Reproductive Health comparison tables
1. Reproductive Health Programmes and Their Focus
Key NCERT strategies for a reproductively healthy society
AreaPurposeExamples / outcomes
Reproductive and Child Health (RCH)Awareness, facilities and support for reproductive healthMedical care for pregnancy, delivery, contraception, STIs, infertility and menstrual problems
Sex educationCorrect myths and misconceptions; encourage safe and hygienic practicesInformation on adolescence, reproductive organs, STIs and AIDS
Maternal and child carePromote healthy familiesAntenatal and post-natal care, breast-feeding, immunisation
Legal / social safeguardsPrevent misuse and sex-related social evilsBan on amniocentesis for sex determination; action against female foeticide
2. Natural, Barrier and IUD Contraceptive Methods
Methods that prevent meeting of gametes or fertilisation
MethodPrinciple / actionNCERT examples and cues
Periodic abstinenceAvoid coitus during fertile periodDays 10-17 of menstrual cycle; no medicines or devices, but failure chances are higher
WithdrawalPenis withdrawn before ejaculation to avoid inseminationAlso called coitus interruptus
Lactational amenorrhoeaIntense lactation suppresses ovulation and menstruationEffective only up to about six months after parturition when breast-feeding is complete
Barrier methodsPhysically prevent sperm and ovum from meetingMale/female condoms; diaphragms, cervical caps and vaults; condoms also reduce STI risk
Non-medicated IUDInserted into uterus by trained professionalLippes loop
Copper-releasing IUDIncreases sperm phagocytosis; copper suppresses sperm motility and fertilising capacityCuT, Cu7, Multiload 375
Hormone-releasing IUDMakes uterus unsuitable for implantation and cervix hostile to spermProgestasert, LNG-20
3. Hormonal vs Surgical Contraception
Methods acting through hormones or blocked gamete transport
FeatureHormonal methodsSurgical methods / sterilisation
FormsPills, injectables and implantsVasectomy in male; tubectomy in female
ActionInhibit ovulation and implantation; alter cervical mucus to retard sperm entryBlock gamete transport, preventing conception
ExamplesProgestogen or progestogen-oestrogen pills; Saheli is non-steroidal once-a-week pillVas deferens cut/tied in vasectomy; fallopian tube cut/tied in tubectomy
Typical useDaily pills for 21 days, beginning within first five days of cycle; repeat after 7-day breakTerminal method when no further pregnancies are desired
ReversibilityGenerally reversible under medical guidanceHighly effective, but reversibility is poor
Emergency useHormonal pills or IUDs within 72 hours of coitus can prevent possible pregnancyNot an emergency method
4. MTP vs Contraception
Prevention of pregnancy and termination of pregnancy are distinct
PointContraceptionMedical termination of pregnancy (MTP)
When usedBefore conception, to prevent unwanted pregnancy or delay/space pregnancyAfter conception, to intentionally terminate pregnancy before full term
ExamplesNatural methods, barriers, IUDs, pills, implants, sterilisationLegal procedure under specified conditions and qualified medical care
SafetyMethod should be selected with qualified medical adviceRelatively safer during first trimester (up to 12 weeks); second-trimester abortion is riskier
Important cautionPossible side effects must not be ignoredIllegal, unsafe procedures and sex-selective abortion must be avoided
5. Curable vs Non-curable STIs in NCERT
Sexually transmitted infections and prevention
GroupExamples / featuresNCERT point
Usually completely curable if detected earlyGonorrhoea, syphilis, chlamydiasis, genital warts and trichomoniasisEarly detection and complete treatment are essential
Not completely curableHepatitis-B, genital herpes and HIV infectionHIV leading to AIDS is especially dangerous
Other transmission routesHepatitis-B and HIV may spread through contaminated needles, instruments, blood transfusion and mother-to-foetus transmissionNot limited to sexual intercourse
PreventionAvoid unknown/multiple partners; use condoms; seek qualified medical help promptlySTI incidence is high in 15-24 year age group
6. Assisted Reproductive Technologies (ART)
Techniques used to assist infertile couples
TechniqueWhat is transferred / doneKey condition
IVF-ETFertilisation outside body, followed by embryo transferKnown as test-tube baby programme
ZIFTZygote or early embryo (up to 8 blastomeres) transferred to fallopian tubeZygote intra-fallopian transfer
IUTEmbryo with more than 8 blastomeres transferred to uterusIntra-uterine transfer
GIFTDonor ovum transferred to fallopian tubeRecipient cannot produce ova but can provide environment for fertilisation and development
ICSISperm injected directly into ovum in laboratoryForms embryo under specialised handling
AI / IUISemen artificially introduced into vagina or uterusUseful for inability to inseminate or very low sperm count
