Answer : 
  • a)
    Protection from STD’s, contraceptive and ARTs
Successful implementation of various action plans to attainreproductive health requires strong infrastructural facilities, professionalexpertise and material support. These are essential to provide medicalassistance and care to people in reproduction-related problems likepregnancy, delivery, STDs, abortions, contraception, menstrual problems,infertility, etc. Implementation of better techniques and new strategiesfrom time to time are also required to provide more efficient care andassistance to people. Statutory ban on amniocentesis (a foetal sexdetermination test based on the chromosomal pattern in the amnioticfluid surrounding the developing embryo) for sex-determination to legallycheck increasing female foeticides, massive child immunisation, etc., aresome programmes that merit mention in this connection.

In ET technique the embryo is transferred into _________.
  • a)
    Always fallopian tube
  • b)
    Always uterus
  • c)
    Fallopian tube or uterus
  • d)
    Ovary
Correct answer is option 'C'. Can you explain this answer?

Nikita Singh answered
In ET (embryo transfer) technique, in vitro fertilized embryo is transferred into the fallopian tube or uterus for further development.
  • In this type of technique, male and female gametes are fused outside the mother's body. It is used either when the male cannot produce enough sperms to fertilize the ovum or the females can not release ova for the purpose.
  • After the embryo reaches 8 celled stages, known as the morula, it is transferred to the female fallopian tubule. If it is in the 16 celled stages, known as blastomere, it is transferred directly to the female uterus
Embryo Transfer technique:
Hence, the correct option is C.

Anjali Iyer answered
Gamete Intrafallopian transfer (GIFT):
It is a technique that involves the transfer of gamete (ovum) from a donor into the fallopian tube of the recipient female who is unable to produce eggs, but has the ability to conceive and can provide right conditions for the development of an embryo.

The technique called gamete intrafallopian transfer (GIFT) is recommended for those females: [2011 M]
  • a)
    Who cannot produce an ovum.
  • b)
    Who cannot retain the foetus inside uterus.
  • c)
    Whose cervical canal is too narrow to allow passage for the sperms.
  • d)
    Who cannot provide a suitable environment for fertilization. 
Correct answer is option 'A'. Can you explain this answer?

Arya Khanna answered
GIFT- Gamete intra fallopian transfer method is used in females who cannot produce ova but can provide suitable envoirnment for fertilization and further development of embryo in the oviducts. In such cases, ovum from the donor female is surgically removed and is then introduced into the fallopian tube of such females. So, the correct answer is 'Who cannot produce an ovum'.
Correct answer is A.

In which of the following techniques, the embryos are transferred to assist those females who cannot conceive?     [NEET 2020]

    ZIFT and IUT
  • d)
    GIFT and ZIFT
Correct answer is option 'C'. Can you explain this answer?

Preeti Iyer answered
When females cannot conceive then embryo transfer is done by using ZIFT and IUT technique. In this method, ova from female & sperms from male is collected and are induced in the laboratory under simulated conditions to form a zygote. The zygote with up to 8 blastomeres is transferred into the fallopian tube through ZIFT or embryos with more than 8 blastomeres are transferred into the uterus through IUT.

Amniocentesis is a method to_________.
  • a)
    Detect genetic disorder
  • b)
    Medical termination of pregnancy
  • c)
    Fertilize the egg
  • d)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Akash Menon answered
Amniocentesis is a prenatal diagnostic procedure that involves the removal of a small amount of amniotic fluid from the sac surrounding the fetus. This procedure is performed during the second trimester of pregnancy, typically between the 15th and 20th week.

Detection of Genetic Disorders:

The main purpose of amniocentesis is to detect genetic disorders in the developing fetus. The amniotic fluid contains cells shed by the fetus, which can be analyzed for chromosomal abnormalities or genetic mutations. This information can help parents and healthcare providers prepare for the birth of a child with a genetic disorder.

Procedure:

During the procedure, a thin needle is inserted through the belly into the amniotic sac, where a small amount of amniotic fluid is collected. The procedure is guided by ultrasound imaging to ensure that the needle is safely inserted and to monitor the fetus during the procedure. The collected fluid is then sent to a laboratory for analysis.

