In India, family planning programmes were initiated in 1951 at a national level to attain total reproductive health as a social goal. According to World Health Organization (WHO), reproductive health means total well-being of an individual in the physical, social behavioural and emotional aspects of reproduction "Saheli', an oral contraceptive pill for the females was developed by scientists at Central Drug Research Institute (CDRI) in Lucknow. Amniocentesis is being misused to determine the sex of the foetus and kill the normal female foetuses. Therefore, it should be legally banned to avoid female foeticide

Rapid increase in population over a relatively short period of time is called population explosion. Reasons for population explosion are increased health facilities, decrease in MMR (maternal mortality rate), and IMR (infant mortality rate) and increase in number of people reaching reproductive age.

- I - F (IVF): In vitro fertilization (IVF) involves the collection of gametes and their fertilization in the laboratory to form a zygote.
- II - B (ZIFT): Zygote intra-fallopian tube transfer (ZIFT) involves transferring a zygote or early embryo (up to 8 blastomeres) into the oviduct.
- III - E (IUT): Intrauterine transfer (IUT) involves transferring a zygote with more than 8 blastomeres into the uterus.
- IV - H (In-vivo fertilization): Fusion of gametes within the female, which is the natural process of fertilization.
- V - A (GIFT): Gamete intra-fallopian tube transfer (GIFT) involves transferring ovum from a donor to the oviduct of the recipient.
- VI - D (ICSI): Intracytoplasmic sperm injection (ICSI) involves injecting sperm directly into the ovum in vitro.
Thus, the correct match is: I - F, II - B, III - E, IV - H, V - A, VI - D.

Incorrect Statements:
(i) Condoms decrease sperm motility.
(ii) Diaphragms, cervical caps and vaults are for both males and females.
Explanation:
- Condoms, when used correctly, are highly effective in preventing pregnancy. They act as a barrier method, preventing sperm from reaching the egg. They do not decrease sperm motility but rather prevent sperm from entering the vagina. Therefore, statement (i) is incorrect.
- Diaphragms, cervical caps, and vaults are contraceptive devices that are designed to be used by females. They are inserted into the vagina to cover the cervix and prevent sperm from entering the uterus. These devices are not designed for use by males. Therefore, statement (ii) is incorrect.
Correct Statements:
(iii) IUDs are inserted by expert nurses.
(iv) Sterilisation is a terminal method to prevent further pregnancy.
Explanation:
- Intrauterine devices (IUDs) are small, T-shaped devices that are inserted into the uterus to prevent pregnancy. While they can be inserted by healthcare professionals, including doctors and nurses, it is not limited to expert nurses only. Therefore, statement (iii) is correct.
- Sterilization is a permanent method of contraception that involves the surgical blocking or sealing of the fallopian tubes in females or the vas deferens in males. It is a highly effective method of preventing further pregnancies. Therefore, statement (iv) is correct.
Conclusion:
The option that contains both incorrect statements is option (b) - (i) and (ii). Condoms do not decrease sperm motility, and diaphragms, cervical caps, and vaults are not designed for use by males.

Lead Academy answered |
The most effective strategy for addressing myths and misconceptions about reproductive health among adolescents is to integrate sex education into school curricula and support it with community-based programs. This approach ensures that accurate information is provided in a structured educational environment and reinforced through various media channels and community efforts. Solely focusing on disease prevention, relying on informal dissemination, or enforcing regulations without educational support would not be as comprehensive in fostering a well-informed and healthy society.

Meera Singh answered |
Abortions could occur spontaneously too. The reason for this could be any physiological problem in the mother or foetus or both. During complete lactation, there is no ovulation and thus chances of conceiving are nil or less during this period. Creating awareness about reproduction by audio-visual and print media, governmental and non-governmental agencies help in creating a reproductively healthy society. Infertility is the inability to produce viable offspring due to defects in either male or female or both the partners.

