Increased fertility problems and the requirement of fertility preservation for later age pregnancy have made egg freezing and embryo freezing procedures common among people. Both these procedures have increased flexibility for a successful pregnancy. However, egg freezing and embryo freezing are completely two different things. These are two ways of fertility beneficial for successful conception. With these methods women can now delay their pregnancy or also conceive even with fertility issues. These methods have their own share of benefits, but the most appropriate for you depends on your medical condition and life goals. If you are confused between these two procedures and wondering which works best for you, visit Nayra IVF, where we have not only excelled in egg freezing but also deliver the best embryo freezing in Noida. We will diagnose your condition, explain to you the suitable procedure, and then continue with the treatment.
What is Egg Freezing?
Oocyte cryopreservation (egg freezing) is the process of egg retrieval, freezing, and storage for later use. Afterward, the eggs are thawed and fertilized by IVF for a successful pregnancy. However, egg freezing is not directly connected to successful live births, but effective egg freezing definitely increases the success rate.
What is Embryo Freezing?
Embryo freezing is a process whereby fertilized eggs and sperm are frozen together in the lab. Like egg freezing, this procedure increases the probability of pregnancy and helps women conceive in the present and future, too. Nayra IVF’s embryologists and fertility specialists use both egg and embryo freezing to help achieve pregnancy.
Key Differences Between Egg Freezing and Embryo Freezing
It is best to fully comprehend the differences between egg freezing and embryo freezing before deciding which is applicable for you. The application of these methods of fertilization differs, although both use cryopreservation and address the problems of the biological clock.
Biological Stage
Egg freezing includes the preservation of fertilized eggs. Mature eggs are extracted and prepared for instant fertilization. Surplus eggs are frozen for future use. One thing that should be duly noted is that only healthy eggs are extracted from the ovaries for IVF stimulation. On the contrary, embryo freezing preserves already fertilized eggs and sperm. These fertilized embryos have already grown into multicelled structures before being frozen.
Procedure
Both these methods have a similar process of IVF stimulation. Hormonal medications are injected into the patients to improve multiple follicles, and after that, eggs are immediately vitrified and stored. However, in the case of embryo freezing, these embryos should undergo proper fertilization in the laboratory. This additional step requires either the male partner’s sperm or donor sperm.
Success Predictability
There are a number of factors that influence the success rate of egg and embryo freezing, particularly the patient’s age, the number of samples stored, and the modern vitrification techniques employed. The clinically proven embryo freezing has a slightly higher and much more predictable success rate (around 40 to 60%) in every transfer compared to egg freezing. This is because embryos are much more robust, and their potential for success is confirmed even before freezing.
Future Flexibility
Egg freezing is more flexible compared to embryo freezing if planned for future use. In egg freezing, individuals are able to preserve fertilized eggs without deciding on a sperm source, either from a future partner or donor sperm. It gives women full control over planning their pregnancy in the future. This can be due to career or clinical reasons, such as genetic conditions, a higher risk of cancer, or other personal reasons. When sperm is used to fertilize the egg (embryo freezing), it limits future options regarding the source of the sperm. But embryo freezing may allow you to have a higher rate of pregnancy success, which is important when considering fertilization.
Financial differences
The expenses for embryo freezing are slightly higher than egg freezing. The average cost of egg freezing ranges from INR 1 lakh to 2 lakh. whereas embryo freezing varies from INR 1.2 lakhs to INR 2.5 lakhs along with additional medication expenses. Because embryo freezing requires fertilization, such as ICSI or traditional insemination, to create embryos, the additional significant laboratory expenses do not increase the cost of egg freezing. However, both of these methods required annual storage expenses ranging from INR 10,000 to INR 30,000.
Storage Process
Egg freezing is a 2 to 3-week process involving the stimulation of hormones for producing multiple eggs. After extraction, these matured eggs are stored in a safe liquid nitrogen tank at minus 196 degrees centigrade for preserving egg fertility for future use. After successful selection of the best quality embryos, they are also frozen for future use.
Ethical and Legal Considerations
In embryo freezing, legal and ethical considerations are common, as both genetic contributors are involved. In the future, if either partner does not continue with the pregnancy, then significant issues arise regarding the future of the frozen embryos. However, in egg freezing, there is no scope for legal disputes or ethical dilemmas because there is only one genetic contributor. For expert assistance in navigating these fertilization choices, Nayra IVF offers advanced legal and medical counseling.
Which one works better: Embryo Freezing or Egg Freezing
In short, as both embryo and egg freezing are significant for successful IVF, what works for you depends on the following factors discussed.
You will choose egg freezing
- If you wish to delay your pregnancy for either professional, personal, or educational reasons.
- There is no partner or donor at this time.
- When you are about to receive long-term medical therapy, such as chemotherapy, affecting your fertility rate, you will want to have eggs saved for future pregnancies.
You will choose embryo freezing
- You have either a partner or a sperm donor now.
- Compared to egg freezing, this procedure has a better fertilization success rate.
- You are currently undergoing IVF and are ready to store additional embryos for future use.
Conclusion
The cryopreservation of eggs or embryos has opened a promising path to the future of reproduction. Embryo freezing and egg freezing both help with the success of IVF, but with egg freezing, you have the freedom to select a partner or donor sperm in the future. So, consult a fertility specialist regarding your suitability for these two methods. If you decide to make an informed decision now, you and your family will be at ease on your pregnancy journey in the future. Our embryologists and fertility specialists provide you with expert guidance and cutting-edge technology at Nayra IVF to help you get advanced egg freezing and the best embryo freezing services.
