Cryopreservation is a set of revolutionary technologies in the field of cryobiology. Cells and tissues can be successfully frozen at extremely low temperatures that allow virtually stopping of biological process of aging and cell death, and more importantly, then, after a period of several years to several decades, could be unfrozen successfully while retaining its full functionality.

Decades of scientific discoveries, and development of specific freezing substances that help cells to survive this process, so-called cryoprotectants, as well as specific freezing mechanisms on the basis of slow freezing method used earlier, and vitrification method used nowadays, have contributed a successful freezing and later thawing with huge survival rate of almost all human cells, including those most vulnerable – egg cells.

The survival rate of egg cells by advanced methods of vitrification has reached a staggering 95% or even more nowadays, even though few years ago were only 20%.

The fact that almost 40% of children born after In Vitro Fertilization procedures, started their life as an embryo which was frozen at fertilization and subsequently thawed by cryopreservation methods, speaks in favor of safety of the procedure. That demonstrates the efficiency and safety of the Procedure, since in these situations even a lower rate of complications in pregnancy is recorded.

Today cryopreservation is successfully applied to almost all types of human cells by routinely freezing sperm, egg cells, embryos, and the tissue around the testicles and ovaries in certain indications.
