CHAPTER 3: REPRODUCTIVE HEALTH
High-Yield Revision Notes for CBSE Boards & NEET Preparation
1. Reproductive Health: Problems and Strategies
According to the World Health Organisation (WHO), reproductive health signifies a total well-being in all
aspects of reproduction, including physical, emotional, behavioural, and social dimensions.
National Level Programmes
• First in the World: India was amongst the first countries in the world to initiate action plans and
programmes at a national level to attain total reproductive health as a social goal.
• Family Planning: These programmes were initiated in 1951 and have been periodically assessed over the
past decades.
• RCH Programmes: Improved programmes covering wider reproduction-related areas are currently in
operation under the popular name ‘Reproductive and Child Health Care’ (RCH) programmes.
NEET HIGH ALERT
Amniocentesis (Statutory Ban): Enforced strictly for sex-determination to curb female foeticides.
• Procedure: A small amount of amniotic fluid from the developing foetus is taken to analyze the fetal
cells and dissolved substances.
• Legitimate Use: To diagnose chromosomal or genetic disorders like Down syndrome, haemophilia,
and sickle-cell anemia to assess fetal survivability.
Saheli Oral Pill: A unique oral contraceptive for females developed by scientists at the Central Drug
Research Institute (CDRI) in Lucknow, India. It is a non-steroidal, ‘once a week’ pill with extremely
high contraceptive value and minimal side effects.
2. Population Stabilisation and Birth Control
Demographic Explosion Metrics
• Global Trend: The world population was ~2 billion (2000 million) in 1900, rocketed to 6 billion by 2000,
and reached 7.2 billion in 2011.
• National Trend (India): ~350 million at independence, crossed the 1 billion mark in 2000, and reached 1.2
billion in May 2011.

, • Core Triggers: A rapid decline in Death Rate, Maternal Mortality Rate (MMR), and Infant Mortality
Rate (IMR) alongside an expanded population of reproducible age.
• Growth Scale: According to the 2011 census, the growth rate was less than 2% (i.e., 20/1000/year), a
rate sufficient to cause acute resource scarcity.
Characteristics of an Ideal Contraceptive
An ideal birth control method must be user-friendly, easily available, highly effective, completely reversible with
no or minimal side effects, and must not interfere with sexual drive or performance.
3. Categories of Contraceptive Methods
A. Natural / Traditional Methods
Work entirely on the medical principle of avoiding the physical intersection of the ovum and sperm.
• Periodic Abstinence: Couples completely avoid or abstain from coitus from day 10 to 17 of the
menstrual cycle (the designated fertile window when ovulation is highly expected).
• Withdrawal / Coitus Interruptus: The male partner withdraws the penis from the vagina right before
ejaculation to prevent insemination.
• Lactational Amenorrhea: Based on the biological absence of menstruation during intense post-partum
lactation. Ovulation does not occur during this cycle phase. Maximum effective duration is 6 months
post-delivery; failure rates are relatively high.
B. Barrier Methods
Mechanical blockades preventing gametes from physically meeting.
• Condoms: Disposable, thin rubber/latex sheaths. Popular male brand is ‘Nirodh’. Uniquely provide
additional protection against STIs and AIDS.
• Diaphragms, Cervical Caps, & Vaults: Reusable rubber barriers inserted into the female reproductive
tract to securely block the cervix during coitus. Frequently paired with spermicidal creams/foams to
increase efficacy.
