What is the difference between Embryo Freezing and Egg Freezing?

The choice between freezing eggs and storing embryos presents a dilemma for women looking for alternate ways of conception so they can put off getting pregnant until later in life. These two independent procedures each attempt to protect a woman’s capacity to conceive and deliver a child through in vitro fertilization (IVF), but each also has particular benefits and drawbacks.


To enable readers to make more informed choices, we are assisting in the clarification of the distinction between freezing eggs and freezing embryos.


First, let’s get to know about these two conception methods in detail:

What is egg freezing?

A woman’s eggs are removed from her ovaries during the egg-freezing procedure and then frozen for later use.


Many factors can influence a woman’s decision to freeze her eggs. Women frequently wish to maintain their fertility so they can try having a family when they are ready in the future. This practice is called “social” egg freezing. Before receiving medical care, such as chemotherapy, that can affect their fertility, women may choose to freeze their eggs. The frozen eggs are defrosted, fertilised, and then transferred to the womb when a woman is ready to use them.

What is embryo freezing?

Using the method of embryo freezing, women can keep fertilised eggs for future use. These eggs will have undergone laboratory fertilisation using either partner or donor sperm.Good grade embryos are frequently left over following embryo transfer in cases of in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). If the therapy is unsuccessful or if the couple decides to try for another child, these embryos can be saved for use later.


Others might decide to freeze their embryos in order to maintain their fertility and use them later to try to conceive. The “freeze all” or elective frozen embryo transfer (FET) procedure is used in this situation. Patients with particular medical issues might gain from getting a FET in some circumstances. Embryos are occasionally frozen for medical research or for donation to others.


The biggest misconception about this conception method is its success rate. An embryo is thought to be less delicate than an egg since it is more fully developed. In the past, this meant that there was a better chance that it would appropriately thaw from its frozen state. However, since the advent of vitrification, a quick freezing process, eggs now thaw at rates that are almost identical to those of embryos — around 90% for eggs and 95% for embryos.

Difference between the embryo and egg freezing process

Both preservation methods follow a similar procedure. First, a woman’s ovaries are stimulated with medicine so that several eggs can mature at once. To ascertain when the ovaries are prepared for egg harvesting, our fertility specialist keeps track of the woman’s egg growth.


Following a quick surgical procedure, these eggs are removed from the body and brought to our embryology lab for examination. Three-quarters of the recovered eggs are typically deemed mature and healthy enough to produce an embryo when fertilised by IVF after assessment.


The highest-quality, most mature eggs are cryopreserved following retrieval in egg freezing. Later on, they can be defrosted and fertilised using sperm from a partner, a known donor, or an unidentified donor.Remember that not all of the frozen eggs will thaw and try fertilisation to develop into embryos.


The key distinction between freezing embryos and other methods is that an egg is fertilised with sperm in a laboratory following retrieval. Hopefully, fertilised eggs will produce embryos, and those that do are frozen, thereby completing two-thirds of an IVF cycle. These embryos may be frozen and then used at a later time for the IVF embryo implantation process.


Either option is a good one if a person wants to put off getting pregnant until later in life. Storage of frozen eggs or embryos can maintain both safety and security indefinitely. The most crucial decision is making a decision when egg quality is still viable.
