Egg freezing and fertility preservation in India

Freezing eggs, sperm or embryos keeps the option of a biological family open for later. People consider it for very different reasons: before cancer treatment that may damage fertility, before surgery on the ovaries or testes, or simply because they are not ready to have a child yet. The procedures are much the same whichever the reason. The urgency, the questions worth asking and the decisions you will be asked to sign are not.

This guide explains what fertility preservation involves, what the Assisted Reproductive Technology (Regulation) Act, 2021 says about freezing and storage, and what to check before choosing a clinic. It is written for patients and for the doctors, oncologists among them, who refer them. It publishes no success rates and no prices, because this directory holds neither for any clinic, and it is not clinical advice: whether freezing is right for you is a decision to make with a specialist. Everything it refers to can be found from the directory home.

What fertility preservation means

The UK fertility regulator, the HFEA, defines it in one sentence: “Preserving your fertility involves freezing your eggs, sperm, embryos or reproductive tissue so that you can hopefully have a biological family in the future.” The qualifier in that sentence is deliberate. Freezing preserves material, not a result, and nobody can promise what a frozen egg or embryo will lead to years later.

Indian law covers the same ground. The ART Act describes itself as addressing reproductive health where assisted reproduction is needed for becoming a parent or “for freezing gametes, embryos, embryonic tissues for further use due to infertility, disease or social or medical concerns.” Freezing for social reasons, because you are not ready yet, therefore sits inside the Act's own statement of its scope, alongside freezing for medical reasons. The Act also defines what it means by freezing. In section 22, to cryo-preserve means “the freezing and storing of gametes, zygotes, embryos, ovarian and testicular tissues”, so tissue as well as eggs, sperm and embryos falls under the same rules.

The options: eggs, embryos, sperm and tissue

Egg freezing. The HFEA describes the process plainly: “It involves collecting a woman’s eggs, freezing them and then thawing them later on so they can be used in fertility treatment.” The first half is the same as the start of an IVF cycle. Drugs stimulate the ovaries, the eggs are collected under sedation, and instead of being fertilised they are frozen. “The eggs will then be frozen either by cooling them slowly or by vitrification (fast freezing) and stored in tanks of liquid nitrogen.” The egg freezing page sets out the procedure in more detail.

Embryo freezing. Eggs can instead be fertilised first and the resulting embryos frozen, which needs sperm from a partner or a donor at the time. The difference matters later. An embryo created with a partner belongs to a joint decision: section 22(4) of the Act says “Any of the commissioning couple may withdraw his or her consent under sub-section (1), any time before the human embryos or the gametes are transferred to the concerned woman's uterus.” Frozen eggs carry no such second consent. The embryo freezing page explains how embryos are frozen and used.

Sperm freezing. For men, the HFEA says “Sperm freezing is the most effective method of preserving fertility”. A sample is usually produced at the clinic, tested and frozen in several portions, so that not all of it has to be thawed at once. A semen analysis is normally done first.

Tissue freezing. Where eggs or sperm cannot be collected, tissue can sometimes be frozen instead. In the HFEA's words, “Ovarian tissue freezing is a fertility preservation option for patients who are unable to freeze their eggs and for younger people who haven't started ovulating.” Testicular tissue freezing is described as “a specialist technique to preserve the fertility in people who do not produce viable sperm in their ejaculate (azoospermia) as well as younger people who are unable to produce an ejaculate.” Both are specialist work that not every clinic offers, so ask directly rather than assume.

Before cancer treatment

For someone about to start cancer treatment, time is the constraint. The HFEA explains why freezing is raised at all: “This is because some of the drugs used in cancer treatment can cause infertility, especially in high doses.” Egg freezing cannot be done in an afternoon. Of the stimulation that comes before collection, the HFEA says “You'll then start the IVF process, which usually takes around two to three weeks to complete.” Sperm freezing is quicker, but it still has to happen before treatment begins.

That makes the referral the critical step. The oncologist and the fertility specialist need to agree on timing, and the fertility clinic needs to be able to see the patient quickly. If you are referring, ask the clinic how soon it can see an urgent case and whether it can start stimulation at any point in the menstrual cycle. If you are the patient, it is reasonable to raise fertility at your first oncology appointment rather than wait to be asked. The fertility preservation page covers the medical side.

Freezing because you are not ready yet

Elective egg freezing rests on a simple biological fact, which the HFEA states directly: “A woman’s chances of conceiving naturally fall as she gets older because the quality and number of her eggs drops.” The idea, in its words, is that “Egg freezing can be an attempt to preserve fertility by freezing the eggs when the woman is young and the eggs are of the highest quality.”

The same source is careful about what freezing can promise. It calls egg freezing “becoming more successful but by no means a guarantee of having a baby”, and it puts the central risk without softening it: “The major risk is that it won’t work”. A clinic that quotes you results for frozen eggs should be able to say how they were counted, for which age group and over what period. This directory publishes no success rates for any clinic, and the guide to choosing an IVF clinic explains why.

