NCT02302638

Brief Summary

This prospective study with sibling oocytes will evaluate the efficiency of two commercial single-step media, namely Sage 1-step and Continuous Single Culture Medium (CSCM), in terms of embryo utilization rates, blastocyst formation rates, embryo quality and pregnancy rates. Embryos will be cultured continuously for up to 6 days under identical conditions.

Outcome Measures

Primary Outcomes (2)

  • Utilization rates

    Utilization = embryos selected for transfer and cryopreservation

    6 days post oocyte retrieval

  • Blastocyst formation

    Number of blastocysts on day 5 post oocyte retrieval per fertilized oocytes

    5 days post oocyte retrieval

Secondary Outcomes (4)

  • Embryo quality on day 3

    3 days post oocyte retrieval

  • blastocyst quality on day 5

    5 days post oocyte retrieval

  • positive pregnancy test

    15 days post oocyte retrieval

  • clinical pregnancy

    7 weeks of gestation

Study Arms (2)

Sage 1-step

ACTIVE COMPARATOR

Embryo culture in different single-step media: Half of each patient's oocytes will be randomly allocated to be cultured in Sage 1-step medium for up to six days following oocyte retrieval.

Other: embryo culture in different single-step media

CSCM

ACTIVE COMPARATOR

Embryo culture in different single-step media: Half of each patient's oocytes will be randomly allocated to be cultured in CSC medium for up to six days following oocyte retrieval.

Other: embryo culture in different single-step media

Interventions

Half of each patient's oocytes will be randomly allocated to be cultured either in Sage 1-step medium (Origio) or in CSC medium (Irvine Scientific) for up to six days following oocyte retrieval.
