Reproductive Health Questions in English

(B) No. Using a copper-$T$ will not provide protection from sexually transmitted diseases (STDs),as it does not act as a physical barrier to prevent the exchange of bodily fluids.
It is an intrauterine device $(IUD)$ that primarily works by preventing the implantation of the embryo in the uterus and inhibiting sperm motility.
To prevent STDs,barrier methods like condoms must be used.

(N/A) Contraceptive methods are broadly classified into the following types:
$1$. $Natural \ methods$: These involve avoiding the meeting of sperm and ovum. For example, the periodic abstinence method involves avoiding sexual intercourse from day $10$ to $17$ of the menstrual cycle, as ovulation is expected during this period, making the chances of fertilization high.
$2$. $Barrier \ methods$: These prevent the physical meeting of sperm and ovum using barriers. Examples include condoms, which are thin rubber coverings for the penis in males or the vagina in females.
$3$. $Oral \ contraceptives$: These involve taking tablets or drugs orally. They contain small doses of hormones that prevent the release of eggs (ovulation), thereby preventing fertilization.
$4$. $Intrauterine \ devices \ (IUDs)$: Devices like the $Copper-T$ or loops are placed in the uterus to prevent pregnancy.
$5$. $Surgical \ methods$: These are permanent methods used to block gamete transfer. $Vasectomy$ involves blocking the $vas \ deferens$ in males to prevent sperm transfer. $Tubectomy$ involves blocking the $fallopian \ tubes$ in females to prevent the egg from reaching the uterus.

(D) Contraceptive methods are adopted for the following reasons:
$(i)$ To prevent unwanted pregnancies by avoiding fertilization.
$(ii)$ To control the population growth rate by limiting the number of births.
$(iii)$ To prevent the transmission of sexually transmitted diseases (STDs) such as $HIV$,syphilis,and gonorrhea.

(C) Sexually Transmitted Diseases $(STDs)$ are infections that are primarily spread through sexual contact.
$Syphilis$,$HIV-AIDS$,and $Gonorrhoea$ are well-known examples of $STDs$.
$Hepatitis$ (specifically $Hepatitis-B$) can be transmitted sexually,but the term '$Hepatitis$' generally refers to inflammation of the liver,which can be caused by various factors including viral infections (like $Hepatitis-A$,which is transmitted through contaminated food or water) or alcohol consumption.
Therefore,among the given options,$Hepatitis$ is the most appropriate answer as it is not exclusively or primarily classified as an $STD$ in the same category as the others.

(C) Mechanical barriers,such as condoms,act as a physical shield that prevents sperm from reaching the egg,thereby effectively preventing pregnancy.
Additionally,these barriers provide a protective layer that prevents the transmission of sexually transmitted infections $(STIs)$ during sexual intercourse.

(N/A) The various methods to avoid pregnancy (contraception) include:
$(i)$ Barrier methods (e.g.,condoms) to prevent physical contact between sperm and egg.
$(ii)$ Chemical methods (e.g.,oral pills) which change the hormonal balance of the body to prevent the release of an egg (ovulation).
$(iii)$ Intrauterine devices (e.g.,copper $T$ or loop) which are placed in the uterus to prevent implantation.
$(iv)$ Surgical methods (e.g.,vasectomy in males or tubectomy in females) which block the vas deferens or fallopian tubes respectively.
Elaboration of Chemical Method (Oral Pills):
Oral contraceptive pills contain specific hormones that inhibit the release of eggs from the ovaries. By preventing ovulation,the sperm has no egg to fertilize,thereby effectively preventing pregnancy.

(N/A) $1$. Sexually Transmitted Diseases (STDs) are infections that are primarily spread through sexual contact with an infected person.
$2$. These diseases can be caused by various pathogens,including bacteria (e.g.,syphilis,gonorrhea),viruses (e.g.,$HIV$,genital herpes),or parasites.
$3$. Prevention methods include:
- Practicing safe sex by using mechanical barriers like condoms,which significantly reduce the risk of transmission.
- Maintaining personal hygiene and avoiding sexual contact with multiple or unknown partners.
- Seeking early medical diagnosis and treatment if symptoms appear to prevent further spread.

(N/A) $(i)$ Sexually Transmitted Diseases $(STDs)$ are infections that are primarily transmitted from one person to another through sexual contact.
$(ii)$ $AIDS$ (Acquired Immuno Deficiency Syndrome) is an $STD$ caused by the $HIV$ virus,which specifically targets and damages the immune system of the human body.

(B) Copper-$T$ is an intrauterine device $(IUD)$ used for contraception.
Its primary function is to prevent pregnancy by inhibiting the implantation of the fertilized egg in the uterus.
It also releases copper ions which are toxic to sperm,thereby reducing their motility and preventing fertilization.
The common side effect of using Copper-$T$ is uterine irritation or discomfort,which may lead to increased bleeding or cramping in some women.

(D) $(i)$ To prevent unwanted pregnancies.
$(ii)$ To prevent sexually transmitted diseases (STDs).
$(iii)$ To maintain a healthy spacing between children.
$(iv)$ To ensure overall reproductive health and well-being.

(A) The contraceptive method that prevents $STDs$ (Sexually Transmitted Diseases) is the $(a)$ Barrier method.
This method is effective because it creates a physical barrier between the genital organs of the male and the female.
By preventing direct contact between the genital fluids and tissues,it effectively blocks the transmission of pathogens that cause $STDs$.

