The laboratory at our Southern California fertility center developed the MicroSecure Vitrification egg freezing process
Vitrification is a rapid egg freezing process. In the past, IVF labs used a slow freezing process. It presented challenges and made it more difficult to successfully preserve eggs. These challenges existed because female eggs, oocytes, have a high water content.
During slow freezing, crystallization could occur. The resulting ice crystals then had the potential to damage or even fracture the egg during the thawing process. The second problem occurred during the slow freezing process when the water in the eggs expanded as it froze. This caused damage to the egg membranes.
Vitrification solved both of these problems. First, the process is extremely fast, which eliminates the threat of crystallization. Second, new cryoprotectants not only remove some of the water within the eggs, but they also protect eggs from rupture or tissue damage.
How vitrification works
Women who want to become mothers in the future may choose to freeze their healthy eggs to use for their future family. Women who need to undergo chemotherapy or cancer treatment may also opt for egg freezing to preserve their future fertility.
Whatever the reason, when a woman chooses egg freezing at our Southern California fertility center, we begin MicroSecure Vitrification by placing her eggs in a highly concentrated bath of cryoprotectants and sucrose.
Next, the eggs are placed in liquid nitrogen in which they are frozen very quickly. Studies show that eggs can be stored for up to 10 years without degrading their quality. It may be possible to store eggs for longer periods of time, but current studies have only been conducted on eggs stored for 10 years or fewer. Our Southern California fertility center offers long-term egg storage for our egg freezing patients.
More about the process at our Southern California fertility center
Our Southern California fertility center laboratory developed the MicroSecure Vitrification procedure in 2008. We perform our egg freezing process with exceptional attention to quality control, reliability, safety and security. This procedure for oocyte preservation, or egg freezing, has proven to be highly successful, yielding some of the highest pregnancy and live birth rates in the U.S.
