Imagine you have a friend who wants to have a baby, but nature isn't cooperating. Maybe the fallopian tubes are blocked, or the sperm count is very low, or the woman's age makes it difficult. For decades, that was the end of the story. But today, doctors have a toolkit of medical procedures that can step in and help — that toolkit is called Assisted Reproductive Technology, or ART.
At its simplest, ART is any medical technique that handles a human egg or sperm outside the body to help a person get pregnant. The most famous example is IVF (in vitro fertilisation), where the egg and sperm are combined in a lab dish — "in vitro" means "in glass" — and the resulting embryo is then placed into the woman's uterus. But ART is broader than just IVF. It includes everything from injecting a single sperm directly into an egg (ICSI) to using a donor's egg or sperm, or even having another woman carry the pregnancy (surrogacy).
The NCERT textbook (Class 12 Biology, Chapter 4) defines ART as all techniques that involve the direct handling of gametes (sperm and eggs) or embryos outside the body to achieve pregnancy. This is the key distinction: if the procedure doesn't involve handling eggs, sperm, or embryos in a lab, it's not ART.
Why does this matter for a commerce or humanities student? Because ART is not just a medical story — it's a social, legal, and economic one. It raises questions about who can afford it (it's expensive), who gets to be a parent (single people, same-sex couples), and what happens to unused embryos (legal and ethical debates). In India, the Assisted Reproductive Technology (Regulation) Act, 2021 now governs these procedures, requiring clinics to be registered and banning commercial surrogacy for foreigners. So when you read about "test-tube babies" or "surrogacy laws" in the news, you're looking at ART in action.
Here are the main techniques you should know, as listed in the NCERT:
- IVF (In Vitro Fertilisation): Egg and sperm are mixed in a lab dish. The embryo is then transferred to the uterus.
- ICSI (Intracytoplasmic Sperm Injection): A single sperm is injected directly into an egg. Used when sperm count is very low.
- GIFT (Gamete Intrafallopian Transfer): Eggs and sperm are placed directly into the fallopian tube, so fertilisation happens inside the body.
- ZIFT (Zygote Intrafallopian Transfer): A fertilised egg (zygote) is placed into the fallopian tube. …
Assisted reproductive technologies are special techniques developed to help infertile couples conceive, and several distinct procedures fall under this umbrella depending on exactly where fertilisation happens and where the resulting embryo is placed. …
Assisted Reproductive Technologies (ART) are special techniques used to help infertile couples have children.
Some important Assisted Reproductive Technologies (ART) are:
- In Vitro Fertilisation (IVF) — fertilisation of the ovum with sperm outside the body, in a laboratory, followed by transfer of the resulting embryo (up to the 8-blastomere stage) into the mother's fallopian tube ('test-tube baby' programme).
- Gamete Intra-Fallopian Transfer (GIFT) — transfer of an ovum collected from a donor into the fallopian tube of another female (recipient) who cannot produce her own eggs.
- Zygote Intra-Fallopian Transfer (ZIFT) — transfer of an early embryo (up to 8 blastomeres), formed by IVF, into the fallopian tube. …

An embryo with more than 8 blastomeres is placed in the uterus by Intrauterine Transfer (IUT); an early embryo (up to 8 blastomeres) goes into the fallopian tube (ZIFT).
In assisted reproductive technologies, embryos produced in the laboratory are transferred into the female. If the embryo is at an early stage — up to the 8-blastomere stage — it is transferred into the fallopian tube by Zygote Intra-Fallopian Transfer (ZIFT). If the embryo has more than 8 blastomeres, it is transferr …

GIFT stands for Gamete Intra-Fallopian Transfer - collected sperm and egg are transferred into the fallopian tube.
GIFT is an Assisted Reproductive Technology (ART) used to help couples who cannot conceive naturally, especially those with a healthy uterus but who cannot produce an ovum (e.g., due to ovarian issues). In this technique, an ovum from a donor female is collected and transferred, along with the sperm, into the fallopian tube (oviduct) of the recipi …