In-vitro fertilization technique essentially involves the fusion of ovum and sperm outside the body of the female. The zygote is allowed to develop in-vitro and embryo with 6-8 blastomere is transferred into the uterus. the baby thus developed is called test tube baby.
(i) In IVF, ova from the wife/donor female and sperm from the husband/donor male are induced to form zygote in the test-tube or in-vitro.
(ii) Embryo with 2 blastomeres is not transferred into the uterus. It is allowed to develop.
(iii) If the embryo has achieved 6-8 blastomeres, it is tranferred into the uterus for implantation.
(iv) The baby thus developed is called the test tube baby.

Explanation:
The given paragraph talks about the natural methods of contraception that can be used by couples to avoid unwanted pregnancy. These methods do not involve the use of any artificial devices or medications but work on the principles of avoiding chances of ovum and sperm meeting or abstaining from sexual activity during certain periods of the menstrual cycle.
(i) Barrier methods involve the use of physical barriers such as condoms, diaphragms, or cervical caps to prevent the sperm from reaching the egg.
(ii) Coitus interruptus involves the withdrawal of the penis from the vagina just before ejaculation to prevent the release of sperm into the vagina. This method is not very reliable as it requires a lot of self-control and can be difficult to practice consistently.
(iii) Periodic abstinence involves tracking the menstrual cycle and avoiding sexual activity during the fertile period, which is typically between days 10 to 17 of the menstrual cycle. This method requires a lot of discipline and awareness of one's menstrual cycle.
(iv) Lactational amenorrhea method is based on the fact that breastfeeding can suppress ovulation and delay the return of menstruation after childbirth. This method is only effective if the mother is exclusively breastfeeding and has not yet resumed menstruation.
In conclusion, natural methods of contraception can be effective for couples who are looking for non-invasive and hormone-free options for birth control. However, these methods require a lot of self-discipline and awareness of one's body and menstrual cycle. It is important to consult a healthcare provider to discuss which method is best suited for individual needs and circumstances.

Mohit Rajpoot answered |
- (a) Using unsterile surgical instruments: STIs can be spread through unsterile surgical instruments if they are contaminated with infected blood or bodily fluids. So, this option is not correct for our answer.
- (b) Infected mother to foetus: STIs can be transmitted from an infected mother to the foetus during pregnancy or childbirth. So, this option is not correct for our answer.
- (c) Kissing: Most STIs are not spread through kissing. Kissing is generally not a mode of transmission for most STIs, except for some, like herpes simplex virus (HSV), which can cause oral herpes. However, for the purpose of this question, kissing is considered generally non-transmissive for STIs.
- (d) Inheritance: STIs are not inherited. They are transmitted through direct contact with infected bodily fluids or through specific modes of transmission, not through genetic inheritance.
- (e) Transfusion of blood from infected persons: STIs can be spread through blood transfusion if the blood is contaminated with the virus. So, this option is not correct for our answer.
- (f) Using sterile needles: Using sterile needles does not transmit STIs. Proper sterilization of needles prevents transmission. So, this option is correct for our answer.
- (g) Infected foetus to mother: The transmission of STIs from an infected foetus to the mother is not a typical mode of infection. The usual mode is from mother to foetus, not the reverse. Therefore, this option is correct for our answer.
Thus, the correct options where STIs cannot spread are (c) Kissing, (d) Inheritance, (f) Using sterile needles, and (g) Infected foetus to mother, which makes Option 2 the correct answer.

Ruchi Singh answered |
How IUDs prevent pregnancy:
Intrauterine devices (IUDs) are a highly effective form of contraception that prevent pregnancy through a few different mechanisms.
Inhibiting physiological and morphological uterine changes:
- One way IUDs prevent pregnancy is by inhibiting the physiological and morphological changes in the uterus that are required for implantation of a fertilized egg. The presence of the IUD in the uterus creates a hostile environment for implantation to occur, making it difficult for a fertilized egg to attach to the uterine lining.
Increasing phagocytosis of spermatozoa within the uterus:
- Another way IUDs prevent pregnancy is by increasing the phagocytosis of spermatozoa within the uterus. This means that the IUD helps the body's immune system to more effectively engulf and destroy sperm cells, reducing the chances of fertilization taking place.
Suppressing motility of sperms as well as their fertilizing capacity:
- IUDs also work by suppressing the motility of sperm and reducing their fertilizing capacity. This makes it harder for sperm to reach and fertilize an egg, further reducing the likelihood of pregnancy.
Combination of mechanisms:
- Overall, IUDs prevent pregnancy through a combination of inhibiting uterine changes required for implantation, increasing phagocytosis of sperm, and suppressing sperm motility and fertilizing capacity. This multi-faceted approach makes IUDs one of the most effective forms of contraception available.

