NCERT Solutions for Class 12 Biology Chapter 4 – Reproductive Health

 

1. What do you think is the significance of reproductive health in a society?

Reproductive health is crucial for the well-being of individuals and the overall development of society. It ensures:

  • Awareness about safe and hygienic sexual practices
  • Prevention and control of sexually transmitted infections (STIs)
  • Reduced maternal and infant mortality rates
  • Family planning and population control
  • Overall improvement in the quality of life

2. Suggest the aspects of reproductive health which need to be given special attention in the present scenario.

Key aspects needing focus include:

  • Sexual education and awareness in schools
  • Access to contraceptives and family planning services
  • Awareness and prevention of STIs and HIV
  • Proper maternal and child health care
  • Combating female foeticide and ensuring gender equality

3. Is sex education necessary in schools? Why?

Yes, sex education is necessary in schools because it:

  • Removes myths and misconceptions about sex and sexuality
  • Promotes safe sexual practices and reproductive health
  • Helps prevent STIs and unwanted pregnancies
  • Develops respect for gender differences and equality

4. Do you think that reproductive health in India has improved in the past 50 years? If yes, mention some such areas of improvement.

Yes, reproductive health in India has improved significantly:

  • Decline in infant and maternal mortality rates
  • Better awareness about family planning and contraceptives
  • Increased access to maternal health services
  • Promotion of institutional deliveries and immunisation
  • Government initiatives like RCH (Reproductive and Child Health) Programme

5. What are the suggested reasons for population explosion?

Population explosion is mainly due to:

  • Decline in death rate, infant mortality rate, and maternal mortality rate
  • Better medical facilities and health awareness
  • Lack of education and awareness about family planning
  • Early marriage and large family norms

6. Is the use of contraceptives justified? Give reasons.

Yes, the use of contraceptives is justified because:

  • They help control population growth
  • Prevent unwanted pregnancies
  • Reduce maternal and infant health risks
  • Help space out births and improve family health

7. Removal of gonads cannot be considered as a contraceptive option. Why?

Removal of gonads (testes/ovaries) leads to permanent loss of reproductive and hormonal function. It is not a contraceptive method but a surgical sterilisation that has severe physiological consequences and is not ethically or medically acceptable as contraception.

8. Amniocentesis for sex determination is banned in our country. Is this ban necessary? Comment.

Yes, the ban is necessary to prevent female foeticide, which leads to an imbalance in sex ratio. Misuse of amniocentesis for sex determination has been a major cause of declining female birth rates, and banning it helps promote gender equality.

9. Suggest some methods to assist infertile couples to have children.

Methods to help infertile couples include:

  • In vitro fertilisation (IVF – test tube baby)
  • Zygote intra fallopian transfer (ZIFT)
  • Gamete intra fallopian transfer (GIFT)
  • Intra cytoplasmic sperm injection (ICSI)
  • Artificial insemination (AI)

10. What are the measures one has to take to prevent contracting STDs?

Preventive measures include:

  • Maintaining monogamous relationships
  • Avoiding multiple sexual partners
  • Use of condoms during intercourse
  • Prompt medical consultation in case of symptoms
  • Regular health check-ups and education about STDs

11. State True/False. Correct the false statements.

  • (a) Abortions could happen spontaneously too. (True)
  • (b) Infertility is defined as the inability to produce viable offspring and is always due to abnormalities in the female partner. (False – Infertility can be due to issues in male, female, or both)
  • (c) Complete lactation could help as a natural method of contraception. (True)
  • (d) Creating awareness about sex-related matters is an effective method to improve reproductive health. (True)

12. Correct the following statements:

  • (a) Surgical methods of contraception prevent gamete formation.

    Correction: Surgical methods prevent gamete transport, not formation.
  • (b) All sexually transmitted diseases are completely curable.

    Correction: Not all STDs are curable; viral infections like HIV are not.
  • (c) Oral pills are very effective contraceptives and can be taken without any medical advice.

    Correction: Oral pills should be taken under medical supervision.
  • (d) In E.T. techniques, embryos are always transferred into the uterus.

    Correction: Embryos may be transferred into the fallopian tubes or uterus depending on the stage.
