Class 12 Biology Chapter 3 covers Reproductive Health, a stable 5 to 7 mark contributor in CBSE boards and a 2 to 4 question topic in NEET. Students revising RCH programmes, contraceptive methods, ART acronyms and STIs will find the official chapter here. This page hosts the verified 2026-27 NCERT PDF for Reproductive Health Chapter 3.
- CBSE Weightage: 5-7 marks within the Reproduction unit (Sections A, B and C of the Class 12 Biology paper).
- NEET Weightage: 2-4 questions consistently across recent NEET papers from the Human Reproduction unit.
- CUET Weightage: 3-4 MCQs from the Reproductive Health domain section.
Why Reproductive Health Matters across CBSE, NEET and CUET
Reproductive Health sits at the intersection of biology, public-health policy and adolescent education. That is why CBSE rarely drops a question from this chapter and why NEET examiners reuse its definitions across paper sets. The NCERT framing follows the WHO definition of reproductive health as "total well-being in all aspects of reproduction" and builds out to RCH programmes, contraception, MTP, STIs and the assisted reproductive technologies.
Across NEET 2023, 2024 and 2025, Reproductive Health contributed at least two questions per year. CBSE board papers since 2021 have asked at least one 3-mark or 5-mark long answer from this chapter. Most questions come from contraceptive methods or ART (IVF, ZIFT, GIFT, ICSI).

Sections Inside the Reproductive Health NCERT Chapter
Chapter 3 is divided into five sections that begin with public-health framing and end with technologies for infertility. The section sequence mirrors the official ncert.nic.in reprint exactly.
| Section | Topic | Key NCERT Terms |
|---|---|---|
| 3.1 | Reproductive Health: Problems and Strategies | RCH programme, sex-education, amniocentesis ban |
| 3.2 | Population Stabilisation and Birth Control | Natural methods, IUDs, Saheli, surgical methods |
| 3.3 | Medical Termination of Pregnancy (MTP) | MTP Act 1971, first and second trimester |
| 3.4 | Sexually Transmitted Infections (STIs) | Gonorrhoea, syphilis, AIDS, hepatitis-B |
| 3.5 | Infertility and Assisted Reproductive Technologies | IVF, ZIFT, GIFT, ICSI, IUI, AI |
CBSE almost always lifts the 3-mark question from Section 3.2 or 3.5. NEET prefers fact-recall MCQs from Sections 3.4 and 3.5.
Important Topics in Reproductive Health for Class 12 Biology Boards and NEET
The five most-asked topics from Chapter 3 across CBSE Boards 2025, NEET 2025 and CUET UG 2025 are listed below. Use this list to prioritise revision in the last week before the exam.
| Topic | Why it Matters | Frequent Exam Format |
|---|---|---|
| Contraceptive methods (Natural, Barrier, IUDs, Oral, Surgical) | NCERT classifies in five clean buckets | 3-mark short answer / NEET MCQ |
| Saheli oral contraceptive | Indian-origin non-steroidal once-a-week pill | 1-mark MCQ / Assertion-Reason |
| Assisted Reproductive Technologies (IVF, ZIFT, GIFT, ICSI, IUI) | Full-form recall and procedure differences | 5-mark long answer (CBSE) |
| MTP Act and amniocentesis misuse | Bio-ethics and Indian legal framework | 2-mark short answer / CUET stem |
| Sexually Transmitted Infections (STIs) | Causal organism and symptom matching | NEET MCQ / CUET MCQ |
In NEET 2025, three of the four Human Reproduction questions came from Sections 3.2 and 3.5. A focused re-read of these two sections delivers high-return revision in under 50 minutes.
Reproductive Health PYQ Trend across CBSE Boards 2021-2025
The five-year board paper trend shows that Chapter 3 has been a stable 5 to 7 mark contributor. The chapter usually appears as one short answer and one MCQ or assertion-reason pair, not a single long answer alone.
| Year | Marks Carried | Most-Asked Sub-Topic |
|---|---|---|
| 2025 | 7 | ART (IVF, ZIFT, GIFT) full-form and procedure |
| 2024 | 5 | Contraceptive methods: classification |
| 2023 | 6 | MTP Act 1971 and amniocentesis misuse |
| 2022 | 6 | STIs: causal organisms and symptoms |
| 2021 | 5 | RCH programme and population stabilisation |

Exam Comparison: How Reproductive Health Appears across Major Exams
Chapter 3 carries different weightage profiles across CBSE, NEET and CUET. The last three held editions of each exam are shown so the pattern reflects current paper design.
| Exam | 2025 | 2024 | 2023 |
|---|---|---|---|
| CBSE Class 12 Biology | 7 marks | 5 marks | 6 marks |
| NEET | 3 questions | 2 questions | 3 questions |
| CUET UG Biology | 4 MCQs | 3 MCQs | 3 MCQs |
The chapter is a NEET favourite because ART-acronym matching and STI causal-organism matching slot into MCQ stems cleanly. CBSE prefers descriptive contraceptive-method and MTP-Act questions in the 3 and 5 mark slots.

What NCERT Kept in the 2026-27 Edition of Chapter 3
The 2026-27 NCERT reprint of Class 12 Biology retains every section of Reproductive Health from the previous edition. There is no rationalised content drop in this chapter. Students preparing from older PDFs will find Sections 3.1 through 3.5 numbered identically. The Saheli paragraph, MTP Act 1971 reference and the ART acronyms are all present.
