Assisted reproductive technology (ART) means fertility treatments in which eggs, sperm or embryos are handled outside the body to help a pregnancy happen. The best-known example is IVF, but ART also includes ICSI, frozen embryo transfer, egg and embryo freezing, donor programmes, embryo genetic testing and surrogacy, and in India the law also counts IUI. In India, every ART clinic and bank is governed by the Assisted Reproductive Technology (Regulation) Act, 2021. At Yaal Fertility Centre in Chennai, Dr. Rukkayal Fathima and our team help couples work out which of these options, if any, they actually need.
What Does Assisted Reproductive Technology (ART) Mean?
"ART" is an umbrella term. It does not name one treatment, but a family of treatments that share one idea: the doctor and the embryology lab step in at the point where natural conception is getting stuck.
The Simple Definition
In medical use worldwide, ART usually means any treatment where eggs or embryos are handled in a laboratory. Eggs are collected from the ovaries, fertilised with sperm in the lab, grown for a few days, and then placed in the womb or frozen for later.
So when someone asks "what is ART in pregnancy?", the honest short answer is: it is IVF and the family of techniques built around IVF.
What India's Law Counts as ART
India's ART Act uses a wider definition. It describes ART as techniques that try to achieve pregnancy by handling sperm or eggs outside the body and placing the gametes or embryo into a woman's reproductive system. It specifically includes gamete donation, intrauterine insemination (IUI), IVF and gestational surrogacy.
That is why, in India, a clinic that only does IUI must still be registered as an ART clinic. Internationally, IUI is often called a "basic" or non-ART fertility treatment. Both views are correct in their own setting, so do not be confused if you read different definitions online.
What Is Not ART
- Tablets or injections to help you ovulate, with timed intercourse. This is ovulation induction, a fertility treatment but not ART.
- Fertility surgery, such as removing fibroids, opening tubes or treating endometriosis.
- Treating the cause, such as correcting thyroid problems, PCOS management or improving sperm health.
Many couples conceive with these simpler steps and never need ART at all.
Why Do Couples Need Assisted Reproduction?
ART is used when the usual route to pregnancy is blocked, or when simpler treatment has not worked. The most common reasons are:
Female Factors
- Blocked or damaged fallopian tubes, where egg and sperm cannot meet. See blocked fallopian tubes and IVF.
- Ovulation problems that do not respond to tablets, often linked to PCOS.
- Endometriosis, especially moderate or severe.
- Low ovarian reserve or age-related decline in egg numbers and quality.
- Womb conditions that make carrying a pregnancy unsafe or impossible.
Male Factors
- Low sperm count, poor movement or abnormal shape.
- No sperm in the semen (azoospermia), where sperm may need to be taken surgically from the testis.
- Ejaculation problems that make natural conception difficult.
Other Reasons
- Unexplained infertility after a long time trying.
- A known genetic condition in the family that a couple wants to avoid passing on.
- Fertility preservation before cancer treatment, or for women who want to delay pregnancy.
- Single women who want to become mothers with donor sperm, which the Indian law permits.
Types of Assisted Reproductive Technology Compared
The table below lists the main ART options and related treatments, in rough order from simplest to most involved. Each links to our page with full details.
| Treatment | What happens | Who it usually suits |
|---|---|---|
| Ovulation induction (not ART, but often the first step) | Tablets or injections help the ovary release an egg; scans time intercourse | Women who do not ovulate regularly, often with PCOS; open tubes and normal sperm |
| IUI | Washed sperm is placed directly in the womb around ovulation | Mild male factor, unexplained infertility, ovulation problems, donor sperm; at least one open tube |
| IVF | Eggs are collected, fertilised with sperm in the lab, and an embryo is placed in the womb | Blocked tubes, endometriosis, low ovarian reserve, failed IUI, unexplained infertility |
| ICSI | A single sperm is injected into each egg as part of IVF | Low sperm count or movement, surgically retrieved sperm, previous poor fertilisation |
| Frozen embryo transfer | A frozen embryo is thawed and transferred in a later, separately prepared cycle | Couples with spare embryos, after PGT, or when a fresh transfer is not advised |
| Egg freezing and embryo freezing | Eggs or embryos are frozen by vitrification for future use | Before cancer treatment, women delaying pregnancy, spare embryos after IVF |
| Donor programmes | Eggs, sperm or embryos from a screened, anonymous donor are used | Very low or no egg reserve, early menopause, azoospermia, some genetic conditions |
| PGT (genetic testing) | A few cells from an embryo are tested before transfer | Couples carrying a known genetic disease; selected cases of repeated loss or failure |
| Surrogacy | Another woman carries the couple's embryo to birth | Women without a womb or with a medical reason they cannot safely carry a pregnancy |
Two of these are closely compared in our guides on IVF vs IUI and ICSI vs IVF.
The Main ART Procedures Explained
IUI: The Gentlest Step
IUI is simple and done in a few minutes in the clinic. The male partner's semen (or donor semen) is washed in the lab to concentrate the healthiest moving sperm, and a thin, soft tube places it inside the womb around the time of ovulation. It gives sperm a head start, but fertilisation still happens naturally inside the body.
