Vitrification is a crucial step in in vitro fertilisation (IVF), used to freeze eggs and embryos rapidly. This fast process prevents the formation of ice crystals, which can damage delicate cells and reduce their viability. To ensure safety and maintain the quality of samples, closed system vitrification kits have become the preferred choice in modern fertility clinics. The benefits of vitrification are impressive. It gives eggs and embryos a much higher chance of surviving the freezing and thawing process compared to older methods. This has led to improved success rates in IVF, with frozen eggs and embryos often working as well as fresh ones. Vitrification kits are designed to make the process straightforward and reliable, while the ability to store frozen samples for years gives people flexibility and peace of mind about their family plans.
