Egg freezing in Mumbai at Zoi Fertility is a decision about time. It preserves your current egg quality against the biological clock so that if you need IVF in the future, you are working with eggs from the age you are now, not the age you will be then. Dr Yashodhara, with over 27 years of experience in fertility medicine, personally guides every egg freezing cycle at Zoi Fertility.

What is egg freezing?
Egg freezing in Mumbai, also known as oocyte cryopreservation, is a procedure in which mature eggs are retrieved from your ovaries, vitrified (flash frozen), and stored at minus 196 degrees Celsius. The eggs are not fertilised at this stage. They remain your eggs, held in a state of biological suspension, until you are ready to use them.
When you decide to proceed, the eggs are thawed, fertilised with sperm in the laboratory via ICSI, and the resulting embryos are cultured and transferred to your uterus. The process from that point is identical to a standard frozen embryo transfer cycle.
What vitrification changes
Earlier egg freezing methods used slow cooling, which allowed ice crystals to form inside the egg and damage its structure. Vitrification eliminates this by cooling the egg so rapidly that it transitions directly from liquid to a glass like solid state with no crystal formation. At Zoi Fertility, we use the latest vitrification technology to ensure the highest possible survival rates when your eggs are eventually thawed.
Egg freezing in Mumbai is increasingly popular among women who want to preserve their fertility options while focusing on career, education, or personal goals. According to the Indian Council of Medical Research (ICMR), egg freezing is a recognised and safe procedure when performed at accredited clinics. At Zoi Fertility, with over 5,400 IVF cycles performed and a 68% success rate, you can be confident that your eggs are in expert hands.
Yes. Decades of data from thousands of births globally show no increased rate of chromosomal abnormalities, congenital conditions, or developmental issues in children born from vitrified eggs compared to those born from fresh cycles or natural conception.
The egg freezing process does not alter the genetic material inside the egg. The chromosomes that determine your child’s biology are preserved exactly as they are at the time of freezing. Vitrification affects the cell structure, not the DNA.
Egg quality declines with age. This is not a gradual trend — it accelerates after 35. The eggs you have at 32 are biologically different from the eggs you will have at 38. Chromosomal abnormalities become more common; fertilisation rates drop; embryo quality decreases.
When you freeze eggs at 32, you preserve eggs from that biological age. If you use them at 38, the IVF cycle works with the quality profile of your 32-year-old eggs — not your 38-year-old ones. This is the clinical logic behind social egg freezing: you are not buying certainty. You are buying a better starting position if you need fertility treatment later.
This advantage is real but not unlimited. Frozen eggs do not guarantee a pregnancy. Age at freezing, number of eggs frozen, and individual ovarian response all determine the probability of eventual success. Dr. Yashodhara will give you a realistic assessment of what your specific egg count and AMH level mean for your probability profile — before you make a decision.
An egg is the largest cell in the human body. Sperms and embryos are technically easy to freeze. Egg contains a lot of water inside, and when frozen can form crystal ice, which can cause trauma to the cell. The newer techniques now, dehydrate the cell, and then frozen, thereby preventing crystal ice formation. This technique is called Vitrification used for cryopreservation of eggs or oocytes (technical word). Zoi Fertility only uses vitrification for all their egg freezing cycles.
Vitrification for egg freezing is a relatively new procedure and less than 5% of clinics are doing it since 2012. The chance of success is largely determined by the woman’s age at the time of freezing. Currently, we would expect we could retrieve 85% or more eggs which are frozen.
Success rates are lower for women over 35 than for someone who is in their twenties or early thirties.
The process follows the same initial steps as IVF stimulation. You take injectable hormones for 10–12 days to stimulate your ovaries to produce multiple follicles. The growth of those follicles is monitored by ultrasound every 2–3 days. When follicles reach the target size, a trigger injection is administered to mature the eggs.
Egg retrieval is performed 36 hours after the trigger, under conscious sedation, using a transvaginal ultrasound-guided needle. The procedure takes approximately 20 minutes. Most patients go home the same day.
