In the first step, an IVF expert deciphers the best time for conducting an IVF cycle.
Once it is done, then in the next step, an egg is separated from the female body.
In the third and final step, this matured egg is stored in a bank. Here, it is kept under the temperature of minus one ninety-six degrees Celsius. Roughly speaking, an egg can be preserved for around nine to ten years. This entire process is also known as the egg freezing process.
When we talk about egg freezing, we are only dealing with the female factor of any pregnancy. Embryo freezing is a different thing. Here you need the participation of both male and female factors simultaneously. During the process of embryo freezing, the support of IVF techniques is required. It means, first a healthy ovum is removed from a female body, then sperm is separated from the semen, and finally, it is fertilized. After the formation of an embryo, it is finally stored. These embryos are also known as frozen embryos. When we compare a frozen embryo with a frozen egg then, in general, we can say that frozen embryos have a better chance of survival against the crystal formation that takes place during the course of freezing. Frozen embryo transfer success rates are very high; according to estimation, on ninety percent of the occasions, it serves the purpose well.
Ideally, most of the experts prefer to store at least ten eggs or six to seven embryos for the purpose of a single pregnancy attempt. Here, we would also like to tell you that, during a single IVF cycle, a woman can produce 20 eggs.
By freezing an egg or an embryo, a female or a couple is actually freezing their fertile age. A woman freezing her eggs at the age of 27, will have significantly higher chances of pregnancy than a woman freezing her eggs at the age of 40.
