REPRODUCTIVE HEALTH

• It is the state of physical, emotional,

behavioral and social fitnessfor leading a
reproductive life.

• According to WHO: A total well-

being in all aspects of reproduction,
i.e., physical, emotional, behavioral
and social.
Reproductive Health- Problems &
Strategies :-

 India was among the 1st countries to initiate

actions & plans to attain total reproductive
health as social goal.

 These programs are called as ‘FAMILY

PLANNING’-initiated in 1951.

 Improved programs covering reproduction

related areas are in operation- ‘Reproductive &
Child Health Care Programs’ (RCH).

 Create awareness about various reproduction

aspects & provide facilities and support to build
reproductively healthy society.
HOW HAS THE GOVERNMENT TAKEN
MEASURES?
• Through the help of audio-visuals &
print media to create awareness.
• Family members, close relations are involved in
the awareness.
• Sex education is introduced in schools to
provide awareness
• Proper information about reproductive
organs, adolescence &related changes,
safe & hygienic sexual practices, sexually
transmitted diseases (STD), AIDS etc.
• Educating people about birth control options,
care of pregnant women, post- natal care of
mother & child, importance of breastfeeding,
equal importance to both male & female
child- socially conscious healthy family
• Awareness of uncontrolled population growth,
social evils- build socially responsible healthy
society.
• Implementation of various action plan
requires infrastructural facilities,
professional expertise & material support
to provide medical assistance and care to
people in reproduction related problems,
pregnancy, delivery, STDs, abortions,
contraception, menstrual problems,
infertility etc.
• Statutory ban on Amniocentesis- legally check
female foeticide, massive child immunisation-
programs.
• Researches on reproduction related areas,
supported by gov. &non- governmental
agencies to improve/ find new methods
upon the existing ones. Saheli
(Contraceptive)- Central Drug Research
Institute (CDRI)
• Improved reproductive healthy society-
increased medically assisted deliveries,
better post natal care, decreased maternal &
infant mortality rate, small families, better
detection & cure of STDs- increased facilities
for sex related problems.
POPULATION EXPLOSION AND BIRTH
CONTROL

• The increase in size and growth of human

population is calledpopulation explosion.
• Indian population- 350 million at
independence and crossed 1billion in May
2000
• Alarming growth rate- scarcity of basic
requirements (food, shelter& clothing)
• The reason for high population explosion are:
1. Decline in death rate.
2. Longer life span.
3. Decline in maternal mortality rate (MMR)
4. Decline in infant mortality rate (IMR)
5. Some religious belief against birth control.
6. Lack of reproductive health knowledge.
• Some steps to overcome population explosion:

1. Motivate smaller families using contraceptive

methods

2. Awareness through media, posters/ bills-

Hum Do Hamare Do(we two, our two)

3. Couples mostly young, urban, working ones

adopted ‘one childnorm’

4. Statutory raising of marriageable age, female- 18,

male- 21

5. Incentives to couples with small families

6. Contraceptive methods, to prevent unwanted

pregnancies
 CONTRACEPTION
• Contraception aims to control birth, by using
contraceptives
• Prevention of conception or fertilization of ovum
during sexual intercourse is called contraception.
• An ideal contraceptive should be user- friendly,
easily available,
effective and reversible with no or least side
effects.
• The different types of contraceptives are:
1. Natural / Traditional method
2. Barrier method
3. Intra uterine device [IUD’s]
4. Oral contraceptives
5. Injection and implants
6. Surgical method
Natural methods:

• It work on the principle of avoiding chances of

ovum and sperms
meeting.
a) Periodic abstinence:
• Is a method in which couple avoid or abstain
coitus form day 10 to 17of the menstrual cycle
when ovulation could be expected.
b) Withdrawal or coitus interruptus:
• In this method male partner withdraws his
penis from the vagina justbefore ejaculation
to avoid insemination.
c) Lactational amenorrhea:
• Based on fact that ovulation/cycle absent
during intense lactationfollowing
parturition. Hence chance of fertilization is
absent.
• Effective for 6 months, side effects are nil
• Chances of failure are high.
Physical contraceptive or Barrier methods:

• This method prevents contact of sperm and

ovum by barrier.
• Available for both male and female.
a) Condoms:
• Barriers made of thin rubber/ latex sheath, self-
inserted & disposable.
• Covers penis in male & vagina and cervix in
female. It is used so thatsemen does not
enter the female reproductive tract.
• It also prevents AIDS and STDs.
b) Diaphragm, cervical caps and vaults:
• Barrier, made of rubber latex.
• Inserted into the female reproductive tract to
cover the cervix
• Block entry of sperm through cervix, reusable
• Spermicidal cream, jellies, foams along with
these barriers
 Intra Uterine Devices (IUDs)

• These devices are only used by female

• Inserted by doctor or nurses
in the uterus through
vagina.
• They are available as:
a) Non-medicated IUDs
e.g. Lippes loop: Phagocytosis of sperm
b) Copper releasing IUDs (CuT, Cu7,Multiload
375):
• Cuion released suppresses spermmotility and
fertilizing capacity ofsperm.
• IUDs increases phagocytosis of sperm
within the uterus.
3) Oral contraceptives:
• Oral administration of small doses of
progesterone or progesterone-estrogen
combination
• Female, tablets & so called pills, taken daily for
a period of 21 days
• Inhibit ovulation & implantation & alter the
quality of cervical mucusto prevent entry of
sperm
• Effective less side effects, Eg. Saheli- non
steroidal preparation, once a week PILL
4) Injections or implants:
• Progesterone alone or in combination with
estrogen used as injections or implants under
the skin of female.
• Action similar to pills, effective for long periods

• Progesterone or combination of
progesterone and estrogen orIUDs-
within 72 hours of coitus are effective
as emergency contraceptives to avoid
possible pregnancy due to rape or
unprotected intercourse.
5) Surgical methods:
• It is also called as sterilization methodadvised
to male/ female partner to prevent any future
pregnancy.
• Blocks gamete transport, thus prevent
conception
• Sterilization in male is called-vasectomy&
female- ‘tubectomy’
• Vasectomy- a small part of the vas deferens is
removed or tied up throughincision made on
scrotum
• Tubectomy- small part of fallopian tubeis
removed or tied up through incision of
abdomen/ vagina
• Highly effective, reversibility is verypoor
