Reproductive Health
Class 12 · Biology
4 ideas in Class 12 Biology, explained in plain words, with games and quizzes to practise.
Goals and Programmes
Part of: Healthy Choices
Reproductive health covers physical, emotional, behavioural and social well-being. India began family planning in 1951, now widened into Reproductive and Child Health Care. Awareness, medical facilities, curbs on misuse of prenatal testing and immunisation mark progress.
Why it matters. Programme names, years and indicator logic appear in reasoning questions.
Formulas
- Family planning began in 1951
- Growth below 2 percent means 20 per 1000 per year
Key words
- Reproductive health
- : Total well-being in reproductive aspects.
- RCH programmes
- : Wider care succeeding family planning.
- Amniocentesis
- : Testing fetal cells from surrounding fluid.
- MMR and IMR
- : Mother and infant mortality measures.
Try it in two minutes
- Expand health beyond organs to social aspects.
- Order family planning to RCH.
- List three signs of improvement.

Birth Control Methods
Part of: Healthy Choices
Natural methods time or avoid gamete meeting, barriers block it, copper IUDs weaken sperm, pills stop ovulation, emergency doses act within 72 hours, and surgery ties ducts. Periodic abstinence covers days 10 to 17, pills run 21 days plus a 7-day gap, and sterilisation blocks transport permanently.
Why it matters. Mechanism matching and day-count logic dominate exam questions here.
Formulas
- Fertile period is days 10 to 17
- Pills run 21 days plus a 7-day gap
- Emergency doses act within 72 hours
Key words
- Periodic abstinence
- : Avoiding union during days 10 to 17.
- Barrier methods
- : Devices blocking gamete meeting.
- IUD
- : A uterine device weakening sperm.
- Vasectomy
- : Tying the male duct.
- Tubectomy
- : Tying the female tube.
- Emergency contraceptive
- : A dose acting within 72 hours.
Try it in two minutes
- Sort six method groups by mechanism.
- Mark days 10 to 17 on a cycle.
- Pair vasectomy and tubectomy with cut ducts.
Try at home. Explain why condoms add infection protection that pills lack.
Medical Termination of Pregnancy
Part of: Tough Decisions
MTP legally ends pregnancy on grounds like risk to the mother or serious foetal abnormality, with one medical opinion up to 12 weeks and two opinions from 12 to 24 weeks. First-trimester procedures are relatively safer; illegal procedures by unqualified persons can prove fatal. Using testing to end female pregnancies is banned misuse.
Why it matters. Week limits and opinion counts are exact-memory plus reasoning questions.
Formulas
- Up to 12 weeks needs one medical opinion
- 12 to 24 weeks needs two medical opinions
Key words
- MTP
- : Legal induced ending of pregnancy.
- First trimester
- : Up to 12 weeks, relatively safer.
- Illegal MTP
- : Unsafe ending by unqualified persons.
Try it in two minutes
- Memorise 12 and 24 week gates.
- Pair each gate with opinion count.
- Contrast safe care with illegal practice.
Try at home. Explain why early counselling matters more than late action.
STIs and Assisted Reproduction
Part of: Infection and Infertility
STIs pass through sexual contact, with early signs like itching, discharge and swelling; hepatitis-B, genital herpes and HIV are not fully curable while others are if caught early. Prevention means avoiding unknown or multiple partners, using condoms and seeking early care. ART moves gametes or embryos to the right place: ZIFT for eight or fewer cells, IUT beyond, plus GIFT, ICSI and insemination.
Why it matters. Curability splits and transfer-site cutoffs are favourite trap questions.
Formulas
- ZIFT at eight or fewer cells, IUT beyond eight
- Infertility means two years without conception
Key words
- STI
- : Infection passing through sexual contact.
- IVF
- : Fusion outside the body in a lab.
- ZIFT
- : Tube transfer at eight or fewer cells.
- IUT
- : Uterus transfer beyond eight cells.
- GIFT
- : Donor ovum placed in the tube.
- ICSI
- : Direct sperm injection into ovum.
- Infertility
- : No conception after two years of trying.
Try it in two minutes
- Split STIs into curable and not fully curable.
- Recite the prevention trio.
- Place each ART at tube or uterus.
Try at home. Explain why stigma delays treatment and worsens outcomes.