Read the passage given below and answer the following questions : In case of an infertile couple male has abnormally low sperm count in ejaculation and female has blocked oviduct & has spermicidal secretions in vagina but can provide suitable environment for development of embryo. What is infertility ?
›Reveal solutionSolution
Infertility is diagnosed when a couple fails to achieve conception/pregnancy despite regular unprotected sex over an extended period, and can arise from a defect/deficiency in either partner.
Infertility is defined as the inability of a couple to produce/conceive a child even after normal, unprotected sexual cohabitation for a reasonable period of time (typically taken as one year or more of regular attempts). Its causes can be physical, congenital, disease-related, drug/immunological or even purely psychological, and may lie with either the male partner (e.g. low sperm count, blocked ducts), the female partner (e.g. blocked oviducts, hormonal issues), or both. In cases such as the one described here — a male with an abnormally low sperm count and a …
- CBSE 2026Set ANNUAL1 markQ.Refer to the Case Study - 1 passage above (infertile couple with low sperm count and blocked oviduct with spermicidal vaginal secretions). Suggest ART used in above case.
›Reveal solutionSolution
Since the female's oviduct is blocked (preventing normal gamete transport and fertilisation in vivo) but her uterus can support an embryo, and the male has a low sperm count, the couple needs fertilisation to happen OUTSIDE the body, followed by placing the resulting embryo directly into the uterus (or an unblocked part of the oviduct).
Given that (i) the female partner has a blocked oviduct — meaning sperm and egg cannot naturally meet or the fertilised egg cannot travel down to the uterus — but her uterus can support embryonic development, and (ii) the male partner has a low sperm count, the appropriate ART is:
- IVF (In Vitro Fertilisation): ova collected from the female and sperm from the male are made to fuse in the laboratory ('test tube baby' technique) — this fertilisation step does not require an unblocked oviduct.
- ICSI (Intracytoplasmic Sperm Injection): used alongside IVF because of the male's low sperm count, a single healthy sperm is directly injected into the ovum to ensure fertilisation. …

Intra-uterine insemination (IUI) is used to overcome infertility due to low sperm count.
In IUI, semen collected either from the husband or a healthy donor is artificially introduced into the uterus of the female. It is the assisted reproductive technology specifically recommended when the male partner is unable to inseminate the female or has a very low sperm count.

- CBSE 2024Set 57/1/11 markMCQQ.For Questions number 13 to 16, two statements are given — one labelled as Assertion (A) and the other labelled as Reason (R). Select the correct answer to these questions from the codes (A), (B), (C) and (D) as given below. (A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A). (B) Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A). (C) Assertion (A) is true, but Reason (R) is false. (D) Assertion (A) is false, but Reason (R) is true. Assertion (A): The laws of our country permit legal adoption and it is as yet, one of the best methods for childless couples looking for parenthood. Reason (R): Emotional, religious and social factors are no deterrents to the legal adoption of orphaned and destitute children in India.
›Reveal solutionSolution
The Assertion is true — legal adoption is a permitted and valued method for childless couples — but the Reason is false, because emotional, religious, and social factors do act as deterrents to adoption in India.
This is an Assertion-Reason question drawn from NCERT Class-12 Biology, Chapter 4 "Reproductive Health," in the section on Infertility. The chapter notes that legal adoption is one option available to infertile couples wishing to have a child, alongside Assisted Reproductive Technology (ART) methods such as IVF, ZIFT, GIFT, and artificial insemination.
Examining the Assertion: India's legal framework — including personal-law adoption statutes and the secular Juvenile Justice (Care and Protection of Children) Act, 2015 — permits legal adoption, and it remains one of the most widely available, legitimate routes to parenthood for couples unable to conceive. The Assertion is therefore true.
Examining the Reason: The Reason claims that emotional, religious, and social factors are no deterrent to adoption. In practice, the opposite is true. Many couples in India still hesitate to adopt because of the emotional preference for a biological child, religious/cultural expectations (such as the wish for a biological heir), and the social stigma attached to a child "not of one's own blood." These are real, well-recognised deterrents — so the Reason, as stated, is false. …
