Oocyte cryopreservation is a procedure to preserve a woman's eggs .This technique is often used to delay pregnancy. When pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos. Several studies have shown that most infertility problems are due to germ cell deterioration related to aging. [1]
Later, when she is ready to become pregnant, the eggs can be thawed, fertilized, and transferred to the uterus as embryos. Since 1999, when the birth of the first baby from an embryo-derived from vitrified-warmed woman's eggs was reported by Kuleshova and co-workers in the journal of Human Reproduction, [ 25 ] this concept has been recognized ...
The reasons vary, but one crucial moment during which the eggs become unviable is when they are thawed. Ahead, women whose frozen eggs didn't survive the thawing process share their experiences ...
In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. [2] The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, [3] [8] also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI). [9]
The number of eggs it takes to get from egg to embryo to baby depends on several factors, such as the woman's age, egg quality and genetics. For example, for a 20-year-old female, it may only take ...
Since these systems do not work by exchanging ions, like traditional water softeners do, one benefit claimed for the user is the elimination of the need to add salt to the system. Such systems do not remove minerals from the water itself. Rather, they can only alter the downstream effects that the mineral-bearing water would otherwise have.

The word cryobiology is derived from the Greek words κρῧος [kryos], "cold", βίος [bios], "life", and λόγος [logos], "word". In practice, cryobiology is the study of biological material or systems at temperatures below normal. Materials or systems studied may include proteins, cells, tissues, organs, or whole organisms.
