Introducing our autologous egg bank program.
Egg banking is a method of retrieving and cryopreserving current eggs
so they can be used when preparing for pregnancy in the future.
Since a woman's fertility and egg characteristics can change with age, it is important to consult considering both current health status and future pregnancy plans.


Pregnancy plans can vary depending on individual health status and life schedule. Egg banking can be one option for the future when planning pregnancy is currently difficult.
The age at which eggs are retrieved and stored can have a more significant impact on outcomes than the age at which they are used.
When facing treatments that may affect ovarian function,
such as chemotherapy or radiation, egg preservation can be discussed before treatment.
When it's difficult to prepare for pregnancy due to studies, career, or personal plans, it can be considered as a method for future pregnancy planning.



To grow multiple eggs in the ovaries (controlled ovarian stimulation), ovulation-inducing medications and injections are prescribed from day 2-3 of menstruation. ※ Egg retrieval following the natural cycle is also possible, and the stimulation method is decided after thorough consultation based on the patient's condition.
While monitoring follicle growth via ultrasound 3-4 times, an ovulation trigger injection is administered on the appropriate date when eggs are judged to be mature, and eggs are retrieved approximately 36 hours later.
Retrieved eggs are identified and classified at state-of-the-art facilities for cryopreservation. The procedure is performed under sedation with minimal pain and takes about 10 minutes.



Egg freezing is one method to preserve future pregnancy potential, but it does not guarantee pregnancy. Future outcomes can be influenced by various factors including the age at which eggs were stored, the number and condition of stored eggs, and the post-thaw process.
If you need to delay pregnancy plans for an extended period or are facing treatment that may affect ovarian function, you can consult to evaluate your current ovarian status and future plans. Since age is an important factor, getting an early assessment can be helpful if you're considering storage timing.
After evaluating individual ovarian function and condition, an ovulation induction method is determined, and egg retrieval is performed at the appropriate time while monitoring follicle growth via ultrasound.
Retrieved eggs are stored after confirming their condition and undergoing the freezing process. Vitrification is currently widely used for egg cryopreservation.
