Freezing embryos involves performing in vitro fertilization (IVF) in the laboratory by combining the retrieved eggs with a semen sample. This technique allows for the preservation of embryos until desired and provides the opportunity to assess their genetic viability before freezing.
Similar to egg freezing, embryo freezing offers the opportunity to preserve the quality of your eggs and fertility. The key distinction is that in embryo freezing, the eggs have already been fertilized, and the resulting embryos are frozen for future use.
With embryo freezing, the embryos have already passed through crucial stages, including fertilization, which serve as indicators of their quality. Compared to freezing eggs, this process offers greater transparency into the likelihood of successful conception when the time is right.
Embryo freezing offers the advantage of performing genetic compatibility testing, which helps reduce the likelihood of high-risk pregnancies and congenital diseases. We can select embryos with a lower risk of genetic disorders, providing the opportunity for a healthier pregnancy.
Here is a start-to-finish guide for your embryo freezing journey. This is a general roadmap, and our experts will analyze your case and draw up a customized plan of action with you.
Start your egg freezing journey with a consultation where your physician will conduct blood tests, sperm studies, and physical exams. Over the following month, a customized treatment plan will be designed based on the results.
The next step is to stimulate your ovaries to produce a greater number of eggs by self-administering hormone injections. Regular monitoring through blood tests and ultrasounds will help adjust the dosage if necessary. Once the eggs reach full maturity, an injection will trigger ovulation or egg release.
Approximately 35 hours after the trigger injection, you will undergo a minor surgical procedure to retrieve the eggs. Using a small needle passed through the vaginal wall into the follicles, the eggs will be collected. With local anesthesia, you can return to your normal activities within 24 to 48 hours. On the day of retrieval, we will also collect a sperm sample from your partner, or alternatively, a sperm donor can be used.
Our skilled embryologists assess the sperm and egg samples for fertilization. In certain cases, Intracytoplasmic Sperm Injection (ICSI) may be employed, where a single healthy sperm is directly injected into the egg. The resulting embryos are then cultured in incubators for 3 to 5 days before being frozen.
Prior to freezing, optional Preimplantation Genetic Testing (PGT) can be conducted on the embryos. This highly recommended test screens the embryos for over 400 genetic abnormalities, particularly useful for individuals with a history of genetic conditions. Healthy embryos that pass the genetic test will be selected for freezing.
Following their growth in incubators, the embryos undergo rapid freezing through vitrification. To ensure optimal preservation, they are stored in liquid nitrogen tanks at our clinic until you are ready to conceive. You will be provided with precise information regarding the number of healthy embryos successfully frozen during the process.
The first step in freezing your eggs is a consultation with your physician. We will do blood, sperm studies and physical exams during the following month to design your customized treatment plan with you
The next step is to stimulate your ovaries to produce as many eggs as possible. You will give yourself hormone injections to stimulate egg production. You will have to be constantly monitored with regular blood tests and ultrasounds during this process. This way, we can see if your dose needs to be adjusted. Once your eggs have fully matured, an injection will be given that will trigger ovulation or egg release.
Approximately 35 hours after the shot, you will have minor surgery to retrieve your eggs. Your doctor will pass a small needle through your vaginal wall into the follicles. You will receive local anesthesia, and you will be able to return to your normal activities 24 to 48 hours after the egg retrieval. On the day of the retrieval, the couple leaves a sperm sample.
Our embryologists evaluate the sperm and egg sample for fertilization. In some cases, a process called ICSI will be used in which the embryologist will inject a single healthy sperm into the egg. The embryos grow inside an incubator for 3 to 5 days before being frozen.
Before freezing, a PGT genetic test can be performed on the embryos. We strongly recommend that individuals with a history of genetic conditions request these tests, in which embryos will be scanned for over 400 genetic abnormalities. Healthy embryos that successfully pass the genetic test will be frozen.
After their growth in the incubators, the embryos will be quickly frozen through vitrification. To preserve them in the best conditions, we will keep them at the clinic in liquid nitrogen tanks until you want to conceive. We will tell you exactly how many healthy embryos were frozen.
Begin your journey by scheduling a consultation with one of our fertility doctors where we will determine the best course of action for your fertility treatment.
The ovaries undergo stimulation to promote the development of mature eggs, which are then collected through a simple procedure. Next, the eggs are fertilized with a semen sample in the laboratory. Following evaluation for health and genetic viability, the resulting embryos are frozen, preserving them for future use.
