Answer:
The following reproductive health areas need extra focus:
Making sure that the right information regarding reproductive organs, STDs, AIDS, and safe sex is available.
Informing individuals about means of birth control, prenatal checkups for pregnant women, and postnatal care for mother and infant.
As per latest 2024 syllabus. Maths formulas, equations, & theorems of class 11 & 12th chapters
Question 3. Is sex education necessary in schools? Why?
Answer:
Yes, school sex education is necessary because:
Teenagers need to study reproductive organs, the changes which come with puberty, safe sexual activities, and STDs during adolescence.
It enhances awareness concerning methods of birth control and inculcates an understanding of healthful reproduction.
Educating school students means there will be an educated and more reproductively healthy community.
Answer:
Yes, reproductive health has also improved a lot in the last 50 years because of several initiatives:
Family planning schemes were initiated as early as 1951.
Reproductive Health awareness campaigns are carried out through media and NGOs.
Maternal and infant mortality rates have come down dramatically.
Female foeticide has been curbed by prohibiting amniocentesis for sex determination.
Mass immunization drives for infants and children have been undertaken.
Question 5. What are the suggested reasons for the population explosion?
Answer:
The reasons for population growth are:
Substantial reduction of death rates, maternal death rate, and child death rate.
Increase in population in the childbearing age.
Better medical infrastructure increases life spans.
Illiteracy leads to unawareness regarding birth control mechanisms.
Question 6. Is the use of contraceptives justified? Give reasons.
Answer:
Yes, the use of contraceptives is justified because:
The increasing population can result in shortages of basic resources such as food, shelter, and healthcare.
Contraceptives effectively and safely control population growth without side effects when used properly.
Contraceptive methods are simple to use, inexpensive, and readily available.
Question 7. Removal of gonads cannot be considered as a contraceptive option. Why?
Answer:
Gonad removal is not a contraceptive because:
It causes permanent sterility by totally stopping gamete production.
It also ceases the production of hormones required for the proper functioning of accessory reproductive organs.
Question 8. Amniocentesis for sex determination is banned in our country. Is this ban necessary? Comment.
Answer:
Yes, amniocentesis for sex determination should be banned because:
The procedure was being used to detect the sex of the foetus resulting in female foeticide.
The ban reduces gender-based abortions and supports gender equality.
Question 9. Suggest some methods to assist infertile couples to have children.
Answer:
Infertile couples may be treated by various assisted reproductive technologies (ART), which include:
IVF (In-vitro Fertilization) followed by subsequent embryo transfer (ET), commonly known as the test-tube baby technique.
GIFT (Gamete Intrafallopian Transfer): In-vivo fertilized embryos are implanted in the fallopian tube of a recipient female.
AI (Artificial Insemination): Used when there is an insufficient number of sperms; sperms are artificially introduced into the female's uterus or vagina.
ICSI (Intracytoplasmic Sperm Injection): One sperm is injected into an ovum directly to form an embryo.
Question 10. What are the measures one has to take to prevent from contracting STDs?
Answer:
To avoid sexually transmitted diseases (STDs), do the following:
Practice the use of condoms during sex regularly and properly.
Stay away from sexual activity with unfamiliar or multiple sex partners.
Practice good sexual hygiene and see a doctor in case of symptoms.
Question 11. State True/False with an explanation
(a) Abortions could happen spontaneously too. (True/False)
Answer:
(a) Abortions could happen spontaneously too.
True, abortion which is medical termination of pregnancy can happen spontaneously too.
Answer:
(b) Infertility is defined as the inability to produce viable offspring and is always due to abnormalities/defects in the female partner.
False. Male partners could also be responsible for infertility.
Question 11. (c) Complete lactation could help as a natural method of contraception. (True/False)
Answer:
(c) Complete lactation could help as a natural method of contraception.
True. During complete lactation, no ovulation takes place so no menstrual cycle and no chances of fertilization.
Answer:
(d) Creating awareness about sex related aspects is an effective method to improve the reproductive health of the people.
True. Creating awareness about sex-related aspects is an effective method to improve the reproductive health of people.
Question 12. Correct the following statements :
(a) Surgical methods of contraception prevent gamete formation
Answer:
Surgical methods of contraception do not prevent gamete formation. They act as a contraceptive by not allowing the transfer of gametes, thus preventing unwanted pregnancies.
(b) All sexually transmitted diseases are completely curable.
Answer:
Some sexually transmitted diseases are completely curable if detected earlier. Aids is a sexually transmitted disease which is still incurable.
(c) Oral pills are very popular contraceptives among rural women.
Answer:
Oral pills are very popular contraceptives among urban women.
(d) In ET techniques, embryos are always transferred into the uterus.
Answer:
In the ET technique, an embryo of 8 cell stage or lesser is transferred to the fallopian tube while that of more than 8 blastomere stage is transferred to the uterus.
