One option available for women to preserve fertility is the egg freezing i.e. oocytes/eggs freezing through a multi-step laboratory procedure to preserve viability. Eggs can later be thawed and fertilized, and embryos implanted to achieve pregnancy.
Although, more difficult than freezing sperm, female egg have been recently found to survive well using improved cryoprotectant solutions and techniques. These new developments offer the hope of preserving fertility for a large number of cancer patients and for women wishing to delay family building by storing their eggs at a younger age.
We are proud to announce that we have had a very good experience with egg cryopreservation at Reproductive Fertility Center, with our embryologist being involved with multiple pregnancies after using cryopreserved eggs.
Although not clinically available yet, preliminary research suggests that eggs and ovarian tissue may be one of the best, if not only, source of compatible stem cells if the egg donor develops cancer or another devastating disease later in life. Eggs and tissue not used for fertility can be kept in storage for possible therapeutic use as the woman’s life progresses.
Egg Freezing Process
Eggs and ovarian tissue have been found to survive well using improved cryoprotectant solutions and techniques. These new developments offer the hope of preserving fertility for a large number of patients.
When ready to have children, one or more of the eggs is thawed. After thawing, surviving eggs are fertilized through the ICSI method. The fertilized eggs then usually develop into multi-celled embryos. Using a catheter, one or more embryos are then simply placed in the uterus, hopefully establishing a pregnancy.
In case of egg freezing after certain age, it is found that there is a great heterogeneity in the distribution and organization of cytoplasmic organelles. They also demonstrate considerable variability in membrane water permeability. Both of these characteristics can affect their viability and ‘competence’, as well as the success of the oocyte cryopreservation process. Our fertility doctor will discuss your best fertility option.