What happens when you use frozen eggs

Frozen eggs are not used on their own. When you decide to use them, they are thawed and fertilised, and the HFEA notes that “Eggs that have been frozen and thawed must be fertilised using a fertility treatment called ICSI”, because freezing toughens the outer layer of the egg. ICSI is laboratory work, so it is done at a clinic registered at Level 2. The guide to clinic levels explains what that registration covers. Any embryos that result are transferred in the same way as in any IVF cycle, and the treatments guide explains the steps.

The risks of the procedure itself

Collecting eggs for freezing involves the same drugs and the same procedure as IVF, so it carries the same risks. The HFEA's summary is that IVF is mostly safe, but it warns about one complication in particular: “These are usually mild, but in extreme cases women can develop ovarian hyperstimulation syndrome (OHSS), which is potentially fatal, so you should familiarise yourself with the symptoms.” Under section 21(c) of the ART Act the clinic must tell you about the side effects and risks of a procedure before you agree to it, so ask what symptoms to watch for and whom to call out of hours.

What the ART Act says about consent and storage

Freezing involves more paperwork than most treatment, because you are deciding now about something that may happen years from now. Three provisions of the Act matter most.

Instructions for death or incapacity. Section 22(2) says “The clinics and banks shall not cryo-preserve any human embryos or gamete, without specific instructions and consent in writing from all the parties seeking assisted reproductive technology, in case of death or incapacity of any of the parties.” Before anything is frozen, you will be asked to state in writing what should happen to it in those circumstances. Take the question seriously and keep a copy of what you sign.

How long storage lasts. Section 28(2) says “The gamete of a donor or embryo shall be stored for a period of not more than ten years”, after which it is to be allowed to perish or donated for research with consent. That wording addresses a donor's gametes and embryos; it does not set out, in that section, a separate period for a person's own frozen eggs or sperm. Ask the clinic, in writing, what storage period it applies to your material, what renewal involves, and what happens at the end of it. Keep your contact details current with the clinic. The HFEA's advice to UK patients applies just as well here: “It is therefore essential that you keep your contact details up to date with your clinic as you will need to be contacted.”

Moving stored material. Section 29 restricts transfers: “The sale, transfer or use of gametes, zygotes and embryos, or any part thereof or information related thereto, directly or indirectly to any party within or outside India shall be prohibited except in the case of transfer of own gametes and embryos for personal use with the permission of the National Board.” If you might later want to move stored eggs or embryos to another clinic, or abroad, ask before freezing how the clinic handles a transfer.

Who may be treated is also set out in the Act. Section 2 defines a woman, for the Act's purposes, as “any woman above the age of twenty-one years who approaches an assisted reproductive technology clinic or assisted reproductive technology bank for obtaining the authorised services of the clinic or bank”, so a single woman is within its scope. Section 21(g) requires clinics to apply assisted reproduction “to a woman above the age of twenty-one years and below the age of fifty years”. How a clinic applies that limit to freezing on its own, as distinct from treatment, is worth asking before stimulation starts. The guide to your rights under the ART Act covers consent and confidentiality in full.

Choosing a clinic for freezing

Egg collection and freezing are laboratory work, so the clinic that does them needs to be registered under the ART Act and should display its certificate with the dates it is valid for. Beyond registration, ask about the storage itself: where the tanks are, how they are monitored, who is alerted if something fails, and what happens to stored material if the clinic closes or changes hands. Ask whether storage is billed separately from collection and freezing, and how it is billed. This directory holds no prices, so it cannot tell you.

Pages such as egg freezing in Mumbai, egg freezing in Bengaluru and fertility preservation in Chennai list the clinics in a city that name the treatment on their own website. That is the clinic's own statement, not a check of its laboratory, so the questions above still apply. To see every registered clinic in a city, start from the clinics index or a city page such as Hyderabad or Delhi, and the fertility doctors index lets you look up a doctor by name.

Questions to ask before you freeze

• Is the clinic registered under the ART Act at the level the work needs, and is the certificate on display with its validity?
• For your situation, is it better to freeze eggs, embryos or both, and why?
• How long will stimulation take, and can it start at once if treatment for another condition is waiting?
• What will you be asked to sign about death or incapacity, and can you take the forms home first?
• What storage period does the clinic apply, how is it renewed, and what happens at the end of it?
• How are the storage tanks monitored, and what happens to stored material if the clinic closes?
• If you later want to move your eggs or embryos, what does the clinic need from you?

For doctors referring a patient

The single most useful thing a referring doctor can do is refer early, before treatment that threatens fertility has begun, and say so in the referral. Name the planned treatment and its start date so the fertility clinic can judge what is possible in the time available. Each clinic page in this directory shows the registration number recorded in the National ART & Surrogacy Registry extract, and the level where the extract records one. Where the level is missing, the clinic's certificate is the authority, and the treatments index describes each procedure a patient may be offered.

Statements about the law are quoted from the Assisted Reproductive Technology (Regulation) Act, 2021. Statements about procedures are quoted from the patient pages of the UK's Human Fertilisation and Embryology Authority (HFEA). UK law on storage differs from Indian law, and where it matters the Indian text is quoted instead. Rules made under the Act can change, so check the current position with the clinic. Facts about clinics come from the National ART & Surrogacy Registry extract this directory holds and from each clinic's own website. Nothing in this guide is clinical advice, and nothing in it is sponsored.
