embryo freezing has quickly become a popular treatment for those looking to buy time to start a family. embryo freezing differs slightly from egg freezing, in that it occurs after the eggs have been fertilized and developed into embryos, but they start the same way. there are pros and cons to both.
the great news is that after the embryos develop in the lab for a few days and are frozen, they too stay that age. this preserves young and healthy embryos indefinitely. the survival rate of freezing and thawing embryos is slightly higher compared to just eggs, because embryos are less delicate than eggs. but with modern technology this difference is miniscule.
no matter when you freeze or how healthy you are – not every egg will fertilize and mature into an embryo. whether you fertilize eggs before or after they are frozen, the number of embryos you get won’t change much. embryo freezing may not be useful for single parents – because it requires sperm before freezing. the sperm that fertilizes your embryo may not be the co-parent you want in the future.
but for many couples, embryo freezing is a great solution if you want to preserve your fertility and have kids at a later time. usually people will come back after a few weeks or a few years for the embryo transfer with the hopes of achieving a pregnancy. finally, you can hit snooze on your biological clock.
