Medical termination of pregnancy (MTP)
NCERT Class 12 Biology Chapter 3 Section 3.3
Quick answer
Medical termination of pregnancy is induced abortion, distinct from spontaneous pregnancy loss. India’s amended MTP Act has 20/24-week provisions with specified grounds, safeguards and exceptions; NCERT’s legal box contains outdated thresholds. Safety depends on gestational duration, method and appropriate care, and is not restricted to the first 12 weeks.

What is medical termination of pregnancy?
Medical termination of pregnancy (MTP)
Intentional or voluntary termination of pregnancy before full term is called medical termination of pregnancy (MTP) or induced abortion.
NCERT Biology (Class 12), Section 3.3, page 46
- Whether to accept or legalise MTP is debated in many countries because of the emotional, ethical, religious and social issues involved (page 46).
- The Government of India legalised MTP in 1971, with strict conditions to avoid its misuse; such restrictions are all the more important to check indiscriminate and illegal female foeticides, which are reported to be high in India (page 46).
In plain words: MTP is an abortion brought about on purpose, as distinct from one that happens on its own. Indian law allows it on stated grounds, within time limits and by registered medical practitioners, under the MTP Act. Safe abortion care and the separate prohibition of sex selection should not be conflated.
How common MTP is
NCERT says that nearly 45 to 50 million MTPs are performed in a year all over the world, about 1/5th of all the pregnancies conceived in a year (page 46).
Beyond the NCERT text: the World Health Organization’s fact sheet on abortion now estimates about 73 million induced abortions worldwide each year, about 3 in 10 (29 per cent) of all pregnancies (WHO, “Abortion”). Learn NCERT’s figures for NCERT-based questions; the WHO estimate is the more recent one.
Why MTP is done
NCERT gives two kinds of reasons (page 46):
- to end unwanted pregnancies, whether due to unprotected intercourse, the failure of the contraceptive used during coitus, or rape;
- when continuing the pregnancy could be harmful or even fatal to the mother, to the foetus, or to both.
The MTP (Amendment) Act, 2021
NCERT prints a box on the law (page 46). In our words, it says that the Act was meant to reduce illegal abortion and the maternal deaths and illness that follow it; that a pregnancy may be terminated on certain grounds within the first 12 weeks on the opinion of one registered medical practitioner; that between 12 and 24 weeks, two registered medical practitioners must be of that opinion, formed in good faith; and that the grounds are (i) a risk to the life of the pregnant woman or of grave injury to her physical or mental health, or (ii) a substantial risk that the child, if born, would suffer from such physical or mental abnormalities as to be seriously handicapped.
NCERT slip (page 46): the box names the law as the “Medical Termination of Pregnancy (Amendment) Act, 2017”. The amending Act is the Medical Termination of Pregnancy (Amendment) Act, 2021, Act No. 8 of 2021, published in the Gazette of India on 25 March 2021. The box’s 24-week outer limit matches it, but its 12-week limit for one practitioner does not. In our own words, the Act as amended allows a registered medical practitioner to terminate a pregnancy:
- up to 20 weeks, on the opinion of one registered medical practitioner;
- from 20 to 24 weeks, only for categories of women prescribed by rules, on the opinion of at least two registered medical practitioners;
- in either case if continuing the pregnancy would risk the woman’s life or gravely injure her physical or mental health, or if there is a substantial risk that the child, if born, would suffer from a serious physical or mental abnormality (the Act’s 2021 wording; NCERT’s box says “seriously handicapped”);
- up to 20 weeks, the anguish of a pregnancy that follows the failure of a contraceptive device or method used by the woman or her partner may be presumed to be a grave injury to her mental health; for a pregnancy she alleges was caused by rape, it is presumed so, up to 24 weeks;
- the week limits do not apply where termination is needed because a Medical Board has diagnosed a substantial foetal abnormality.