A population explosion in India is influenced by factors such as a decline in death rates, maternal mortality rates, and infant mortality rates, which contribute to an increased population due to improved survival rates. However, a decline in the number of people in the reproductive age group would actually reduce the potential for population growth, making it an incorrect factor contributing to population explosion.

Lactational amenorrhea (absence of menstruation) method is based on the fact that ovulation and therefore the cycle do not occur during the period of intense lactation following parturition. Therefore, as long as the mother breastfeeds the child fully, chances of conception are almost nil. However, this method has been reported to be effective only upto a maximum period of six months following parturition. As no medicines or devices are used in these methods, side effects are almost nil.

Multiload device contains Copper.
Explanation:
The Multiload device is a type of intrauterine device (IUD) used for contraception. It is a small, T-shaped device that is inserted into the uterus to prevent pregnancy. The device is made of a combination of materials, but the primary component is copper.
Copper is chosen as the main material for the Multiload device because of its contraceptive properties. When the device is inserted into the uterus, the copper ions released from the device create a toxic environment for sperm. This prevents the sperm from reaching and fertilizing the egg, thereby preventing pregnancy.
The effectiveness of the Multiload device as a contraceptive method is primarily due to the presence of copper. The copper ions released by the device have both spermicidal and inflammatory effects. The spermicidal effect immobilizes and damages the sperm, while the inflammatory effect creates a hostile environment for the sperm, preventing fertilization.
Other materials may also be present in the Multiload device for structural support and ease of insertion, but copper is the key component responsible for its contraceptive action.
In conclusion, the correct answer is option 'C' - Copper. The Multiload device contains copper as its primary component, which is responsible for its contraceptive properties.

Mira Joshi answered |
In test tube baby or in vitro fertilisation technique, the ovum is fertilised with the sperm outside the body of a woman providing the ovum with the same environmental conditions as it would have got inside the uterus. The zygote formed is grown inside a culture and when embryo (having 8 or more blastomeres) is formed, it is then implanted into uterus where it develops into foetus.

Surgical (sterilisation) methods of contraception prevent pregnancy by blocking gamete transport and hence their fertilisation. Surgical method in male is called vasectomy and in female, it is called tubectomy. Both methods are very effective but their reversibility is very poor. They are generally regarded as terminal methods to prevent any more pregnancies.

Statement I is true because abortions can occur spontaneously due to natural causes. Statement III is true as lactational amenorrhea can act as a natural contraceptive method during breastfeeding. Statement IV is also true as creating awareness is essential for promoting reproductive health. Statement II is false because infertility can result from factors affecting either the male or female partner.

Figure (c) is of vasectomy which is a surgical contraception method performed in males. In vasectomy, a small part of the vas deferens is removed or tied up through a small cut on the scrotum. This prevents sperm transport. Vasectomy has a poor reversibility. There is no effect on libids and erectile functioning.

Figure R is showing complete blockage of Fallopian tubes and figure S is showing tubectomy which is a surgical method of contraception in females. When both the Fallopian tubes are blocked or cut and tied, there will be no transport of gametes and thus no fertilisation.

Gaurav Kumar answered |
Figure (d) is of hormone implants. These are six matchstick-sized capsules containing synthetic progesterone which are implanted subcutaneously under the skin of the inner arm above the elbow. The capsules slowly release the progesterone for about five years. This blocks ovulation (by inhibiting the release of FSH and LH from pituitary) and thickens the cervical mucus to prevent sperm transport.

Inability to conceive or produce children even after unprotected sexual intercourse is called infertility. Specialised infertility clinics can help in diagnosis and proper treatment of infertile couples. But, when such treatment is not possible, the couples can be assisted to have children through certain special techniques called assisted reproductive technologies (ART).