Risks:

Although amniocentesis is generally considered safe, there are some risks involved. These include a small risk of miscarriage or infection, as well as the possibility of injury to the fetus or mother during the procedure. However, the benefits of amniocentesis in detecting genetic disorders often outweigh these risks.

In conclusion, amniocentesis is a valuable tool for detecting genetic disorders during pregnancy, and it can help parents and healthcare providers make informed decisions about the care and treatment of the developing fetus.

Indian population is_________________.
  • a)
    Mature population
  • b)
    Young population
  • c)
    Ageing population
  • d)
    None of these
Correct answer is option 'B'. Can you explain this answer?

Maya Gupta answered
Lactational amenorrhea is a natural form of birth control that occurs when a woman is breastfeeding. It is caused by the hormones that are released during breastfeeding, which suppress ovulation. This means that women who are breastfeeding may not ovulate and therefore may not have a menstrual period for a period of time after giving birth.

Maximum Period after Parturition:

The maximum period after parturition during which lactational amenorrhea can prevent chances of fertilization is six months. After this time, the hormones that suppress ovulation begin to decrease, and the chances of ovulation and subsequent fertilization increase. Therefore, women who rely on lactational amenorrhea as a form of birth control should use another method of contraception after six months postpartum.

Effectiveness:

Lactational amenorrhea can be an effective form of birth control if certain conditions are met. These conditions include:

- The woman is exclusively breastfeeding, meaning that she is not giving the baby any other food or drink besides breast milk.
- The baby is less than six months old.
- The woman has not had a menstrual period since giving birth.

If these conditions are met, lactational amenorrhea can be up to 98% effective in preventing pregnancy. However, if any of these conditions change (for example, if the woman begins to supplement with formula or if the baby becomes older than six months), the effectiveness of lactational amenorrhea may decrease.

Conclusion:

In conclusion, lactational amenorrhea is a natural form of birth control that can be effective for up to six months postpartum. Women who rely on lactational amenorrhea as a form of birth control should be aware of its limitations and should use another form of contraception after the six-month period has ended.

From the sexually transmitted diseases mentioned below, identify the one which does not specifically affect the sex organs:
  • a)
    AIDS
  • b)
    Genital warts
  • c)
    Syphilis
  • d)
    Gonorrhoea
Correct answer is option 'A'. Can you explain this answer?

Rajeev Saxena answered
Syphilis, gonorrhoea and genital warts as STD caused by Treponemapallidum ,Neisseria gonorrhoeae and human papilloma virus. These pathogens directly infectand damage sex organs causing ichting fluid discharge, slight pain and swelling of genitalia. AIDS (Acquired Immuno Deficiency Syndrome) is a set of symptoms caused by HIVvirus in humans. It is transmitted through sexual contacts from infected to healthy person. The HIV virus does not directly affect sex organs as such but produce other set of symptoms in the body of infected person. 

One of the legal methods of birth control is :
[NEET 2013]
  • a)
    abortion by taking an appropriate medicine 
  • b)
    by having coitus at the time of day break
  • c)
    by a premature ejaculation during coitus
  • d)
    by abstaining from coitus from day 10 to 17 of the menstrual cycle
Correct answer is option 'D'. Can you explain this answer?

Shounak Patel answered
Method of Birth Control: Abstaining from Coitus from Day 10 to 17 of the Menstrual Cycle

Explanation:
Abstaining from coitus from day 10 to 17 of the menstrual cycle is a legal method of birth control. This method is also known as the "rhythm method" or "calendar method." The menstrual cycle typically lasts for 28 days, and ovulation occurs around day 14. By abstaining from sexual intercourse during days 10-17, one can avoid the fertile period of the menstrual cycle and prevent pregnancy.

Advantages:
1. This method is free and does not require any special equipment or medication.
2. It is a natural method and does not involve any hormonal changes in the body.
3. It can be used by couples who have religious or moral objections to other forms of birth control.

