Short Answer Questions
Question. An infertile couple is advised to adopt test-tube baby programme. Describe two principle procedures adopted for such technologies.
Ans. (i) IVF/In vitro fertilisation: It is the fertilisation of gametes outside the body in almost similar conditions as that in the body.
(ii) ET/Embryo transfer: Embryos formed by fusion of gametes is transferred into reproductive tract or uterus.
Question. After a brief medical examination a healthy couple came to know that both of them are unable to produce functional gametes and should look for an ‘ART’ (Assisted Reproductive Technique). Name the ‘ART’ and the procedure involved that you can suggest to them to help them bear a child. [CBSE Delhi 2015]
Ans. Test tube baby programme can be done.
(i) Test Tube Baby Programmes
• In this method, ova from the wife/donor (female) and the sperms from the husband/donor (male) are collected and induced to form zygote under simulated conditions in the laboratory.
This process is called in vitro fertilisation (IVF).
• The zygote or early embryo with up to 8 blastomeres is transferred into the fallopian tube (process is called zygote intra fallopian transfer or ZIFT) and if embryo with more than 8 blastomeres is
transferred into the uterus (process is called intra uterine transfer or IUT).
• In females who cannot conceive, embryos formed by fusion of gametes in another female (called in vivo fertilisation) are transferred.
Question. The process of GIFT involves the transfer of female gamete to the fallopian tube. Can gametes be transferred to the uterus to achieve the same result? Explain.
Ans. The uterine environment is not congenial for the survival of the gamete. If directly transferred to the uterus, they will undergo degeneration or could be phagocytosed and hence viable zygote would not be formed.
Question. How can childless couples be helped by the following assisted reproductive technologies:
(a) GIFT? (b) Intracytoplasmic Sperm Injection?
Ans. (a) GIFT (Gamete Intra Fallopian Transfer): It is the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce one, but can provide suitable environment for fertilisation and further development.
(b) Intracytoplasmic Sperm Injection (ICSI): It is a process in which an embryo is formed in the laboratory, in which a sperm is directly injected into the ovum.
Question. What do you think is the significance of reproductive health in a society?
Ans. In a society, if 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.
Question. Suggest the aspects of reproductive health which need to be given special attention in the present scenario.
Ans. (i) Introduction of sex education in school that helps in eradicating myths and misconceptions regarding sex-related aspects.
(ii) Proper information about reproductive organs, safe and hygienic sexual practices and sexually transmitted diseases (STDs).
(iii) Awareness of problems due to uncontrolled population growth, social evils like sex-abuse and sex-related crimes, etc.
(iv) Strong infra-structural facilities, professional expertise and material support to provide medical assistance and care to people in reproduction-related problems.
(v) Educating people about available birth control options, care of pregnant mothers, post-natal care of mother and child, importance of breast-feeding, equal opportunities for the male and female child.
Question. Is sex education necessary in schools? Why?

• Early symptoms: Itching, fluid discharge, slight pain and swellings in the genital region.
• Complications due to chronic STDs: Pelvic inflammatory diseases (PID), abortions, still births, ectopic pregnancies, infertility, or even cancer of the reproductive tract.
• Transmission of hepatitis-B and HIV also occurs by the following ways:
(i) Sharing of injection needles or surgical instruments with infected persons;
(ii) transfusion of infected blood;
(iii) transfer from infected mother to the foetus through placenta.
Question . Name two hormones that are constituents of contraceptive pills. Why do they have high and effective contraceptive value? Name a commonly prescribed non-steroidal oral pill.

Ans. (a) IUD—Intra uterine devices.
(b) Hormone releasing IUDs are considered a good contraceptives because
(i) they make the uterus unsuitable for implantation.
(ii) they increase the phagocytosis of sperms within uterus and the Cu ions released, suppress sperm motility and the fertilising capacity of sperms.
Question . Name three incurable sexually transmitted diseases and their causative organisms.
Ans. Sexually transmitted disease Causal agent
(i) Hepatitis-B Hepatitis-B virus