It needs at least one open tube and reasonable sperm numbers. If several well-timed cycles do not work, doctors usually discuss moving to IVF. See when IUI fails.
IVF: The Core of ART
IVF has four main stages:
- Stimulation: hormone injections help several eggs mature, with regular scans to track them.
- Egg collection: a short procedure under sedation collects the eggs through the vagina with a fine needle guided by ultrasound.
- Fertilisation and culture: eggs meet sperm in the lab, and the embryos grow for three to five days.
- Embryo transfer: one embryo is gently placed in the womb through a thin tube, usually without any anaesthesia.
Our complete guide to IVF and the IVF process timeline walk through each stage in detail.
ICSI: IVF for Sperm Problems
In standard IVF, thousands of sperm are placed near each egg and one gets in on its own. In ICSI, the embryologist picks a single sperm and injects it directly into the egg. It is used when sperm are few, weak or taken surgically, or when eggs failed to fertilise in a previous IVF cycle. The rest of the process is the same as IVF.
Frozen Embryo Transfer
Good embryos that are not transferred fresh can be frozen by vitrification, a fast-freezing method that protects them from ice damage. Later, the womb lining is prepared with medicines or in a natural cycle, and an embryo is thawed and transferred. Frozen transfers avoid repeating egg collection and give the body time to recover after stimulation. Read our frozen embryo transfer guide.
Egg and Embryo Freezing
Egg freezing lets a woman store eggs while they are younger, for use later. It is done before cancer treatment that may damage the ovaries, and increasingly by women who want to delay pregnancy for personal reasons. Age at freezing matters most for later chances. Embryo freezing stores already-fertilised embryos and is usually done by couples after IVF. See embryo freezing vs egg freezing.
Advanced and Third-Party ART Options
Donor Eggs, Sperm and Embryos
When a woman has very few or no usable eggs, or a man has no sperm that can be retrieved, donor gametes can make pregnancy possible. Donors are screened for infections, blood group and genetic conditions, and in India they stay anonymous. The baby is legally the child of the intended parents. Read our detailed guide to the egg donor programme in India.
Preimplantation Genetic Testing (PGT)
PGT tests a few cells taken from an embryo, usually on day five or six, before it is transferred. It is most clearly useful when a couple carries a known genetic disease, such as thalassaemia, so that an unaffected embryo can be chosen. It may also be discussed after repeated miscarriage or failed transfers. It cannot guarantee a healthy baby, and it is never used to choose a baby's sex, which is illegal in India. See our guide to PGT and embryo genetic testing.
Gestational Surrogacy
In gestational surrogacy, an embryo made from the couple's eggs and sperm is carried by another woman. In India, only altruistic surrogacy is allowed, for couples with a medical need, and it is governed by a separate law, the Surrogacy (Regulation) Act, 2021, with its own eligibility rules and approval process. Read surrogacy in India: legal rules and eligibility.
How Do Doctors Choose Between ART Options?
There is no single "best" form of assisted reproduction. The choice comes from tests on both partners.
The Tests That Guide the Choice
- Ovarian reserve: an AMH test and an antral follicle count on scan show roughly how many eggs remain.
- Tubes: an HSG or similar test shows whether the tubes are open.
- The womb: a scan, and sometimes a hysteroscopy, checks for polyps, fibroids or scarring.
- Semen analysis: sperm count, movement and shape decide between IUI, IVF and ICSI.
- Age and time trying: the older the woman, the less time it is wise to spend on simpler treatments.
Step-by-Step Care or Straight to IVF
For many couples, care moves in steps: first find and treat the cause, then ovulation induction, then IUI, and IVF if these do not work. This avoids more intensive treatment than needed.
But going straight to IVF or ICSI is sensible when:
- Both tubes are blocked or have been removed.
- Sperm numbers are very low, or there is no sperm in the semen.
- The woman is in her late 30s or older, or has low ovarian reserve.
- A known genetic condition needs embryo testing.
- Several IUI cycles have already failed.
A Note on Cost
Costs vary a great deal between treatments. IUI costs far less than IVF, and add-ons such as ICSI, freezing and PGT increase the total. For a clear breakdown, see our IVF cost in Chennai guide.
India's ART (Regulation) Act, 2021 in Plain Words
India passed the Assisted Reproductive Technology (Regulation) Act in December 2021, with rules following in 2022. Before this, fertility clinics were guided mainly by voluntary guidelines. The Act now makes clear legal standards for every clinic and bank. Here is what it means for patients, in general terms. For specific legal questions, your clinic's counsellor or a lawyer can advise on the current rules.
Clinics and Banks Must Be Registered
- ART clinics (both those that do IUI and those that do IVF and related procedures) must be registered before they can treat patients.
- ART banks, which collect, screen and store sperm, eggs and embryos, must also be registered.
- Registration is renewed periodically, and clinics must meet set standards for staff, equipment and record keeping.
You are entitled to ask any clinic for its ART registration.
