Cryopreservation has transformed family planning. Whether preserving surplus embryos after an IVF cycle or freezing eggs/sperm before medical treatments, modern vitrification delivers exceptional survival rates.
Vitrification is an ultra-rapid cooling technique that solidifies cells into a glass-like state without the formation of damaging intracellular ice crystals.
Freezing surplus high-grade embryos allows couples to attempt additional pregnancies in future years without having to undergo repeat ovarian stimulation and egg retrieval procedures.
Key questions to consider include the annual cryostorage maintenance fees, the clinic's liquid nitrogen monitoring protocols, and legal consents regarding embryo disposition.