Additional safeguards and exception: the Act protects the woman’s identifying information from unauthorised disclosure. Consent is required under section 3(4), with specified guardian-consent rules for those under 18 or covered by the Act’s mental-illness provision. Section 5 makes an exception to gestational-limit and two-practitioner requirements when a registered practitioner considers termination immediately necessary to save the woman’s life.
Sources: India Code, MTP Act sections 3–5A, and the 2021 amendment. NCERT’s box is not a statement of current legal thresholds. In a question on NCERT’s box, give 12 weeks (one practitioner) and 12–24 weeks (two); in a question on the 2021 Act, or on the law today, give 20 weeks (one) and 20–24 weeks (two, for prescribed categories). The 12 weeks of first-trimester safety (below) is about risk, not about how many practitioners the law requires.
Safety in the first trimester
MTPs are considered relatively safe during the first trimester, i.e., upto 12 weeks of pregnancy.
NCERT Biology (Class 12), Section 3.3, page 46
- NCERT adds that second trimester abortions are much more risky (page 46).
- Beyond the NCERT text: risk generally increases with gestational duration, but abortion can be safe beyond 12 weeks when the method, skills and setting are appropriate. WHO’s fact sheet says abortion is safe when a trained person uses a method suited to how far the pregnancy has gone (WHO, “Abortion”), so it is wrong to say that abortion is safe only before 12 weeks.
- Clinical trimester boundaries differ from NCERT’s shorthand; see pregnancy dating.
- NCERT calls it a disturbing trend that a majority of the MTPs are performed illegally by unqualified quacks, which are not only unsafe but could be fatal too (page 46). NCERT says that such practices, these and sex-selective MTP (below), should be avoided because they are dangerous both for the young mother and the foetus (page 47).
- Beyond the NCERT text: unsafe abortion can cause serious injury or death (WHO, “Abortion”); legal status and clinical safety are different concepts.
Sex-selective MTP and female foeticide
- Another dangerous trend is the misuse of amniocentesis to determine the sex of the unborn child; frequently, if the foetus is found to be female, MTP follows. This is totally against the law (page 46).
- Sex selection violates legal protections and sex equality. This is distinct from abortion undertaken for lawful medical grounds.
- Effective counselling on avoiding unprotected coitus and on the risks of illegal abortions, together with more health care facilities, could reverse these unhealthy trends (page 47).
Solved examples
Example 1: Spontaneous abortion (NCERT Exercise 11 a)
True or false, with explanation: abortions could happen spontaneously too.
Answer: true. NCERT defines MTP as the intentional or voluntary termination of a pregnancy, also called induced abortion (NCERT page 46); “induced” separates it from abortions that are not intended. NCERT also lists abortions among the complications of untreated sexually transmitted infections (page 47), which are not induced.
Example 2: NCERT’s numbers
NCERT says about 45 to 50 million MTPs a year are 1/5th of all conceived pregnancies. Roughly how many pregnancies a year does that imply?
Answer: 45 million × 5 = 225 million and 50 million × 5 = 250 million, so roughly 225 to 250 million pregnancies a year (from NCERT page 46).
Example 3: Why limits and early MTP
How should NCERT’s first-trimester safety statement be distinguished from the law and from later abortion care?
Answer: NCERT emphasises lower risk earlier in pregnancy (page 46), but 12 weeks is not the general legal limit. Later abortion can also be safe with appropriate care. The amended Act has distinct 20/24-week provisions and specific exceptions; sex selection is separately prohibited.
Common mistakes to avoid
Common mistake
Confusing “induced” and spontaneous abortion
MTP is the intentional termination of pregnancy, an induced abortion (NCERT page 46); NCERT also lists abortions among the complications of untreated STIs (page 47), and those are not induced.
Common mistake
Quoting the Act’s year as 2017
The amending Act is the MTP (Amendment) Act, 2021 (Act No. 8 of 2021); NCERT’s box prints 2017 (NCERT page 46).
Quick revision summary
- MTP (induced abortion): intentional or voluntary termination of pregnancy before full term; legalised in India in 1971 with strict conditions.