Disadvantages:
1. This method requires a high degree of discipline and consistency to be effective.
2. It is not suitable for women with irregular menstrual cycles.
3. There is still a small risk of pregnancy, as ovulation can occur earlier or later than expected.

Conclusion:
Abstaining from coitus from day 10 to 17 of the menstrual cycle is a legal and natural method of birth control. However, it requires careful planning and consistency to be effective. Couples should be aware of the advantages and disadvantages before choosing this method of birth control.

  • a)
    POST
  • b)
    ZIFT
  • c)
    IVF 
  • d)
    GIFT
Correct answer is option 'B'. Can you explain this answer?

Akanksha Das answered
ZIFT (Zygote Intrafallopian Transfer) involves the transfer of an embryo at the 8-celled stage into the fallopian tube of a female. This is a type of assisted reproductive technology used to treat infertility.

Process of ZIFT:
The process of ZIFT involves the following steps:

1. Ovarian Stimulation: The female patient is given medication to stimulate the ovaries to produce multiple eggs.

2. Egg Retrieval: The eggs are retrieved from the ovaries using a needle guided by ultrasound.

3. Fertilization: The eggs are fertilized with sperm in a laboratory dish to create embryos.

4. Embryo Transfer: The embryos are transferred into the fallopian tube through a laparoscopic procedure.

5. Pregnancy Test: The patient is monitored for pregnancy through a blood test or ultrasound.

Advantages of ZIFT:
1. Higher Success Rates: ZIFT has higher success rates compared to traditional IVF methods.

2. Natural Implantation: The embryo is transferred into the fallopian tube, which is a natural environment for implantation, increasing the chances of pregnancy.

3. Fewer Multiple Pregnancies: ZIFT reduces the risk of multiple pregnancies compared to other assisted reproductive technologies.

Disadvantages of ZIFT:
1. Invasive Procedure: ZIFT requires a laparoscopic procedure, which is an invasive procedure that carries risks.

2. Limited Availability: ZIFT is not widely available in all fertility clinics.

3. Higher Cost: ZIFT is more expensive than traditional IVF methods.

Conclusion:
ZIFT is a type of assisted reproductive technology that involves transferring an embryo at the 8-celled stage into the fallopian tube of a female. It has higher success rates compared to traditional IVF methods and reduces the risk of multiple pregnancies. However, it is an invasive procedure that is not widely available and is more expensive than traditional IVF methods.

Preventing Transmission of STDs

Sexually transmitted diseases (STDs) are infections that are spread through sexual contact. The following measures can help in preventing the transmission of STDs:

Using Condoms during Intercourse
Using condoms is one of the most effective ways to prevent the transmission of STDs during sexual activity. Condoms act as a barrier and reduce the risk of infection. They should be used consistently and correctly to maximize their effectiveness.

Avoiding Sex with Multiple Partners
Having sex with multiple partners increases the risk of contracting STDs. Limiting sexual partners or being in a mutually monogamous relationship can decrease the risk of transmission.

Visiting a Qualified Doctor if Symptoms are Observed
If an individual experiences symptoms such as genital sores, abnormal discharge, or pain during urination, they should visit a qualified doctor. Early diagnosis and treatment can help prevent the spread of STDs.

Not Sharing Shaving Blades with Friends
Sharing personal items such as shaving blades, towels, or underwear can increase the risk of transmission of STDs. It is important to use personal items and avoid sharing them with others to prevent the spread of infection.

Conclusion
Preventing the transmission of STDs is crucial for maintaining sexual health. Using condoms, limiting sexual partners, seeking medical attention if symptoms are observed, and avoiding sharing personal items can all help decrease the risk of infection.

One of the following is NOT a method of contraception – which one?
[NEET Kar. 2013]

    Tubectomy
  • b)
    Condoms
  • c)
    Pills of a combination of oxytocin and vasopressin
  • d)
    Lippes loop
Correct answer is option 'C'. Can you explain this answer?

