Reproductive Health — Short Notes

WHO defines reproductive health as complete physical, mental, behavioural, and social well-being related to reproduction.

India's Reproductive Health Initiatives

  • Family Planning started in 1951 — first country to launch a national programme.
  • RCH (Reproductive and Child Health Care) Programmes — current umbrella: awareness, counselling, sex education, prenatal & post-natal care.
  • Goals: safe motherhood, low IMR & MMR, universal knowledge of contraception, control of STDs, prevention of amniocentesis misuse for sex determination.

Population Explosion & Birth Control

  • India's population: > 1 billion (~1.7 billion projected); rapid decline in death rate + high birth rate.
  • Contraception — measures to prevent unwanted pregnancy. Ideal contraceptive: user-friendly, reversible, few side effects, no interference with intercourse.

Contraceptive methods

MethodHow it worksExamples
Natural / behaviouralAvoid sperm–ovum contactRhythm (periodic abstinence), coitus interruptus, lactational amenorrhoea (up to 6 months post-partum)
BarrierPhysical blockCondoms (Nirodh, femidom), diaphragm, cervical cap, vault
IUDsPrevent implantation, phagocytose sperm, thicken cervical mucusNon-medicated (Lippes loop), Cu-releasing (CuT, Cu7, Multiload), hormone-releasing (Progestasert, LNG-20)
OralSuppress ovulation, alter uterine liningCombined pill (Mala D, Mala N — daily), Saheli (weekly, non-steroidal)
Injectables / implantsLong-acting progestinsInjections, subcutaneous implants
EmergencyPost-coital, within 72 hProgestin / IUD insertion
Surgical (sterilisation)TerminalVasectomy (males), Tubectomy (females)

Medical Termination of Pregnancy (MTP)

  • Legalised in India in 1971; amended 2017/2021.
  • Reasons: unwanted pregnancy (contraceptive failure, rape), risk to mother, foetal abnormality.
  • Safe up to 12 weeks; risky in second trimester.
  • Misuse: illegal sex-selective abortion — banned by PC-PNDT Act.

Sexually Transmitted Diseases (STDs)

  • Also called VD/RTI. Common ones: gonorrhoea, syphilis, genital herpes, chlamydiasis, genital warts, trichomoniasis, hepatitis-B, HIV/AIDS.
  • Curable: gonorrhoea, syphilis, chlamydiasis, trichomoniasis if treated early.
  • Not curable (as of NCERT): genital herpes, hepatitis-B, HIV/AIDS.
  • Prevention: avoid multiple partners, use condoms, use disposable needles, seek treatment early.

Infertility

  • Inability to conceive after 1+ year of unprotected regular sex. Causes may be male, female, or genetic/psychological.

Assisted Reproductive Technologies (ARTs)

TechniqueWhat it does
IVF-ET (test-tube baby)Ovum + sperm fused in lab → 8-cell stage → ZIFT (fallopian tube) or 16+ cell → IUT (uterus)
ZIFTZygote Intra-Fallopian Transfer
IUTIntra-Uterine Transfer
GIFTGamete Intra-Fallopian Transfer (for women who can't produce ova)
ICSIIntra-Cytoplasmic Sperm Injection (single sperm injected into ovum)
AI (Artificial Insemination)Sperm placed into female tract; also IUI (Intra-Uterine Insemination)

Amniocentesis

  • Foetal cell sampling via amniotic fluid — detects genetic disorders (Down's syndrome, haemophilia, sickle-cell anaemia).
  • Misused for sex determination → led to female foeticide → banned for sex determination in India.

Take-aways

  • Reproductive health is not just absence of disease — it includes physical, mental, and social well-being.
  • Population control needs contraception + counselling + late marriage + small-family norm.
  • STDs, infertility, and unsafe abortions are major public-health concerns addressed by RCH programmes.
