Reproductive Health class 12 notes

INTRODUCTION

  • Definition:-
    According to WHO. reproductive health means a total well being in all aspects of reproduction, emotional, social and behavioural.

  • Key components of reproductive health:-

    (i) Access to Information and Education: Access to accurate and comprehensive information about reproductive anatomy, physiology, contraception, sexually transmitted infections (STIs), and family planning methods is essential for making informed decisions about sexual and reproductive health.

    (ii) Maternal and Newborn Health: Ensuring access to quality maternal and newborn health care services, including prenatal care, skilled attendance at childbirth, postnatal care, and neonatal care, promotes safe motherhood and reduces maternal and infant mortality and morbidity.

    (iii) Infertility Prevention and Treatment: Addressing infertility issues through early detection, diagnosis, and treatment options can help individuals and couples achieve their reproductive goals and improve their overall well-being.

    (iv) Prevention of Gender-based Violence: Efforts to prevent and respond to gender-based violence, including sexual assault, intimate partner violence, and harmful traditional practices, are crucial for promoting reproductive autonomy, bodily integrity, and overall well-being.

    (v) Reproductive Rights: Recognizing and upholding reproductive rights, including the right to make autonomous decisions about one’s body, sexuality, reproduction, and family formation, is essential for ensuring that individuals can exercise control over their reproductive lives free from discrimination, coercion, and violence.

    Note:- Overall, reproductive health is a fundamental component of overall health and well-being, with implications for individual dignity, human rights, gender equality, and sustainable development. It encompasses a holistic approach to sexual and reproductive well-being that encompasses physical, emotional, social, and cultural dimensions.

POPULATION STABILISATION

  • According to 2011 census report, our population growth rate was less than 2 percent i.e 20/1000/year.

    Year          World Population                   Indian Population
    1900         2 billion                                    350 million
    2000         6 million                                   1 billion 
    2011         7.2 billion                                 1.2 billion 
  • Reasons For increase in Population Size:-
    • Decline in death rate.
    • Rapid decline in maternal mortality rate (MMR).
    • Decrease in infant mortality rate (IMR).
    • Increase in number of people in reproducible age.
    • Increase in health facilities.
  • Measures Taken By Government To Check Population Growth Rate.  
    • Motivate-smaller families by using various contraceptive methods with slogans Hum do Hamare do” advertisements and posters.
    • Urban couples adopting: “One child norm” 
    • 
    Statutory raising of marriageable age:
                    Female to 18 years          • Male to 21 years
    • Incentives given to coupes with small families.

                           

BIRTH CONTROL/CONTRACEPTION

  • Features of an ideal contraceptive:
    • 
    User-friendly
    • Easily available
    • Effective 
    • Reversible
    • No/least side-effects
    • No interference with libido and act of coitus
  • There are two principle methods of birth control:
    Natural methods
    • Artificial methods 

REPRODUCTIVE HEALTH: PROBLEMS AND STRATEGIES

  • India was amongst the first countries in the world to initiate action plans to attain total reproductive health such as family planning programmes (FPP) in 1951.
  • Tasks performed by “Reproductive and Child Health care (RCH) programmes.”

    • Helping adolescents by providing information about reproductive organs hygienic sexual practices and STls. 
    Awareness regarding social evils such as sex-abuse and sex related crimes.
    • Importance of equal opportunities for male and female child.
    • Educating the people about birth control options 
    Benefits of families with small size.
    • Introduction of sex education in schools.
    • Benefits of massive child immunisation.
    • Role of NGOs, 
    audio-visual and print media in creating awareness regarding sex related aspects.
    Discouraging children from believing in myths and having misconceptions about sex related aspects.
    • Creating awareness about care of pregnant mother, post natal care of mother and child.
    • 
    Importance of breast feeding.

REPRODUCTIVE HEALTH-SEX EDUCATION

NATURAL/TRADITIONAL METHODS

  • Work on the principle of avoiding physical meeting of the egg and sperms.
  • Chances of failure are high.

       Method                                  Mode of Action (MoA)
    • Periodic-abstinence
    :          Couples abstain from coitus from day
                                                       10 to 17 of the menstrual cycle
                                                       i.e fertile period.
    • Withdrawal method/ :          Insemination is avoided as the male 
      Coitus interruptus                partner withdraws his penis from the 
                                                       vagina just prior to ejaculation.
    • Lactational amenorrhea     Absense of menstruation upto  6 months
                                                       during period of intense lactation
                                                       following parturition.

MEDICAL TERMINATION OF PREGNANCY (MTP)/INDUCED ABORTION

  • MTP:- Intentional or voluntary termination of pregnancy before full term.
  • MTP was legalised in India in 1971.
  • When can MTP be performed?
    > Unwanted preganancy due to rape, failure of contraception, casual unprotected intercourse.
    If continuation of pregnancy could harm the mother or foetus or both
    > Permission of how many medical practitioners is needed for MTP depending on duration of gestation

AMNIOCENTESIS

  • Analyse fetal cells and dissolved substances from amniotic fluids.
  • Technique used to check for genetic disorders such as Down’s syndrome, hemophilia, sickle-cell anemia etc.
  • Statutory ban on this technique in India to prevent female foeticide.

    > preventive measures to avoid STIs:-
        • Avoid sex with unknown partners/ multiple partners.
        • Always try to use condoms during coitus.




     

INFERTILITY

  • Infertile couple: Unable to produce children inspite of 2 years of unprotected sexual co-habitation.
