Embryo freezing (cryopreservation) at Kanaa Fertility preserves fertilised embryos — formed during an IVF/ICSI cycle — using a fast-freezing technique called vitrification, for use in a future cycle. Two clinics in KK Nagar & Mylapore, with in-person & online consultations.
Embryo freezing (cryopreservation) is the process of freezing fertilised embryos, created through IVF or ICSI, by a technique called vitrification for long-term storage and future use.
Since typically only 2–3 embryos are transferred in a single cycle, any additional good-quality embryos can be frozen and stored for future attempts, without needing to repeat the full stimulation and retrieval process.
Embryos are created in an IVF/ICSI cycle, then frozen by vitrification within days of fertilisation.
Frozen embryos can be used in a future cycle without another egg retrieval.
Vitrification has been used safely since the 1980s with strong success rates.
Embryo freezing is a routine part of many IVF/ICSI cycles — and is also chosen for specific medical or personal reasons.
To avoid the risk of OHSS, extra good-quality embryos from a stimulation cycle are frozen instead of all being transferred at once.
Couples may freeze embryos ahead of treatment that could affect future fertility.
Married couples may choose to freeze embryos to delay starting a family for personal reasons.
Embryos needing genetic testing prior to use are frozen while results are awaited.
A typical cycle involves a stimulation phase (if applicable), egg retrieval and fertilisation, embryo culture, and vitrification for storage. A future frozen embryo transfer involves lining monitoring, progesterone support, and the transfer itself. Starting price to be confirmed by the clinic.
Success with frozen embryo transfer depends on individual factors, including embryo quality at the time of freezing, the woman's age, and endometrial receptiveness at the time of transfer. Your specialist can discuss what's realistic for your specific situation.
Embryo quality and grading, the age of the woman at the time the eggs were collected, and the condition of the uterine lining at transfer.
Your care team monitors embryo quality and survival closely at every stage, from freezing through to thaw.
Consent from both partners is required for embryo freezing and storage, and specific requirements apply under India's ART (Regulation) Act — including maximum storage duration and consent renewal. This should be discussed directly with your specialist.
Depending on your situation, your specialist may also discuss egg freezing (if you don't yet have a partner or are not ready to fertilise) or sperm freezing for the male partner.

Embryo freezing has been in common use since the 1980s and has been proven safe and effective, especially with vitrification. There is a theoretical risk of embryos being damaged or not surviving when thawed, but since only good-quality embryos are chosen for freezing, this risk is negligible in experienced hands.

Yes, informed consent from both partners is required before embryos can be frozen and stored, in line with ART Act requirements.
Embryo freezing preserves fertilised embryos (formed from an egg and sperm), while egg freezing preserves unfertilised eggs. Embryo freezing requires a partner or donor sperm at the time of freezing; egg freezing does not.
