Kawwass JF, et al. - Researchers sought to describe national outcomes of oocyte thaw (OT) cycles via this retrospective descriptive study. They identified 54,675 oocyte cryopreservation (OC) and 6,413 OT cycles reported to the Society of Assisted Reproductive Technology Clinic Outcome Reporting System from 2012 to 2018. Increase in the absolute numbers was noted from 2,719 to 13,824 and from 348 to 1,810, respectively. Among reported OT cycles, a decrease in the rates of pregnancy and live birth was observed as age at the time of cryopreservation (ATOC) increased. A significant increase was noted in the number of oocytes thawed to achieve one live birth with increasing age ATOC. Further, there was a decrease in the rate of good perinatal outcome as age ATOC increased among the resulting pregnancies.
