During In Vitro Fertilisation treatment, your ovaries may be induced to develop more eggs than usual which means that you may end up with more healthy fertilized eggs than you can use. Luckily, many fertility clinics will offer the choice to have the fertilized eggs frozen and stored away safely for use at a later time. Depending on the type of In Vitro Fertilisation service you have agreed to, this may be offered free of charge. It may be the situation that your treatment needs to be tabled for a while after the eggs have been gathered, for a number of reasons, so storing them would be an option worth considering.
There may be an occasion where you want to try In Vitro Impregnation again and by having your fertilized eggs already stored it can save time and trouble of producing the eggs again. It also means you don’t have to take fertility drugs that put you at risk of ovarian hyper-stimulation syndrome or OHSS and you can improve your chance of conception from one egg collection. Fertilized eggs can normally be frozen and stored away safely for up to five years, although this can occasionally be extended. There can be massive benefits in freezing and storing spare fertilized eggs, particularly if you or you partner have been diagnosed as infertile for instance, it still means that In Vitro Impregnation is feasible for more children.
In certain circumstances you may be allowed to store your frozen fertilized eggs for up to ten years. There are times where this 10 year period can be extended. Remember that if you alter your mind about freezing and storing your embryos just let your clinic know. It is also the clinics responsibility to remain in contact with you on a regular basis while your fertilized eggs are being stored away safely with them to ensure you want to continue doing so. Don’t forget to let the clinic know if you change your address or if your situation changes in other ways, for example, if you split up or divorce. In the case of split up for instance, just because this has happened, it does not necessarily mean that either partners consent to use the embryos has been withdrawn.
The medical process used to freeze the embryos is called cryopreservation and uses liquid nitrogen. Embryo storage is subject to the fertilized eggs themselves as only the healthiest specimens will used for freezing. Even when great care is taken however, some embryos do not endure freezing and thawing. One way to ready yourself for this eventuality is to thaw more fertilized eggs than are needed for transfer when the next treatment cycle is due.
