Abstract

OBJECTIVE:

To determine if the addition of continuous morphokinetic data improves reproductive outcomes when all embryos are cultured in a closed system.

DESIGN:

Prospective, randomized, controlled study.

SETTING:

Single academic center.

PATIENT(S):

A total of 235 patients undergoing fresh autologous IVF cycles with at least four embryos, cultured in the Embryoscope: 116 patients randomized to conventional once-daily morphologic embryo screening (CS) and 119 to additional time-lapse kinetic monitoring (TLM) for selection.

INTERVENTION(S):

TLM versus CS.

MAIN OUTCOME MEASURE(S):

Intrauterine clinical pregnancy (CPR) and implantation (IR) rates.

RESULT(S):

CPR and IR were similar overall (TLM vs. CS, respectively: CPR 68% vs. 63%; IR 51% vs. 45%) and with blastocyst transfers (CPR 74% vs. 67%; IR 56% vs. 51%). CPR with day 5 transfer was threefold higher than day 3 transfer, but group (TLM vs. CS) was not a significant predictor of clinical pregnancy or implantation. Significantly more multinucleation was detected when CS embryos were retrospectively reviewed with the use of TLM (7.0% vs. 35.3%), and multinucleation was independently associated with decreased rates of implantation. Time to the start of blastulation of <100 hours after insemination and the morphokinetic scoring system used in the TLM group were independently associated with implantation.

CONCLUSION(S):

The addition of time-lapse morphokinetic data did not significantly improve clinical reproductive outcomes in all patients and in those with blastocyst transfers. Absence of multinucleation, timing of blastulation, and morphokinetic score were found to be associated with blastocyst implantation rates.
