Abstract:
OBJECTIVETo study whether the rates of pregnancy and implantation decline in repeated IVF/ICSI cycles and whether the decline is associated with the availability of embryo cryopreservation.
METHODSWe retrospectively analyzed the pregnancy and implantation rates of 1,033 IVF/ICSI cycles accomplished in our center to determine the association of the clinical outcomes with the availability of embryo cryopreservation.
RESULTSThe rates of pregnancy and implantation declined slightly in the cycles with embryo cryopreservation (43% vs 43%, P > 0.05; 29% vs 24% , P > 0.05), but significantly in the repeated IVF/ICSI cycles without embryo cryopreservation (43% vs 35%, 43% vs 22% , P < 0.05; 29% vs 23% , 29% vs 16% , P < 0.05).
CONCLUSIONThe rates of pregnancy and implantation remain similar in the following cycles for those with embryo cryopreservation in the first IVF/ICSI cycles, but decline significantly in the repeated IVF/ICSI cycles for those without.
