In many countries, sexual education raises much contentious debate. Chief among the controversial points is whether covering child sexuality is valuable or detrimental; the use of birth control such as condoms and hormonal contraception, and the impact of such use on pregnancy, outside marriage, teenage pregnancy, and the transmission of STDs. Increasing support for abstinence – only sex education by conservative groups has been one of the primary causes of the controversies.
4. 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, in the last 50 years, reproductive health in our country has improved. Some such areas of improvement are (i) massive child immunization (ii)maternity and child health (iii) increasing use of contraceptives (iv) family planning.
Bringing sexual and reproductive health services to the millions of people living in countries which still suffer from short life expectancies, high levels of child and maternal mortality, child lSS&ur and illiteracy and poor overall health remains a major challenge for governments and non government organizations.

5.What are the suggested reasons for population explosion?
Ans.(i) Increased health facilities along with better living conditions had an explosive impact on the growth of population.
(ii)Decline in Death rate
(iii)Decline in Maternal Mortality Rate
(iv)Decline in Infant Mortality Rate
(v)Increase in the number of people in the reproductive age.

6.Is the use of contraceptives justified? Give reasons.
Ans. Yes, the use of contraceptives is justified: To overcome the population growth rate, contraceptive methods are used. It will help in bringing birth rate down & subsequently curb population growth. With the rapid spread of HIV/ AIDS in the country, there is now a growing realization about the need to know about contraceptions & condoms.

7. Removal of gonads cannot be considered as a contraceptive option. Why?
Ans. Removal of gonads or its parts is a surgical method ,of sterilization. Vasectomy and tubectomy are carried out in males and females respectively. It will lead to infertility & both male and female will be dependent on hormones in their remaining life to regulate functioning of reproductive organs. These are very effective but their irreversibility is very poor, so they are not good options for contraception.

8.Amniocentesis for sex determination is banned?in our country. Is this ban necessary? Comment
Ans. Since Amniocentesis is misused to find out the sex of the foetus leading to female foeticides, it is necessary. It is the prenatal diagnostic
technique, that helps to find out chromosomal (genetic) disorders, metabolic disorders of the foetus; in extreme cases where the foetus is found to be suffering from an incurable disorder Medical Termination of Pregnancy (MTP) is banned. The solution to the problem is not ‘ passing more laws, such as banning sex determination ultrasounds but raising the social & economic status of women.

9. Suggest some methods to assist infertile couples to have children.
Ans. ART (Assisted Reproductive Technologies) is a term that describes several different methods used to help infertile couples. ART involves removing eggs from a woman’s body, mixing them with sperm in the laboratory and putting the embryos bath into a woman’s body.
Success rates vary depending on many factors.Something that affects the success rate of ART includes age of the partners, reason for infertility,type of ART, if the egg is fresh or frozen. Various methods are now available to help such couples are — in vitro fertilization, gamete intra fallopian transfer, intracytoplasmic sperm injection & artificial insemination.
(i)In vitro fertilization – Patient’s egg & her partner’s sperm are collected & mixed together in a laboratory to achieve fertilization outside the body. The embryo produced may then be transferred into the female patient. It is commonly knownas test tube baby programme.
(ii)Gamete Intra Fallopian Transfer (GIFT) – A procedure in which eggs are retrieved from a woman, mixed with sperm & immediately replaced in one or other of the women’s fallopian tubes so that they fertilize inside the body (invivo).
(iii)Intra Cytoplasmic Sperm Injection (ICSI)– In this method, sperm & eggs are retrieved from both the parents. A single sperm is injected directly into an egg, then the fertilized egg is implanted into the woman’s uterus.
(iv)Artificial insemination – In this technique, the semen is collected either from husband or a healthy donor & is artificially introduced either into the vagina or into the uterus of the female (IUI-Intra uterine insemination).

10.What are the measures one has to take to prevent from contracting STDs?
Ans.(i) Avoiding sex with unknown partner /multiple partners.