- NCERT: 45 to 50 million MTPs a year worldwide, 1/5th of conceived pregnancies; WHO’s newer estimate is about 73 million, 29 per cent of pregnancies.
- Reasons: unwanted pregnancy (unprotected intercourse, contraceptive failure, rape) or danger to the mother or foetus.
- MTP (Amendment) Act, 2021: up to 20 weeks with one practitioner; 20–24 weeks for prescribed categories with two; no week limit where a Medical Board diagnoses a substantial foetal abnormality. NCERT’s box prints 2017 and 12/24 weeks.
- Risk depends on gestational duration, method and care; safe care is not restricted to 12 weeks. Sex selection is illegal, while the MTP Act permits abortion on specified grounds and includes an emergency life-saving exception.
Formula sheet
- MTP = induced abortion
- legalised in India: 1971
- earlier care generally has lower risk; safe care is not limited to 12 weeks
- 2021 Act: up to 20 weeks one practitioner; >20–24 weeks two, for prescribed categories; exceptions apply
Questions students ask
How did the 2021 amendment change India’s MTP Act?
Beyond the NCERT text, the 2021 amendment mainly raised the week limits: under the original Act one registered medical practitioner’s opinion sufficed up to 12 weeks and two were needed from 12 to 20 weeks (MoHFW guidance, 2015), whereas now one suffices up to 20 weeks and two are needed from 20 to 24 weeks, a window open only to categories of women the rules prescribe (Gazette of India, 2021). The contraceptive-failure ground, once limited to a married woman or her husband, now covers any woman or her partner. Two provisions are new: no week limit where a Medical Board diagnoses a substantial foetal abnormality, and a bar on practitioners revealing a woman’s identity.
Who is allowed to perform an MTP in India, and where?
Beyond the NCERT text, India’s MTP Act lets only a registered medical practitioner end a pregnancy, at a Government hospital or a place approved by the Government or its District Level Committee, though in an emergency to save the woman’s life an unapproved place is allowed (MoHFW guidance, 2015). Not every doctor qualifies: the practitioner needs the training or experience in gynaecology and obstetrics that the rules lay down, on top of a recognised medical qualification and a name on a State Medical Register (MoHFW, 2015). Since the 2021 amendment, rules also set which practitioners may give the opinion at each stage of pregnancy (Gazette of India, 2021).
What is the difference between female foeticide and female infanticide?
Female foeticide is the killing of a female foetus before birth, while female infanticide, a term from beyond the NCERT text, is the killing of a baby girl after birth: MeSH defines infanticide as “the killing of infants at birth or soon after”. NCERT discusses only foeticide, which it reports to be high in India and which the strict conditions on MTP are meant to help check (page 46). The ban on using tests to learn a foetus’s sex is explained with amniocentesis.
Is MTP a method of contraception?
No, MTP is not a method of contraception: contraceptive methods prevent a pregnancy from starting, and NCERT’s list of them, from natural and barrier methods to surgical ones, does not include MTP (page 43), while MTP is the termination of a pregnancy that has already begun (page 46). Even emergency contraception, which NCERT places among contraceptive methods, is used soon after coitus to avoid a possible pregnancy (page 45), not to end one. Beyond the NCERT text, the MTP (Amendment) Act, 2021 likewise treats termination as ending an existing pregnancy, with medicines or by surgery (Gazette of India, 2021).

Q1. In which year did the Government of India legalise MTP?
Show answerHide answer
1971 (NCERT page 46).
-
Q2. What interval does NCERT call relatively safe, and does it mean later care is always unsafe?
Show answerHide answer
NCERT names up to 12 weeks (page 46). This emphasises earlier lower risk; later abortion is not inherently unsafe when appropriate methods and care are available.
-
Q3. Why is the use of amniocentesis followed by MTP of a female foetus against the law?
Show answerHide answer
Amniocentesis is meant to test for genetic disorders; using it to find the sex of the foetus and then terminating a female foetus is sex-selective abortion, which is illegal and is checked by the statutory ban on amniocentesis for sex determination (NCERT pages 42 and 46).