A National Registry and Oversight Boards
The Act sets up a National Registry that holds a central database of ART clinics and banks across India, along with national and state boards that advise on policy and oversee the law. Clinics report details of treatments to the registry, which helps track how ART is used in the country.
Who Can Have ART Treatment
- Married couples with infertility, and single women, can seek ART.
- The Act sets age limits: the woman must be above 21 and below 50 years, and the man above 21 and below 55 years.
These limits apply to ART such as IVF and IUI. Surrogacy has different age rules under the separate Surrogacy Act.
Written Informed Consent
No ART procedure can be done without the written informed consent of the couple or woman, and of any donor. Consent covers what will be done, the risks, and what happens to any spare eggs, sperm or embryos. Clinics must explain the treatment, its chances and its costs so that patients can make an informed choice.
Rules for Donors
- Donors remain anonymous, and their identity is kept confidential.
- The child born from donor eggs or sperm is legally the child of the intended parents; the donor has no parental rights.
- Egg donors must meet set criteria, including age limits, and can donate only once in their lifetime, with a limit on how many eggs are collected. The intended parents must arrange insurance cover for the egg donor.
- Buying or selling eggs, sperm or embryos is illegal; donors are compensated only as the rules allow.
Our egg donor programme guide explains donor eligibility in more detail.
Safeguards Built Into the Law
- No sex selection. Choosing an embryo by sex is banned, and PGT may be used only to screen for genetic disease.
- Limits on embryo transfer. The Act limits how many embryos can be transferred in one cycle, to reduce the risks of multiple pregnancy.
- Storage limits. Eggs, sperm and embryos can be stored only for a maximum period, after which they are used, donated for research with consent, or discarded as the rules set out.
- Penalties. Breaking key rules, such as sex selection or selling gametes, is a punishable offence.
ART Act vs Surrogacy Act
| ART (Regulation) Act, 2021 | Surrogacy (Regulation) Act, 2021 | |
|---|---|---|
| Covers | IUI, IVF, ICSI, freezing, donor gametes, PGT, clinics and banks | Surrogacy arrangements |
| Who can use it | Married couples with infertility and single women | Eligible married couples and certain single women, with a medical need |
| Key approvals | Clinic and bank registration, written consent | Medical indication, eligibility and essentiality certificates, court order on parentage |
| Commercial use | Selling gametes or embryos is banned | Only altruistic surrogacy allowed |
Choosing an ART Clinic
What to Check
- ART registration under the Act, for the clinic and any bank it works with.
- Who leads the care, and whether you will see the same doctor through your treatment.
- Honest information about your own chances, based on your age and tests, rather than headline success figures.
- A clear written cost estimate, including medicines and possible add-ons.
- Counselling and support, since ART can be emotionally demanding for both partners.
Questions to Ask at Your First Visit
- What is the most likely reason we have not conceived?
- Which treatment do you suggest first, and why?
- How many cycles of this treatment would you try before changing the plan?
- What are the risks for us, including multiple pregnancy and ovarian hyperstimulation?
- What will happen to any spare embryos?
- What is the total expected cost?

Common Myths About Assisted Reproduction
| Myth | Fact |
|---|---|
| ART means IVF only | ART is a family of treatments; many couples need only IUI or simpler care |
| IVF babies are not "natural" or are less healthy | Most babies born through ART are healthy; the embryo grows in the womb just like any pregnancy |
| ART always leads to twins | Transferring one embryo at a time keeps the twin risk low, and the law limits how many can be transferred |
| Anyone can choose the baby's sex with ART | Sex selection is illegal in India |
| ART works at any age | Age is the biggest factor in success; chances with a woman's own eggs fall steadily after the mid-30s |
Frequently Asked Questions About Assisted Reproductive Technology
What is assisted reproductive technology in simple words?
It means fertility treatments where eggs, sperm or embryos are handled outside the body to help a pregnancy, such as IVF and ICSI. In India, the law also includes IUI, donor gametes and surrogacy.
What does ART mean in pregnancy?
ART stands for assisted reproductive technology. A pregnancy "through ART" usually means it began with IVF, ICSI, IUI or a frozen embryo transfer rather than natural conception.
Is IUI a type of ART?
Under India's ART Act, yes: IUI is included and IUI clinics must be registered. In many other countries IUI is described as a simpler, non-ART fertility treatment.
What is the age limit for ART in India?
Under the ART (Regulation) Act, 2021, the woman must be above 21 and below 50 years, and the man above 21 and below 55 years. Surrogacy has separate age rules.
Can a single woman have IVF in India?
Yes. The ART Act allows single women to access ART, usually with donor sperm.
Is IVF the same as ART?
IVF is the most common type of ART, but not the only one. ICSI, frozen embryo transfer, egg freezing, donor programmes, PGT and surrogacy all fall under ART.
Which ART treatment is right for me?
That depends on tests on both partners, your age and how long you have been trying. A fertility specialist will usually suggest the simplest treatment that fits your situation.
Are babies born through ART healthy?
The great majority are healthy. Most of the extra risk comes from twin pregnancies, which is why single embryo transfer is preferred.
