Results: Thirty-eight preimplantation genetic diagnosis cycles involving 17 couples were completed. A
total of 450 (82.6%) of the total oocytes were MII oocytes, and 158 (60.0%) of the two-pronuclei embryos
were biopsied. In 41.4% of the fluorescent in situ hybridization analyses, the results were either normal or
balanced. Embryos were transferred back after 21 cycles. Three babies were born from Robertsonian
translocation carriers and another two from reciprocal translocation carriers. The miscarriage rate was
0%. Among the reciprocal translocation group, the live delivery rate was 8.3% per ovum pick-up cycle and
18.2% per embryo transfer cycle. Among the Robertsonian translocation group, the live delivery rate was
14.3% per ovum pick-up cycle and 20.0% per embryo transfer cycle