(N/A) $(i)$ To prevent the illegal abortion of female foetuses.
$(ii)$ To curb the practice of female foeticide,which has significantly disturbed the male-female sex ratio in society.

(C) Surgical methods are used to create blocks in the reproductive pathways to prevent the meeting of gametes.
In males, a surgical procedure called vasectomy involves blocking the $vas deferens$, which prevents the transfer of sperm.
In females, a surgical procedure called tubectomy involves blocking the $fallopian tubes$, which prevents the egg from reaching the uterus and meeting the sperm.

(N/A) Significance of reproductive health in a society:
$1$. It helps in preventing the spread of Sexually Transmitted Diseases $(STDs)$.
$2$. It promotes the advantages of having a small family,which leads to better resource allocation.
$3$. It contributes to a reduction in infant mortality rates.
$4$. It helps in reducing maternal mortality rates through better healthcare and awareness.
Two areas related to reproductive health that have improved in our country over the past $50$ years are:
$1$. Increased awareness and implementation of family planning programs.
$2$. Significant decrease in the incidence and spread of $STDs$ due to better medical facilities and education.

(N/A) Four categories of contraceptive methods are as follows:
$1.$ Barrier methods (e.g.,Condoms,Diaphragms).
$2.$ Chemical methods (e.g.,Oral pills,Spermicides).
$3.$ Intrauterine devices (e.g.,$IUCD$,Copper-$T$).
$4.$ Surgical methods (e.g.,Vasectomy in males,Tubectomy in females).
Two advantages of adopting these methods:
$1.$ Population control: They help in regulating the birth rate and managing population growth.
$2.$ Health and safety: They help in maintaining the reproductive health of women and prevent the transmission of Sexually Transmitted Diseases $(STDs)$ such as $AIDS$ and Syphilis.

(A) Sexually Transmitted Diseases $(STDs)$ are infections that are primarily spread through sexual contact.
$Syphilis$, $HIV-AIDS$, and $Gonorrhoea$ are well-known examples of $STDs$.
$Hepatitis$ (specifically $Hepatitis$ $A$) is primarily transmitted through the fecal-oral route (contaminated food or water), not through sexual contact.
Therefore, $Hepatitis$ is the correct answer.

(B) condom is a barrier method of contraception that is used by males to prevent pregnancy and the transmission of sexually transmitted infections $(STIs)$.
It acts as a physical barrier that prevents the sperm from reaching the female reproductive tract.
Other options like Loop,Copper-$T$,and Mala-$D$ are methods primarily used by females.

(A) The surgical procedure performed in females to prevent pregnancy by blocking the fallopian tubes is known as $Tubectomy$.
In this procedure,the fallopian tubes are either cut or tied,which prevents the egg from reaching the uterus and thus prevents fertilization.
$Vasectomy$ is the corresponding surgical procedure performed in males.
Therefore,the correct option is $A$.

(C) The bacterium $Treponema$ $pallidum$ is the causative agent of the sexually transmitted disease known as Syphilis.
$AIDS$ is caused by the $Human$ $Immunodeficiency$ $Virus$ $(HIV)$.
$Gonorrhea$ is caused by the bacterium $Neisseria$ $gonorrhoeae$.
$Hepatitis$ is a viral infection primarily affecting the liver.

(B) $Neisseria$ $gonorrhoeae$ is a Gram-negative diplococcus bacterium.
It is the causative agent of the sexually transmitted infection known as Gonorrhoea.
$AIDS$ is caused by the Human Immunodeficiency Virus $(HIV)$.
Syphilis is caused by the bacterium $Treponema$ $pallidum$.
Hepatitis is a viral infection affecting the liver (e.g.,Hepatitis $B$ virus).

(A) Syphilis is a sexually transmitted infection $(STI)$ caused by the bacterium $Treponema$ $pallidum$.
$Treponema$ $pallidum$ is a spirochete bacterium that enters the body through mucous membranes or skin abrasions.
Option $A$ is the correct answer.
$B$ causes gonorrhea, $C$ causes typhoid fever, and $D$ causes cholera.

(A) The disease $AIDS$ (Acquired Immuno Deficiency Syndrome) is caused by the Human Immunodeficiency Virus $(HIV)$.
Gonorrhea and Syphilis are bacterial infections caused by $Neisseria$ $\text{gonorrhoeae}$ and $Treponema$ $\text{pallidum}$ respectively.
Infertility is a condition, not a specific infectious disease caused by a pathogen.
Therefore, the correct option is $A$.

(D) The $NACO$ (National $AIDS$ Control Organization) is the division of the Ministry of Health and Family Welfare in India that provides leadership to the national $AIDS$ control programme. It is responsible for creating awareness about $AIDS$ and providing information related to reproductive health and sexually transmitted diseases.

(C) The correct matches are as follows:
$1$. Condom is a mechanical barrier used by males to prevent pregnancy $(1-c)$.
$2$. Copper-$T$ is an intrauterine device $(IUD)$ used by females to prevent pregnancy $(2-a)$.
$3$. Tubectomy is a surgical method of sterilization in females to prevent pregnancy $(3-d)$.
$4$. Sonography is a technique used for prenatal sex determination, which is legally prohibited in many countries $(4-b)$.
Therefore, the correct sequence is $1-c, 2-a, 3-d, 4-b$.
