019). Patient age, AMH, days gonadotropin, #oocytes retrieved, #oocytes matured, #fertilized, #blastocysts, and #euploid embryos were compared using Student’s T-test. Results: 1881 patients were compared over the parallel six-month periods. Clinic visits were markedly decreased over the months of March and April of 2020, when the pandemic was at its peak in NYC and treatments were suspended as per the ASRM pandemic guidelines. There were no differences in age, AMH, #oocytes retrieved, #mature oocytes, or #fertilized between the two years. In April of 2020 there were significantly more blastocysts per patient, as compared to April of 2019, however, in May and June of 2020 there were significantly fewer euploid embryos per patient, as compared to May and June of 2019 (see table). [Formula presented] Conclusions: In the months following the end of the COVID-19 treatment suspension, there were no apparent differences in patient characteristics or the quantitative responses to stimulation. However, there was a significant qualitative difference as expressed in the number of euploid embryos. It remains unclear if or how the pandemic is related to this difference.
