SUMMARY. Efficiency of PGT-A have been studied in patients with previous IVF failure, recurrent pregnancy loss, idiopathic infertility and infertility due to other causes. More than 50 % of all embryos produced in four experimental and one control groups were found to be aneuploid. Aneuploidies of autosomes 15 and 18 and of both sex chromosomes were the ones most frequently observed. Most aneuploidies were detected in patients with previous IVF failure and idiopathic infertility. After selecting euploid embryos for transfer high clinical pregnancy rates were achieved in all study groups. In at least 30 % of patients in each study group IVF treatment coupled with PGT-A resulted in live birth. The highest live birth rate was observed in patients with recurrent pregnancy loss and previous IVF failure thus clearely demostrating the benefits of offering PGT-A as part of treatment for various types of infertility.
