Egg Freezing:
Preserving Fertility for the Future

Egg freezing, also known as oocyte cryopreservation, has emerged as a groundbreaking fertility preservation technique. This procedure involves the extraction, freezing, and storage of a woman’s eggs (oocytes) for potential future use in conception. Primarily chosen by individuals seeking to preserve their fertility due to various reasons, including medical treatments, career pursuits, or personal choices, egg freezing offers a proactive approach to family planning.

The full egg freezing journey

Stimulation and Egg Retrieval

The process of egg freezing begins similarly to IVF, with the individual undergoing ovarian stimulation using hormone medications to prompt the ovaries to produce multiple eggs. Regular monitoring through ultrasounds and blood tests helps determine the optimal time for egg retrieval. Once the eggs reach maturity, a minor surgical procedure, akin to the egg retrieval in IVF, is performed to collect the eggs.


Freezing and Storage

Post-retrieval, the eggs are immediately frozen using a flash-freezing technique called vitrification. This rapid freezing process prevents the formation of ice crystals within the eggs, safeguarding their viability. The frozen eggs are stored in specialized cryogenic tanks, preserving them at extremely low temperatures until the individual decides to use them.


Thawing and Fertilization

When the individual decides to pursue conception, the frozen eggs are thawed in a controlled environment. After thawing, the eggs are fertilized using either conventional IVF or Intracytoplasmic Sperm Injection (ICSI). This process involves injecting a sperm cell directly into the egg to facilitate fertilization.


Embryo Transfer or Egg Thawing

Upon successful fertilization, the resulting embryos are cultured and monitored for viability. Subsequently, the viable embryos can either be transferred into the uterus for implantation (similar to IVF) or, alternatively, the thawed eggs can be used in Intrauterine Insemination (IUI), where sperm is directly placed into the uterus.


Considerations and Success Rates

Egg freezing success rates may vary based on several factors, including the age at which the eggs were frozen and the quality of the eggs. Understanding these considerations, along with the potential risks and limitations, empowers individuals in making informed decisions regarding egg freezing as part of their fertility journey.



Egg freezing has revolutionized fertility options, providing individuals with the opportunity to preserve their reproductive potential. By comprehending the process and its implications, individuals can take proactive steps in family planning, ensuring greater control over their future fertility choices.
