Fig 1. Of 156 patients with reciprocal or Robertsonian translocations who received genetic counseling, 67 chose natural conception and 15 were excluded from the study.

The remaining 89 chose PGD and 15 were excluded from the study. All comparisons were performed between the 37 patients of the PGD group who were ≤34 years old and the 52 patients who conceived naturally so that the patients who underwent PGD could be matched for age. The subsequent outcomes of the 126 patients were ascertained from the medical records and by telephone until July 2014.
