2.0NCERT Class 12 Biology Chapter 3 Reproductive Health : Detailed Solutions
What do you think is the significance of reproductive health in a society?
Ans. In a society if the people are aware of birth control methods to avoid sexually transmitted diseases and the importance of breast-feeding and post-natal care of the mother and baby then the society can have healthy children who are the future citizens of a nation.
Suggest the aspects of reproductive health which need to be given special attention in the present scenario?
Ans. Important aspects :
Counselling and creating awareness among people especially the youth about various aspects of reproductive health such as sexually transmitted diseases, available contraceptive methods, case of pregnant mothers, adolescence etc.
Providing support and facilities such as medical assistance to people during pregnancy, STIs, abortions, contraceptives, infertility, etc. for building a reproductively healthy society.
Is sex education necessary in schools? Why?
[IMP.]
Ans. Yes, sex education is necessary in schools because
It will provide proper information about reproductive organs, adolescence, safe, hygienic sexual practices and sexually transmitted infection (STIs).
It will provide right information to avoid myths and misconceptions about sex related queries.
Do you think that reproductive health in our country has improved in the past 50 years? If yes, mention some such areas of improvement.
Ans. Yes, the reproductive health has tremendously improved in India in the last 50 years. The areas of improvement are as follows.
Batter awareness about sex related matters.
Increase number of medically assisted deliveries and better post natal care of child and mother leading to decrease maternal and infant mortality rate.
Increase numbers of couples with small families.
Better detection and cure of STIs and overall increased medical facilities for all sex related problems.
What are the suggested reasons for population explosion?
Ans. The suggested reasons of population explosion are:
(a) rapid decline in death rate.
(b) decline in maternal mortality rate (MMR)
(c) decline in infant mortality rate (IMR) and
(d) increase in number of people in reproducible Age
Is the use of contraceptives justified? Give reasons.
Ans. Yes, the use of contraceptives is absolutely justified. The human population is increasing tremendously. Therefore to regulate the population growth by regulating reproduction has become a necessary demand in the present times. Various contraceptive devices have been devised to reduce unwanted pregnancies which help in bringing down the increased birth rate and hence, in checking population explosion.
Removal of gonads cannot be considered as a contraceptive option. Why?
Ans. The removal of gonads not only stops the production of gametes but will also stop the secretion of various important hormone which required for body functions. This method is irreversible and thus, cannot be considered as a contraceptive method.
Amniocentesis for sex determination is banned in our country. Is this ban necessary? Comment.
[IMP.]
Ans. Yes, this ban is necessary because amniocentesis is misused for determining the sex of the foetus and then aborting the child if it is a female.
Suggest some methods to assist infertile couples to have children.

Specialized health care units called infertility clinics could help in diagnosis and corrective treatment of some of these disorders. Through special techniques called assisted reproductive technologies (ART), infertile couple could be assisted to have children.
ART includes:
(i) In vitro fertilisation,
(ii) Gamete intra fallopian transfer (GIFT),
(iii) Intra cytoplasmic sperm injection (ICSI), and
(iv) Artificial insemination (AI).
What are the measures one has to take to prevent from contracting STDs? [IMP.]
Ans. Sexually transmitted Infection (STIs) get transferred from one individual to the other through sexual contact. Adolescents and young adults are at the greatest risk of acquiring these sexually transmitted diseases. Hence,
Creating awareness among the adolescents regarding its after-effects can prevent them from contracting STIs.
The use of contraceptives such as condoms etc. while intercourse can prevent the transfer of these diseases.
Sex with unknown partners or multiple partners should be avoided as they may have such diseases.
Specialists should be consulted immediately in case of doubt so as to assure early detection and cure of the disease.

(a) Surgical methods of contraception prevent gamete formation.
(b) All sexually transmitted diseases are completely curable.
(c) Oral pills are very popular contraceptives among the rural women.
(d) In E. T. techniques, embryos are always transferred into the uterus.
Ans.
(a) Surgical method of contraception prevents gamete motility.
(b) All sexually transmitted diseases are curable if they are detected early and treated properly. AIDS is still an incurable disease.
(c) Oral pills are very popular contraceptives among urban women.
(d) In embryo transfer technique, 8 celled embryos are transferred into the fallopian tube while more than 8 celled embryos are transferred into the uterus.
