What is Egg Freezing?
Egg freezing, also known as oocyte cryopreservation, is a revolutionary fertility preservation technique that allows women to freeze and store their eggs for future use. This procedure offers women the opportunity to extend their fertility timeline, preserve their reproductive potential, and make informed choices about family planning.
Here's what you need to know about egg freezing:
1️⃣ Why Consider Egg Freezing: Many women choose to freeze their eggs for various reasons. These may include career pursuits, educational goals, medical reasons, or simply wanting to ensure the option of having biological children remains available in the future. Egg freezing provides a sense of control and empowerment, allowing women to take charge of their reproductive choices.
2️⃣ The Egg Freezing Process: Egg freezing typically involves several steps, starting with ovarian stimulation. Hormonal medications are administered to stimulate the ovaries to produce multiple mature eggs. During this time, regular monitoring and ultrasound scans are conducted to assess follicle growth. When the eggs have reached optimal maturity, a minor surgical procedure called egg retrieval is performed under sedation. The mature eggs are then frozen using vitrification process and stored in cryostorage tank at -196-degree Celsius which preserves the eggs' viability for an extended period.
3️⃣ Future Use of Frozen Eggs: When a woman decides to use her frozen eggs, they are thawed, and used for fertilization by intracytoplasmic sperm injection (ICSI). The resulting embryos are then transferred into the woman's uterus, with the goal of achieving a successful pregnancy. It is important to note that not all eggs will survive the thawing process, and not all embryos will lead to a pregnancy.
4️⃣ Success Rates: Egg freezing success rates depend on various factors, including the women's age at the time of egg freezing, the number and quality of eggs frozen, and the expertise of the fertility clinic. Generally, when younger women freeze her eggs, she has higher the chances of success in the future in compared with older women.
5️⃣ Emotional Considerations: Egg freezing can be an emotionally significant decision. It provides a sense of security and peace of mind, but it is important to manage expectations and understand that it does not guarantee future pregnancy or the birth of a healthy baby. It is recommended to seek emotional support, counselling, or join support groups to navigate the emotional aspects of the process.
6️⃣ Flexibility and Choice: Egg freezing gives women the flexibility to pursue their personal and professional aspirations without compromising their fertility options. It allows for greater control over family planning and provides the opportunity to build a family when the time is right.
Egg freezing is a proactive step that offers women the ability to preserve their fertility potential, providing a sense of empowerment and peace of mind. If you are considering egg freezing, it's important to consult with a fertility specialist who can assess your individual circumstances, explain the process in detail, and help you make informed decisions aligned with your goals.
The process of egg freezing
Egg freezing, also known as oocyte cryopreservation, is a revolutionary fertility preservation technique that allows individuals to freeze and store their eggs for future use. It provides an opportunity to preserve fertility when circumstances, such as medical treatments, age, or personal choice, may pose a risk to reproductive health. Here is an overview of the process of egg freezing:
1️⃣ Initial Consultation: The journey begins with an initial consultation with a fertility specialist. They will review your medical history, assess your ovarian reserve, and discuss the reasons for considering egg freezing. This consultation provides an opportunity to ask questions, understand the process, and address any concerns.
2️⃣ Ovarian Stimulation: To maximize the number of mature eggs for retrieval, you will undergo ovarian stimulation. This involves the administration of hormonal medications, typically through self-injections, over a period of about 8-12 days. These medications help stimulate the ovaries to produce multiple eggs, rather than the usual single egg that is released during a natural menstrual cycle.
3️⃣ Monitoring: Throughout the ovarian stimulation phase, you will undergo regular monitoring through blood tests and ultrasound scans. These assessments help the fertility team monitor the growth and development of follicles (fluid-filled sacs that contain eggs) within the ovaries. Adjustments to medication dosages may be made based on these monitoring results.
4️⃣ Egg Retrieval: Once the follicles have reached an optimal size and maturity, a minor surgical procedure called egg retrieval is performed. This procedure is typically conducted under sedation or anaesthesia to ensure your comfort. Using ultrasound guidance, a thin needle is inserted into each follicle, and the fluid is aspirated to collect the eggs. The number of eggs retrieved can vary but is usually around 10-15, although it can be more or fewer in individual cases.
5️⃣ Cryopreservation: Following the retrieval, the collected eggs are immediately taken to the laboratory. There, they undergo a process called vitrification, which involves rapidly freezing the eggs to prevent the formation of ice crystals, ensuring the preservation of their cellular structure. The eggs are then carefully stored in specialized cryopreservation tanks, where they can be maintained for an extended period, even several years.
6️⃣ Future Use: When you decide to use your frozen eggs, the thawing process takes place and their viability will be assessed. The eggs will be cultured for couple of hours, and the surviving and healthy eggs are then fertilized through intracytoplasmic sperm injection (ICSI) technique and fertilization checks will be performed the day after. Embryologists will monitor embryos development, and one or more may be transferred into the uterus during a subsequent IVF cycle to achieve a pregnancy. The remaining embryo(s), if any will be frozen for future use.
