OBJECTIVE: To determine if preimplantation genetic diagnosis (PGD) for translocation carriers with three or more pregnancy losses reduces loss rates. DESIGN: Retrospective review of data. SETTING: Preimplantation genetic diagnosis laboratory servicing IVF groups. PATIENT(S): Patients (n = 192) undergoing PGD for either a reciprocal translocation or Robertsonian translocation who had three or more previous pregnancy losses. INTERVENTION(S): Preimplantation genetic diagnosis for translocations. MAIN OUTCOME MEASURE(S): Pregnancy loss rate, pregnancy success rate defined as delivery of at least one child or an ongoing pregnancy in the third trimester, and length of time to success. RESULT(S): Pregnancy loss rate was significantly reduced to 13% post-PGD compared with 88.5% in previous non-PGD pregnancies and to 35% to 64% from naturally conceived pregnancies as reported in the literature. Pregnancy success rate was 87%. Conception occurred after an average of 1.4 cycles or
