More women in Delhi are asking about freezing their eggs, whether because of career plans, not yet having found the right partner, or simply wanting to keep options open. Oocyte freezing (egg freezing) can genuinely extend a woman’s reproductive choices, but only when it is done with clear information about age, egg numbers and realistic chances. This guide explains elective or “social” egg freezing in practical terms. For an overview of all the options we offer, see our page on oocyte freezing and fertility preservation.
Why women consider oocyte freezing
A woman is born with all the eggs she will ever have. Both their number and their quality decline with age, and the decline becomes steeper from the mid-30s. The chief reason for this is that older eggs are more likely to have chromosomal errors, which lead to failed implantation or miscarriage. Freezing eggs pauses the clock for those particular eggs: an egg frozen at 32 behaves, when thawed years later, broadly like a 32-year-old egg, even if the woman using it is 40.
Common reasons for elective freezing include:
- Delaying pregnancy for education, career or personal reasons.
- Not having a partner yet, while wishing to have a genetically related child later.
- A low AMH or a family history of early menopause, discovered during a routine check.
- Conditions such as endometriosis, or planned ovarian surgery, that may affect ovarian reserve.
Freezing before cancer treatment is a different, time-critical situation, covered in our article on oncofertility preservation before cancer treatment.
Egg freezing best age: why timing matters most
The single most important factor in the success of oocyte freezing is the woman’s age when her eggs are frozen, not her age when she uses them. In general:
- Under 35 is the ideal window. Each egg has a higher chance of being chromosomally normal, and most women respond well to stimulation.
- 35 to 37 still gives reasonable results, though more eggs are usually needed for the same chance of success.
- 38 and above, freezing is still possible, but the chance per egg falls noticeably, and two or more cycles may be needed to bank a meaningful number.
- After about 40, results from a woman’s own frozen eggs are modest, and an honest conversation about alternatives, including embryo freezing or donor eggs, is part of good counselling.
None of this means that freezing at 38 is pointless, only that expectations should match the biology.
How many eggs to freeze
Not every frozen egg becomes a baby. Some will not survive thawing, some will not fertilise, some embryos will stop developing, and some that are transferred will not implant. That is why specialists talk about building a “bank” of eggs rather than freezing a few.
| Age at freezing | General guidance | Points to discuss |
|---|---|---|
| Under 35 | Around 10–15 mature eggs is often suggested | One cycle is frequently enough |
| 35–37 | Around 15–20 mature eggs | A second cycle may be advised |
| 38–40 | 20 or more mature eggs may be needed | Multiple cycles; consider embryo freezing if you have a partner |
| Over 40 | Large numbers are needed for a modest chance | Detailed counselling on alternatives |
These are broad figures from published experience, not guarantees, and the number of eggs one cycle yields depends heavily on your AMH, antral follicle count and response to medication. Your doctor will estimate this from your tests before you start.
Vitrification: how eggs are frozen today
Eggs contain a lot of water, and older slow-freezing methods allowed ice crystals to damage them. Modern clinics use vitrification, an ultra-rapid freezing technique. The egg is briefly placed in protective solutions (cryoprotectants) and then plunged into liquid nitrogen at around minus 196°C, so fast that the contents turn into a glass-like solid without forming ice.
Vitrification has transformed egg freezing. Survival after thawing is now high in experienced laboratories, and fertilisation and pregnancy rates with vitrified eggs approach those of fresh eggs from women of the same age. When the eggs are eventually used, they are thawed and fertilised by ICSI, because freezing hardens the outer shell of the egg. Embryos are then cultured and transferred as in standard IVF treatment.
The oocyte freezing process, step by step
- Consultation and tests. A pelvic ultrasound with antral follicle count, AMH and other blood tests, plus a discussion of your medical history and goals.
- Ovarian stimulation (about 9–12 days). Daily hormone injections, which most women learn to give themselves at home, encourage several follicles to grow at once.
- Monitoring. Four or five ultrasound scans and some blood tests to track follicle growth and adjust medication.
