REPRODUCTIVE HEALTH
WHAT IS REPRODUCTIVE HEALTH?
World Health Organisation (WHO) defines: Reproductive health is a total
well-being in all aspects of reproduction i.e., physical, emotional,
behavioural & social.



REPRODUCTIVE HEALTH: PROBLEMS AND STRATEGIES
 India initiated reproductive health programmes (family planning) in
1951.
 Wider reproduction-related areas are in operation under the
Reproductive & Child Health Care (RCH) programmes.

Such programmes deal the following:
 Give awareness about reproduction related aspects for creating a
reproductively healthy society.
 Educate people about birth control, care of pregnant mothers, post-natal
care of mother & child, importance of breast feeding, equal opportunities
for male & female child etc.
 Awareness of problems due to population explosion, social evils like sex-
abuse and sex-related crimes, etc.



Aims & needs of sex education in schools:
 To provide right information about sex-related aspects. It helps to avoid
sex-related myths and misconceptions.
 To give proper information about reproductive organs, adolescence and
related changes, safe and hygienic sexual practices, sexually transmitted
diseases (STD), AIDS etc.




POPULATION EXPLOSION & BIRTH CONTROL
 In 1900, the world population was around 2 billion (2000 million). By
2000, it rocketed to about 6 billion.
 In India, population was nearly 350 million at the time of independence.
It reached 1 billion by 2000 and crossed 1.2 billion in May 2011. It means
every sixth person in the world is an Indian.
 According to the 2011 census report, our population growth rate was
less than 2% (i.e. 20/1000/year), a rate at which our population could

, increase rapidly.
Reasons for population explosion
 Increased health facilities and better living conditions.
 A rapid decline in death rate, maternal mortality rate (MMR) and infant
mortality rate (IMR).
 Increase in number of people in reproducible age.

Impacts of population
explosion Scarcity of basic requirements (food, shelter and clothing).



Control measures
 Motivate smaller families by using contraceptive methods.
 Aware peoples about a slogan Hum Do Hamare Do (we two, our two).
Many couples have adopted a 'one child norm'.
 Statutory rising of marriageable age of females (18 years) and males (21
years).



CONTRACEPTIVE METHODS

effects, should not interfere with sexual drive, desire & sexual act.
1. Natural/Traditional methods
➤ Periodic abstinence: Avoid coitus from day 10 to 17 of the menstrual
cycle (fertile period).
➤ Coitus interruptus (Withdrawal): Withdraw penis from the vagina just
before ejaculation to avoid insemination.
➤ Lactational amenorrhea: It is the absence of menstrual cycle &
ovulation due to intense lactation after parturition. This method helps to
prevent conception. This is effective up to 6 months following parturition.
It has no side effect. But chances of failure are high.
