Predictive value of pregnancy during original in vitro fertilization cycle on implantation and pregnancy in subsequent cryothaw cycles.

Journal Article (Journal Article)

OBJECTIVE: To understand the homogeneity of oocyte quality within a cohort. DESIGN: All women (n = 367) that had cryopreserved pre-embryos subsequently thawed were studied. Pregnancy and implantation rates in the in vitro fertilization (IVF) and cryothaw transfers were examined. SETTING: Tertiary care academic center. RESULTS: Pregnancy in original IVF cycle predicted higher implantation rates at subsequent cryothaw transfers. Similarly, pregnancy in cryothaw cycles was associated with higher implantation and ongoing pregnancy rates at the initial IVF cycle. CONCLUSIONS: Within a cohort of oocytes, pregnancy with some of the pre-embryos in a cohort predicts pregnancy with the remaining oocytes in the cohort. Thus, oocytes within a cohort have similar pregnancy potential.
