Embryo survival after warming depends on consistent vitrification technique, high-quality media and carefully controlled handling at every step. The ESHRE 2026 study links improved survival directly to the wider move towards blastocyst culture and vitrification, alongside better incubation and reduced disturbance during culture. In practical terms, the more reliable and repeatable the process, the higher the survival rate tends to be.
Standardising protocols and using validated consumables reduces variation between operators and between cycles, which is often where survival rates slip. The straws and carriers that hold embryos during freezing also matter, because they influence cooling speed and how well the embryo is protected. Cryolab supplies clinical embryo and sperm straws and vitrification kits that support high, repeatable survival rates in day to day laboratory use.
