Egg freezing vs. embryo freezing – which option is right for you?

  • Facebook

If you are considering preserving your fertility, there are several options to choose from. Egg and embryo freezing are common ways of preserving fertility, however, it’s important to understand the differences between these two methods to determine which one is right for you. Here’s a little more information to help you make an informed decision.


Preserving your eggs and sperm for the future

The difference between freezing eggs and embryos

Egg freezing is the most common method of preserving a woman’s fertility. This procedure involves undergoing a partial IVF cycle to retrieve eggs from the ovaries. The eggs are then rapidly frozen and stored safely in liquid nitrogen until you are ready to use them.

In contrast, embryo freezing is a way for co-parents or couples to preserve their fertility together. Similar to egg freezing, this process also requires a partial IVF cycle to retrieve eggs. However, in this case, the eggs are fertilised with sperm in a laboratory, allowing them to develop into embryos over five to six days. The healthy embryos are then frozen and stored for future use.


Once an egg has been successfully fertilised, it becomes an embryo, and embryos can be frozen and stored. So if you’re wondering whether you can freeze fertilised eggs, the answer is yes; this is exactly what embryo freezing involves.

The main difference between the two methods is their fertilisation status; the eggs are unfertilised, while the embryos are fertilised. Additionally, individuals have more control over their fertility options when freezing their eggs, since they can be frozen without being fertilised.

With embryo freezing, both partners will need to decide how they are used in the future. Moreover, embryo freezing is often considered to have a slightly higher survival rate than egg freezing when thawed.

Is it better to freeze eggs or embryos?

When considering whether to freeze your eggs or embryos, the decision largely depends on your circumstances and when you feel ready to start a family.

Factors that influence your decision

Several factors can influence your decision regarding freezing your eggs or embryos. One key consideration is your relationship status. If you are single and unsure whether you are ready for children or would prefer to focus on your career, freezing your eggs may be the best option. On the other hand, if you are in a relationship and plan to have children in the future, freezing embryos could be a viable choice.

Age is another important factor to consider. The quality and quantity of eggs decline with age, so it’s recommended to freeze eggs before the age of 35.

Moreover, if you are undergoing cancer treatment or dealing with a fertility condition, taking steps to preserve your fertility earlier can provide you with a better chance of having children later in life.

However, it is important to talk to your doctor about your options to see what works best for you.

Success rates: egg freezing vs. embryo freezing

Approximately 90% of frozen eggs and embryos successfully survive the thawing process and can be used for fertility treatment. However, it’s important to understand that this doesn’t guarantee a successful pregnancy as the outcome is influenced by several factors, including age and lifestyle choices.

During your consultation, we will discuss these factors and work together to determine the best treatment plan to enhance your chances of conception later on.

Cost of freezing eggs vs freezing embryos

Cost can play an essential role in your decision when it comes to preserving your fertility. Generally, egg freezing is less expensive than embryo freezing.

At TFP Fertility, egg freezing costs around £3,695, while embryo freezing costs £5,195. The price difference is due to the complexity of the procedure, as embryo freezing involves egg retrieval, fertilisation and embryo culture.

To help manage your payments, payment plans are available. Rest assured, we will discuss this with you in detail during your consultation.