NCERT Solutions for Class 12: Subjectwise
Here is a key question that will help you focus on important concepts and strengthen your understanding for the exams.
Question 1: Diaphragms are contraceptive devices used by females. Choose the correct option from the statements given below:
i. They are introduced into the uterus.
ii. They are placed to cover the cervical region.
iii. They act as physical barriers to sperm entry.
iv. They act as spermicidal agents.
Options
i and ii
i and iii
ii and iii
iii & iv
Answer:
Diaphragms are categorized as barrier contraceptives for females. Their function is to obstruct pregnancy by being positioned in the vagina, where they cover the cervix. This placement prevents sperm from moving into the uterus. They serve as physical obstacles that hinder sperm from reaching the egg, thereby diminishing fertilization likelihood.
The inaccurate statements are as follows:
i. Insertion into the uterus is not correct. Diaphragms are vaginal devices that cover the cervix, not placed within the uterus itself.
iv. Diaphragms are not inherently spermicidal. Although they can be used with spermicides, which are chemicals that eliminate sperm, the diaphragms on their own are barriers, not agents of sperm destruction. The spermicide is an additional component applied to the diaphragm for enhanced contraceptive properties.
Hence, the correct answer is option 3), (ii) and (iii)

Reproductive health, as defined in NCERT Class 12 Biology, refers to a state of complete physical, mental, and social well-being in all matters related to the reproductive system. It emphasizes that reproductive health is not merely the absence of diseases or disorders but includes the capability to reproduce and the freedom to make informed choices regarding reproduction. Key components include:
Physical Well-being: Individuals should have a healthy reproductive system, free from diseases and disorders.
Mental Well-being: Emotional stability and psychological readiness for reproduction are essential.
Social Well-being: Access to healthcare, education, and support systems plays a crucial role in reproductive health.
The concept also highlights the importance of reproductive rights and the need for access to comprehensive healthcare services that address reproductive health needs effectively
Major reproductive health problems include:
Infertility: Addressed through assisted reproductive technologies like IVF and counselling for couples.
Sexually Transmitted Infections (STIs): Prevention through education, access to condoms, and regular screenings.
Unplanned Pregnancies: Managed by promoting contraceptive use and family planning services.
Reproductive Health in Organisms class 12 NCERT Solutions involves enhancing access to healthcare services, education on reproductive rights, and community awareness programs.
The Indian government promotes reproductive health through various initiatives:
Family Planning Programs: Expanding contraceptive options and ensuring access to family planning services.
Awareness Campaigns: Educating the public about reproductive health, STIs, and contraception.
Healthcare Services: Providing comprehensive primary healthcare services as per the National Health Policy 2017.
Adolescent Health Programs: Initiatives like Rashtriya Kishor Swasthya Karyakram focus on the sexual and reproductive health needs of adolescents
NCERT Class 12 Biology outlines several contraceptive methods:
Barrier Methods: Includes male and female condoms, diaphragms, and cervical caps that physically block sperm from entering the uterus.
Intrauterine Devices (IUDs): Devices inserted into the uterus that prevent fertilization or implantation.
Hormonal Methods: Oral contraceptive pills containing progestogens or estrogen combinations taken daily to prevent ovulation.
Surgical Methods: Permanent solutions like tubectomy or vasectomy
STDs can significantly impact reproductive health by causing complications such as:
Pelvic Inflammatory Disease (PID): Untreated STDs can lead to PID, resulting in scarring of the fallopian tubes and infertility.
Epididymitis in Men: STDs can cause inflammation of the epididymis, affecting sperm transport.
Overall, untreated STDs can lead to long-term fertility issues for both men and women
Amniocentesis is a prenatal diagnostic procedure used to detect genetic abnormalities by analyzing amniotic fluid. Its role in reproductive health includes:
Genetic Screening: Helps identify conditions such as Down syndrome or spina bifida early in pregnancy.
The controversy surrounding amniocentesis stems from ethical concerns regarding selective abortion based on test results, potential risks of miscarriage associated with the procedure, and issues related to informed consent
Improving reproductive health in developing countries can be achieved through:
Access to Education: Providing comprehensive sex education to empower individuals with knowledge about their reproductive rights.
Healthcare Infrastructure: Strengthening healthcare systems to ensure the availability of contraceptives and maternal care services.
Community Engagement: Involving local communities in awareness campaigns about reproductive health issues and available services
Changing from the CBSE board to the Odisha CHSE in Class 12 is generally difficult and often not ideal due to differences in syllabi and examination structures. Most boards, including Odisha CHSE , do not recommend switching in the final year of schooling. It is crucial to consult both CBSE and Odisha CHSE authorities for specific policies, but making such a change earlier is advisable to prevent academic complications.
