NEET Biology Reproductive Health 2027 is one of the highest-yield Class 12 Unit-2 chapters. NTA’s NEET pattern consistently includes 4–6 questions from this chapter — covering RCH programmes, contraception, MTP Act, infertility methods (ART), and STIs. This guide gives NCERT-aligned notes plus 40 chapter-wise practice MCQs.
Chapter Overview — NCERT Class 12 Chapter 4
- Total weightage in NEET Biology: 4–6 questions
- NCERT pages: ~14
- Concept density: moderate-high
- Diagram requirements: minimal (mainly contraceptive devices, ART techniques)
1. Reproductive Health — Definition and Significance
WHO defines reproductive health as a state of complete physical, mental, social and emotional well-being in all matters relating to the reproductive system, its functions and processes. India was the first country to launch a national programme — the Reproductive and Child Health (RCH) programme.
2. Reproductive Health Problems and Strategies
| Problem | Strategy/Programme | Year of Launch |
|---|---|---|
| Population explosion | Family planning, IEC programmes | 1951 (first country) |
| STIs/STDs | Awareness, condom use, NACO | 1992 (NACO) |
| Female feticide | PCPNDT Act | 1994 (amended 2003) |
| Maternal mortality | Janani Suraksha Yojana, ASHA workers | 2005 |
| Infertility | ART centres, surrogacy regulation | 2021 (Surrogacy Act) |
3. Population Stabilisation and Birth Control
India’s population stabilisation effort relies on family planning. Birth control = preventing unwanted pregnancy. Common methods:
3.1 Natural Methods
- Periodic abstinence — avoid coitus from day 10 to 17 of menstrual cycle
- Withdrawal/Coitus interruptus
- Lactational amenorrhea — works up to 6 months post-partum, only if mother breastfeeds exclusively
3.2 Barrier Methods
- Condoms (male/female) — also prevent STIs/HIV
- Diaphragms, cervical caps, vaults
3.3 IUDs (Intrauterine Devices)
- Non-medicated: Lippes loop
- Copper-releasing: CuT, Cu-7, Multiload-375
- Hormone-releasing: Progestasert, LNG-20
3.4 Oral Contraceptive Pills
- Saheli — non-steroidal, weekly pill, developed by CDRI Lucknow
- Combined OCP — estrogen + progesterone
3.5 Injectables and Implants
Progesterone alone or progesterone + estrogen, lasting 3 months to several years.
3.6 Surgical/Permanent Methods
- Vasectomy (males) — vas deferens cut/tied
- Tubectomy (females) — fallopian tubes cut/tied
3.7 Emergency Contraception
Within 72 hours of unprotected coitus — progestogen or progestogen-estrogen combination, or IUDs.
4. Medical Termination of Pregnancy (MTP)
Legalised in India in 1971, amended in 2021. Key MTP Act 2021 provisions for NEET:
- Allowed up to 20 weeks on opinion of one registered medical practitioner (RMP)
- 20–24 weeks: opinion of two RMPs (for special categories — survivors of rape, minors, women with disabilities)
- Beyond 24 weeks: only on Medical Board approval, for substantial fetal abnormalities
- Confidentiality of woman’s identity protected
5. Sexually Transmitted Infections (STIs)
| STI | Causative Organism | Curable? |
|---|---|---|
| Gonorrhoea | Neisseria gonorrhoeae (bacteria) | Yes |
| Syphilis | Treponema pallidum (bacteria) | Yes |
| Chlamydiasis | Chlamydia trachomatis | Yes |
| Trichomoniasis | Trichomonas vaginalis | Yes |
| Genital herpes | Herpes simplex virus | No (manageable) |
| Genital warts | Human papillomavirus (HPV) | No (vaccine available) |
| HIV/AIDS | Human immunodeficiency virus | No (ART manages) |
| Hepatitis B | HBV | No (vaccine prevents) |
Hepatitis B and HIV transmit not just sexually but also via shared needles, contaminated blood, infected mother to child.
6. Infertility and Assisted Reproductive Technology (ART)
| Technique | Full Form | Process |
|---|---|---|
| IVF | In Vitro Fertilisation | Ova + sperm fused outside body, zygote/early embryo transferred |
| ZIFT | Zygote Intra Fallopian Transfer | Zygote (with up to 8 blastomeres) transferred into fallopian tube |
| IUT | Intra Uterine Transfer | Embryo (more than 8 blastomeres) transferred into uterus |
| GIFT | Gamete Intra Fallopian Transfer | Ovum (from donor) transferred into fallopian tube of woman who cannot produce one |
| ICSI | Intra Cytoplasmic Sperm Injection | Sperm directly injected into ovum |
| AI | Artificial Insemination | Semen introduced into vagina/uterus |
