What is Egg Freezing and Why Consider It?
Egg freezing, medically called oocyte cryopreservation, lets a woman preserve her eggs at their current quality for use later in life. The eggs are retrieved, rapidly frozen using a technique called vitrification, and stored safely until she is ready to try for pregnancy — whether that is in a few years or later.
At Diwya Vatsalya Mamta Fertility Centre in Patna, we see women considering egg freezing for very different reasons — not being ready for children yet, a medical diagnosis that could affect future fertility, or simply wanting the option kept open. Whatever the reason, the decision deserves an honest conversation about age, ovarian reserve and realistic expectations, not just the procedure itself.
- Delaying parenthood by choice — for career, education or personal readiness.
- Before cancer treatment — chemotherapy or radiation can affect egg quality.
- Low ovarian reserve or family history of early menopause — preserving eggs while quality is better.
- Before surgery for endometriosis or ovarian cysts — some procedures can reduce ovarian reserve.
Egg Freezing Process in Patna
The process is similar to the first half of an IVF cycle — it stops once the eggs are frozen, rather than continuing to fertilisation and transfer.
1. Consultation & Testing
AMH blood test and a pelvic ultrasound to assess ovarian reserve, along with routine health screening, before planning the cycle.
2. Ovarian Stimulation
About 10–12 days of hormone injections to encourage several eggs to mature, with regular ultrasound monitoring.
3. Egg Retrieval
A short procedure under mild sedation, taking 15–20 minutes, to collect the mature eggs.
4. Vitrification & Storage
Mature eggs are flash-frozen the same day and stored securely until needed for future use.
When you are ready to use the eggs, they are thawed and fertilised, and treatment continues as a standard IVF or ICSI cycle at our IVF Center in Patna.
Who Should Consider Egg Freezing?
Egg freezing is a form of fertility preservation. It is not for everyone, but for the women it does suit, it changes what is possible later.
⏳ Delaying Pregnancy for Personal Reasons
Career, further study, waiting for the right partner, or personal readiness — freezing eggs in your late twenties or early thirties preserves better egg quality for use later.
🩺 Medical Conditions Affecting Ovarian Reserve
A diagnosis of low AMH, endometriosis (that may need repeated surgery), or a family history of premature ovarian insufficiency are all reasons to consider preservation early.
🎗️ Before Cancer Treatment (Oncofertility)
Oncofertility is the branch of fertility preservation before chemotherapy or radiotherapy. Egg freezing before treatment can protect the option of a future biological pregnancy where the disease and treatment plan permit.
👥 Before Ovarian Surgery
If surgery for endometriosis, cysts or fibroids may reduce ovarian reserve, freezing eggs beforehand is worth an open conversation.
Egg Freezing Success Rates & Storage
Modern vitrification has largely replaced the older slow-freeze method. Outcomes depend more on the age at freezing than on any other single factor.
❄️ Vitrification vs Slow Freeze
Vitrification — ultra-rapid freezing — achieves egg survival rates of 85–95% on thaw. The older slow-freeze method survived only 60–70% and is no longer standard practice.
🎂 Age at Freezing Matters Most
Eggs frozen under age 35 have the best chance of leading to a live birth. Every additional year of egg age at freezing lowers the eventual outcome, which is why age-appropriate counselling is essential.
🥚 Number of Eggs Frozen
A single cycle typically produces 10–15 mature eggs. For a reasonable chance of one live birth per stored batch, 15–20 mature eggs are generally recommended — sometimes needing two stimulation cycles.
🕐 How Long Can Eggs Be Stored?
Vitrified eggs can be stored for many years without a demonstrated decline in quality. Storage decisions are reviewed each year with clear consent, and continued cryopreservation is confirmed formally.
🧬 Egg Freezing vs Embryo Freezing
Embryo freezing (fertilising eggs first with a partner or donor sperm) gives slightly higher live-birth rates per stored unit, but it is not the right choice for every woman — egg freezing preserves autonomy over future decisions.
💡 An Egg Bank Is Not a Guarantee
Preserved eggs improve options but never guarantee a future baby. The eventual outcome still depends on uterine health, sperm quality, embryo development and the treatment cycle at the time of use.
Egg Freezing Cost in Patna
Egg freezing has two separate cost components — the retrieval and freezing cycle itself, and ongoing storage. Both are explained upfront, with a written estimate before you begin.
| Component | What it covers |
|---|---|
| Consultation & Testing | AMH test, ultrasound, health screening |
| Stimulation & Retrieval Cycle | Hormone injections, monitoring, egg retrieval and vitrification |
| Annual Storage | Ongoing secure storage of frozen eggs, billed yearly |
| Future Thaw & IVF/ICSI Cycle | When you are ready to conceive — billed separately at that time, in the same ₹85,000–₹1,20,000 range as a standard IVF cycle |
Exact pricing depends on your test results and the number of stimulation cycles needed, and is confirmed in writing before treatment starts.
Egg Freezing FAQs
Egg freezing (oocyte cryopreservation) is a procedure where a woman's eggs are retrieved, frozen using a fast-freezing method called vitrification, and stored for future use. When she is ready to conceive, the eggs are thawed, fertilised with sperm, and the resulting embryo is transferred to the uterus.
Egg freezing is commonly considered by women who want to delay childbearing for personal or career reasons, women about to undergo cancer treatment that could affect fertility, women with a family history of early menopause, and women recently diagnosed with conditions such as endometriosis or low ovarian reserve who wish to preserve options.
Egg quality and quantity decline with age, so most specialists recommend freezing eggs before the mid-30s where possible. That said, women in their late 30s can still freeze eggs; the number of eggs needed for a good chance of pregnancy later is simply higher.
The number varies by age and ovarian reserve. A younger woman may retrieve 10 to 15 eggs in a single stimulation cycle, while some women choose to do more than one cycle to bank a higher number of eggs for better future odds.
Frozen eggs can be stored for several years with proper vitrification and monitoring. Storage duration and renewal is discussed and agreed with the patient at Diwya Vatsalya Mamta Fertility Centre, Patna.
The egg retrieval procedure is done under mild sedation and takes about 15 to 20 minutes, so discomfort during the procedure is minimal. Mild bloating or cramping for a day or two afterward is normal.