- Trigger injection. When the follicles are ready, a final injection matures the eggs. Egg collection is timed about 34–36 hours later.
- Egg collection. A short procedure under light anaesthesia, using a fine needle guided by vaginal ultrasound. There are no cuts or stitches, and most women go home the same day.
- Vitrification. The embryologist assesses each egg and freezes the mature ones. You are told how many were frozen.
- Recovery. Mild bloating or cramping for a few days is common. Your next period usually arrives within about two weeks.
From the first injection to collection the process takes roughly two weeks, and most women need only a day or two off work.
Realistic chances when you return to use your eggs
It is important to see egg freezing as improving your odds rather than as an insurance policy. Your eventual chance of a baby depends on your age at freezing, the number of mature eggs stored, the quality of the laboratory, and on factors at the time of use, such as your partner’s sperm and the health of your uterus. Many women who freeze eggs go on to conceive naturally and never use them, which is a good outcome too.
Before you start, ask your doctor to estimate how many eggs you are likely to collect in one cycle and what that number might mean for your future chances. Some women choose to do a second cycle straight away to build a larger bank; others decide one cycle is enough for peace of mind. There is no single right answer. It is also wise to keep track of your general health, because conditions such as fibroids or endometriosis, which can develop over the years, may affect the uterus when you eventually come to use your eggs.
Pregnancy at an older age also carries higher risks of blood pressure problems and diabetes in pregnancy, even with younger eggs, so your health at the time of use matters.
Storage, consent and the law in India
Under the Assisted Reproductive Technology (Regulation) Act, 2021, gametes such as eggs may be stored for up to 10 years, and clinics and banks providing storage must be registered under the Act. When you freeze your eggs, you sign written consent setting out how long they will be stored and what should happen to them if you no longer need them, or in unforeseen circumstances. Discuss renewal and the options at the end of the storage period before you begin.
The Act permits ART services for women aged 21 to 50, which is worth keeping in mind when planning how long you might wait before using your eggs. Eggs you freeze for yourself remain yours; the Act does not permit the commercial sale of gametes.
Egg freezing or embryo freezing?
If you have a partner, freezing embryos rather than eggs is another option. Embryos survive thawing well and give information about fertilisation and development at the time of freezing. However, embryos belong jointly to both partners, so their future use requires both partners’ consent. Egg freezing keeps the decision entirely with the woman, which is why it is the usual choice for women who are single or uncertain about the future. Some couples split their eggs, freezing some as eggs and fertilising others.
A consultation with one of our specialists, such as Dr. Ruchi Hooda, can help you weigh these options against your age and test results. You can read more about how we approach egg freezing and fertility preservation at Ridge IVF.

Frequently asked questions
Is egg freezing painful?
Most women find the daily injections manageable, with mild bloating or tenderness as the ovaries enlarge. The egg collection itself is done under light anaesthesia, so you should not feel pain during it. Afterwards some cramping or spotting for a day or two is common and usually settles with simple pain relief. Your team will explain which symptoms need a call to the clinic.
Does freezing eggs reduce my natural fertility later?
No. Each month your body recruits a group of follicles, and normally only one releases an egg while the rest are lost. Stimulation rescues eggs from that monthly group rather than drawing on future reserves. Egg freezing does not bring menopause forward or reduce your chances of conceiving naturally later, although age itself continues to lower natural fertility.
Can I freeze eggs if my AMH is low?
Often, yes, but expectations need adjusting. A low AMH usually means fewer eggs per cycle, so more than one cycle may be needed to store a meaningful number. Egg quality depends more on age than on AMH, so a younger woman with low AMH may still have good-quality eggs. Your doctor will interpret AMH alongside your scan and age.
What happens to my eggs if I do not use them?
When you freeze eggs you record your wishes in a written consent form. At the end of the permitted storage period, or earlier if you decide you no longer need them, the eggs may be allowed to perish or, where permitted, used for research, according to the options you chose. Commercial sale of eggs is not allowed. You can review and update your consent.
