CBSE Class 12 Biology – Reproductive Health
NCERT-aligned chapter resource | Biology Code 044
1. Meaning and Need
Reproductive health refers to total well-being in matters related to the reproductive system. It includes awareness, responsible behaviour, prevention and treatment of reproductive disorders, and access to appropriate healthcare.
2. Population and Reproductive Health
Education about reproduction helps people understand puberty, contraception, sexually transmitted infections, pregnancy and responsible reproductive choices. Public-health programmes aim to reduce maternal and infant mortality and improve reproductive outcomes.
3. Contraceptive Methods
| Method | Examples | Principle |
|---|---|---|
| Barrier | Condom, diaphragm | Prevents sperm from reaching ovum |
| IUD | Copper-T | Creates conditions that reduce fertilisation and implantation |
| Hormonal | Oral pills | Suppress ovulation and alter reproductive conditions |
| Surgical | Vasectomy, tubectomy | Blocks reproductive ducts |
4. Medical Termination of Pregnancy
MTP refers to intentional termination of pregnancy under medical supervision. The chapter emphasises safe, regulated healthcare rather than unsafe procedures.
5. Sexually Transmitted Infections
STIs include infections such as gonorrhoea, syphilis, genital herpes, chlamydiasis and HIV/AIDS. Prevention includes responsible behaviour, appropriate protection, awareness, testing and timely medical treatment.
6. Infertility and Assisted Reproductive Technologies
Infertility can arise from male, female or combined factors. Techniques discussed include IVF followed by embryo transfer, ZIFT and GIFT. Their use depends on the underlying cause and medical advice.
7. Why Awareness Matters
Reproductive-health education reduces misinformation and supports informed decisions. It should include respect, consent, hygiene, prevention and access to qualified healthcare.
