Preimplantation genetic diagnosis (PGD) is an attractive addition to prenat
al genetic diagnosis. Not only were traditional PGD indications valid. but
newer indications should be envisioned. The major new indication is aneuplo
idy testing by PGD for transfer of euploid embryos. This could increase fer
tilization success in ART, and extend to couples experiencing repeated IVF
failures or repeated spontaneous abortions. Other novel indications can be
envisioned for the future. (C) 2001 Elsevier Science Ireland Ltd. All right
