Cryo IVF refers to the use of cryopreservation within the IVF treatment pathway – most commonly frozen embryo transfer, in which embryos cryopreserved from a previous stimulation cycle are thawed and transferred in a subsequent cycle. It also encompasses sperm cryopreservation prior to IVF treatment, donor egg and donor sperm programmes, and fertility preservation cycles for patients facing medical treatment that may compromise future fertility. Each of these applications requires a distinct set of cryogenic equipment and protocols. Frozen embryo transfer requires validated vitrification and warming protocols, appropriate cryogenic storage, and robust sample identification and traceability systems. Sperm cryopreservation requires a controlled rate freezer running a validated protocol, cryogenic consumables for sample packaging, and storage capacity matched to the clinic’s throughput. Cryolab supplies the full range of cryo IVF equipment covering storage, freezing, transport, and consumables for all of these clinical applications.
