  1. aPercentage of X- or Y-bearing sperm in the sorted sample after XSort and YSort, respectively.
  2. bXSort, YSort: Sorting to recover X-bearing sperm or Y-bearing sperm, respectively.
  3. cDetermined by fluorescence in situ hybridization (FISH). Both values significantly different from 50% p < 0.001.
  4. dDetermined by embryo biopsy/preimplantation genetic diagnosis (PGD).
  5. e♀, ♂ symbols denote female and male sex, respectively.
  6. f Determined by ultrasound, chorionic villus sampling, or amniocentesis. Includes cycles utilizing PGD.
  7. gDetermined by morphological examination at birth. Includes cycles utilizing PGD. Both values significantly different from 50% p < 0.001.
