At IVI we are frequently asked questions about the differences between frozen and \u2018fresh\u2019 embryos <\/strong>as part of the process of in vitro fertilisation (IVF). Patients want to know whether to expect the signs and symptoms of pregnancy following the transfer of a frozen embryo to be any different.<\/p>\n

In this IVI blog article, we take a look at the implications of frozen embryo use. Why are frozen embryos created in the first place? When and why are they likely to be used? Is the resulting pregnancy success rate any different? As for the test, is a pregnancy test after IVF frozen embryo transfer<\/strong> any different from the test following any other IVF procedure? Read on for all you need to know about frozen embryo transfer and the subsequent pregnancy test.<\/p>\n

Why do we need frozen embryos?<\/h2>\n

When a woman who needs fertility treatment goes through a cycle of IVF, it involves a period of hormonal medication that stimulates the ovaries to produce multiple eggs. These are fertilised in the laboratory as part of the normal IVF process. This naturally results in the existence, if there are enough good-quality eggs, of several embryos. Why not just one?<\/p>\n

Egg quality <\/strong><\/h3>\n

It\u2019s well known that the quality of your eggs declines with age, regardless of how fit and healthy you are. It\u2019s also a fact of life that for many women, by the time they have tried to conceive for a while, sometimes for many years, and decide to opt for fertility treatment, they can be approaching the age where egg quality starts to decline. The fact that we obtain several embryos in just one treatment would increase the number of attempts and the probabilities of getting pregnant. The surplus embryos are frozen in order to improve these pregnancy rates<\/p>\n

The time taken by fertility treatment<\/strong><\/h3>\n

The most time-consuming aspect of IVF fertility treatment by far is the ovarian stimulation phase. It can take anything from 10 to 15 days. It\u2019s therefore a bonus if, in the event of a single embryo transfer failing to result in a pregnancy, we have \u2018spare\u2019 frozen embryos in reserve. The patient, when she feels ready, can opt for another attempt. In this case she can use a previously frozen embryo, without needing to go through the stimulation phase a second time.<\/p>\n

When are frozen embryos used?<\/h2>\n

We have seen that one of the major reasons for using a frozen embryo is in the event of an unsuccessful IVF attempt. But there are other advantages too.<\/p>\n

Extending your family<\/strong><\/h3>\n

Maybe you have been doubly fortunate. That is, you got a successful pregnancy after IVF and you also have spare good-quality embryos. These can be used at a later time if and when you wish to extend your family. There are some big advantages here.<\/p>\n
