What happens when you freeze eggs, embryos or sperm


IVF (in vitro fertilization) is a scientific process of collection of sperms and eggs separately from male and female partner respectively and then fertilizing them together to create healthy embryos and then replacing them into the female partner’s uterus. There is a growing tendency to freeze sperm or eggs or even the embryos. If properly done, these can be stored safely for as many as ten years. Let us look at what this means.

Liquid nitrogen is usually used for flash freezing (vitrifying) the eggs, sperm or embryos. There is a distinction between Freezing Egg vs. Embryo Freezing, though. If you are a woman who is older than 30 years old, then you might be worried that your eggs might not be healthy and fertile after another decade. Therefore you might want to Freeze your eggs in their present condition and go in for fertilization when you are ready. The other way is to fertilize the sperm and egg and wait for the healthy fertilized embryo to be formed. Once they are ready, you can employ Embryo Freezing Techniques to preserve the healthy embryos and transfer them to your uterus when you are ready or to the uterus of a surrogate mother.

Is it better to freeze eggs or embryos? This is a question you might be asking yourself now. When you freeze your eggs, you get several options for the subsequent part of your plan to have a baby. But when you freeze your embryos, then you have already decided who the father of your child is going to be. When you are finally ready to have your baby, it might be a problem if you develop differences with your partner. On the other hand, with embryo freezing with healthy embryos, a fresh IVF or ISCI cycle needn’t be started again later, and you can simply use the frozen embryos.
