Embryo freezing is a procedure where fertilized eggs (embryos) are stored at sub-zero temperatures using a process called vitrification. When ready, the embryo is thawed and transferred into the uterus during a future IVF cycle.
Unlike freezing eggs, where unfertilized eggs are preserved, embryo cryopreservation involves storing already-fertilized embryos, making it a more advanced solution for couples or individuals ready to fertilize and preserve the embryo immediately.
Frozen embryo storage may be ideal for:
Additionally, embryo freezing is widely used in elective deferred embryo transfers (FET) to allow for endometrial recovery or scheduling flexibility.
The embryo freezing process at Kanaa is an integral part of our IVF services, performed in a highly advanced lab setting:
Patient is seen on day 1 or 2 of periods.
We do a transvaginal scan to confirm the absence of any cysts.
Medication may be started in case of a hormonal cycle
Ultrasound monitoring of the endometrial lining is done starting about day 10 of cycle
Once the lining reaches a satisfactory thickness, progesterone is started,
Embryo transfer is planned after 3-5 days of progesterone depending on whether day 3 or day 5 embryos need to be replaced.
Embryo transfer is done under ultrasound guidance.
Luteal phase support with injections or medicines is advised for two weeks.
Beta hCG blood test is taken after 12 -14 days of transfer.
Embryo cryopreservation offers a powerful way to preserve future fertility. When you’re ready, the embryos are thawed and transferred to the uterus in a new IVF cycle—eliminating the need for repeated ovarian stimulation or egg retrieval. This streamlines the fertility journey and reduces physical and emotional stress.