Retrieved eggs are immediately assessed by our embryologist. Mature eggs (those at the MII stage) are vitrified. Immature eggs cannot be frozen and are not stored. The number of mature eggs retrieved varies with age, AMH level, and ovarian response — typically between 8 and 15 in a good responder in her early 30s.
Eggs are stored in our cryopreservation facility at -196°C, in individually labelled straws, with a continuous electronic monitoring and alarm system.
The costs involved are towards the following parameters
Egg freezing in Mumbai at Zoi Fertility usually costs between INR 1,50,000 to 2,00,000 depending on your age, hormonal values, and the number of eggs retrieved. At Zoi, the costs reduce if you do multiple egg pick up attempts to freeze your eggs.
If you are considering egg freezing in Mumbai, book a consultation with our team to discuss your options. We also offer IUI treatment, donor egg IVF, IVF with ICSI freeze all, and surrogacy services. Check our IVF cost page for transparent pricing details.
EGG FREEZING IN MUMBAI
You are not running out of time. You are buying it.
Egg freezing — oocyte vitrification — is the most consequential fertility decision a woman in her 30s can make. Not because something is wrong. Because biology does not negotiate with career timelines, relationship readiness, or personal circumstances. At Zoi Fertility, egg freezing is treated with the same clinical seriousness as an active IVF cycle. The eggs you freeze today may become the embryos that construct your family in five or ten years. They deserve a laboratory environment — and a medical team — that respects that weight.
Dr Yashodhara has guided patients through this decision for over 27 years. She will not sell you urgency. She will give you data.
Every number reflects the laboratory environment and clinical system that protects your frozen eggs.
THE SCIENCE
Zoi uses vitrification — an ultra-rapid freezing technique that prevents ice crystal formation within the egg. This is the global standard for oocyte cryopreservation, delivering 95%+ survival rates upon thawing. Your eggs are flash-frozen at a rate that preserves cellular integrity at the moment of retrieval.
Frozen eggs are stored in Zoi’s continuously monitored cryogenic facility. Temperature stability, liquid nitrogen levels, and storage integrity are tracked digitally around the clock. The laboratory is supervised by an Oxford-trained senior embryologist with experience across thousands of vitrification and thawing cycles.
Not every woman’s ovaries respond identically to stimulation medication. Dr Yashodhara calibrates your protocol to your AMH levels, antral follicle count, and age — drawing on 5,400+ IVF cycles of experience. The goal is maximal egg yield with minimal discomfort. Monitoring is frequent, adjustments are made in real time, and the egg retrieval itself takes 15–20 minutes under sedation.
TIMING YOUR DECISION
The clinical answer: as early as possible after 28, ideally before 35. The candid answer: whenever you have the clarity that your timeline for children is uncertain.
Egg quality declines measurably after 35 and more steeply after 38. Freezing eggs at 30–33 preserves oocytes at their most viable stage. Freezing at 36–38 is still valuable — but typically requires more eggs, and potentially more than one retrieval cycle, to achieve the same probability of a future live birth.
Dr Yashodhara will assess your ovarian reserve through AMH testing and antral follicle count, then give you a realistic expectation of how many eggs can be retrieved and what that means for your future options.
No manufactured urgency. Just the clinical picture, clearly drawn.
Zoi’s egg freezing programme is priced transparently. The consultation, stimulation monitoring, egg retrieval, and vitrification are quoted upfront — before any medication begins. Annual storage fees are communicated in advance. There are no hidden laboratory surcharges or equipment premiums.
For women considering egg freezing as part of a broader fertility preservation plan — whether due to medical treatment such as chemotherapy, endometriosis management, or personal timing — Dr Yashodhara offers a structured evaluation that maps out the options clearly.
Your eggs are an investment in your future. Zoi treats the pricing with the same precision as the science.
A clinical evaluation with Dr Yashodhara will tell you exactly where you stand — AMH, follicle count, and a realistic timeline.
