About this study

Donor sibling oocytes will be vitrified with two commercially available devices. The first device is closed vitrification with closed storage and the second device is open vitrification with closed storage. Oocyte acceptors receive oocytes from both devices. With the increase in cooling rate generated by the open vitrification (second device), we expect to get an increase in survival rate of 10%. Besides this, embryo quality will be assessed with oocytes obtained from both devices.

Primary outcomes

  1. Survival rate

    Time frame: up to 6 days after every warming cycle

    The purpose is to assess the survival rate of donor oocytes with the two vitrification devices.

Secondary outcomes

  1. Embryo development

    Time frame: up to 6 days after every warming cycle

    The purpose is to analyse the pre-implantation development of donor oocytes vitrified with two different devices.
