OBJECTIVE: To determine the prognosis of patients who were only able to obtain aneuploid embryos in their first in vitro fertilization (IVF) cycle if they attempted a second cycle.
DESIGN: Case series and retrospective cohort study.
SETTING: A single, large fertility center.
PATIENT(S): All patients who obtained only aneuploid embryos after IVF with preimplantation genetic testing for aneuploidy during the initial cycle and returned for a second cycle.
INTERVENTION(S): None.
MAIN OUTCOME MEASURE(S): The percentage of patients who obtained a euploid embryo and live birth rates in the second cycle, stratified by Society for Assisted Reproductive Technology-defined age groups, was compared with that of controls from the same period.
RESULT(S): A total of 538 patients with only aneuploid embryos in their first cycle were included. Three hundred (56%) patients obtained euploid blastocysts in the second cycle, with younger women having a higher chance of obtaining at least 1 euploid embryo (81% in women aged <35 years vs. 25% in women aged >42 years). The cumulative live birth rates were 71%, 62%, 46%, 27%, and 13% for the age groups <35, 35-37, 38-40, 41-42, and >42 years, respectively. The live birth rates per first embryo transfer were >57% across all the age groups and similar to those of the controls in the same age groups.
CONCLUSION(S): Patients who obtained only aneuploid embryos during their initial IVF cycle retained favorable prognosis in their second cycle, with outcomes comparable with the national age-based standards. Younger women and those who had more embryos available for biopsy had the highest chance of success. These women should receive age-appropriate counseling and should not be discouraged from a second IVF attempt based on the results of their first cycle.
