The concept of fast freezing or vitrification was first described more than 80 years ago by Basile J. Luyet, the so-called Father of Cryobiology (Luyet, 1937). He showed that supercooled solutions could be solidified without crystallization, forming a glass-like state. Already then, the potential of the technique and the associated challenges were in the research spotlight. Today, we’ve managed to overcome all methodological-related issues of vitrification. It has evolved into a reliable and efficient method to freeze oocytes and embryos. Vitrification is used for medically assisted reproduction and fertility preservation: the goal is to ensure the maximum survival rate with the highest level of biosafety. In this blog post, we will compare closed and open carrier devices for vitrification.
This year, the annual meeting of ASRM 2021 was back in its physical form, and we where there in-person with a great team from Vitrolife. For those of you who couldn´t attend the meeting or want to update yourself again on the interesting sessions, we have compiled this blog post, with thoughts and reflections from the Vitrolife team on some of the scientific content presented at the meeting.