Ashwini Khanna answered
Oxytocin is birth hormone and acts on the smooth muscles of our body and stimulates their contraction. Vasopressin acts mainly at the kidney and stimulates resorption of water and electrolytes and reduces loss of water through urine. Hence, it is also called as anti-diuretic hormone (ADH).

Cu ions released from copper - releasing Intra Uterine Devices (IUDs): [2010]

Intra-uterine devices are inserted by doctors in the uterus through vagina. They are available as the non-medicated IUDs, copper releasing IUDs and hormonereleasing IUDs.

Which period of menstrual cycle is called risky period of conception?
  • a)
    7th to 13th day
  • b)
    17th to 25th day
  • c)
    3rd to 7th day
  • d)
    10th to 17th day
Correct answer is option 'D'. Can you explain this answer?

The risky period of conception in the menstrual cycle is the ovulation period, which occurs around the 14th day of a 28-day menstrual cycle.

Explanation:
- Menstrual cycle is the regular natural change that occurs in the female reproductive system that makes pregnancy possible.
- The menstrual cycle is typically 28 days long, but can vary from 21 to 35 days.
- The cycle is divided into three phases: the follicular phase (days 1-14), ovulation (day 14), and the luteal phase (days 15-28).
- Ovulation is the process where an egg is released from the ovary and travels down the fallopian tube, where it can be fertilized by sperm.
- Ovulation typically occurs around day 14 of a 28-day menstrual cycle.
- The period around ovulation is considered the risky period of conception, as it is the time when the egg is available to be fertilized by sperm.
- Sperm can survive in the female reproductive tract for up to five days, so the fertile window for conception is actually the five days leading up to ovulation, as well as ovulation day itself.
- Therefore, the risky period of conception is considered to be from the 10th to the 17th day of the menstrual cycle (assuming a 28-day cycle).

Induced abortion is also called
  • a)
    MTP
  • b)
    PID
  • c)
    SID
  • d)
    IUD
Correct answer is option 'A'. Can you explain this answer?

Rajat Kapoor answered
MTP is Medical Termination of Pregnancy. It also called induced abortion. It is the medical way of getting rid of unwanted pregnancy. Any qualified gynecologist (MD/DGO) can perform MTP. Any MBBS Doctor, who has obtained training in MTP, is allowed to perform this procedure. However, MTP should always be performed at a place recognized by government authorities.

The test-tube Baby Programme employs which one of the following techniques
[2012]
  • a)
    Intra cytoplasmic sperm injection (ICSI)
  • b)
    Intra uterine insemination (IUI)
  • c)
    Gamete intra fallopian transfer (GIFT)
  • d)
    Zygote intra fallopian transfer (ZIFT)
Correct answer is option 'D'. Can you explain this answer?

Test-tube Baby Programme and Zygote Intra Fallopian Transfer (ZIFT)

The Test-tube Baby Programme is a fertility treatment that involves combining sperm and eggs outside the body in a laboratory dish, and then transferring the resulting embryo into the woman's uterus. Zygote Intra Fallopian Transfer (ZIFT) is one of the techniques used in the Test-tube Baby Programme.

Zygote Intra Fallopian Transfer (ZIFT)

Zygote Intra Fallopian Transfer (ZIFT) is a fertility treatment that involves the following steps:

1. Egg Retrieval: The woman undergoes ovarian stimulation to produce multiple eggs. The eggs are then retrieved from the ovaries using a transvaginal ultrasound-guided needle.

2. Fertilization: The retrieved eggs are combined with sperm in a laboratory dish.

3. Zygote Formation: The fertilized eggs develop into zygotes (fertilized eggs).

4. Zygote Transfer: The zygotes are transferred into the woman's fallopian tubes using a laparoscope.

5. Implantation: The zygotes implant in the woman's uterus and develop into embryos.

Comparison with other techniques

Intra cytoplasmic sperm injection (ICSI), Intra uterine insemination (IUI), and Gamete intra fallopian transfer (GIFT) are other techniques used in the Test-tube Baby Programme. However, Zygote Intra Fallopian Transfer (ZIFT) is different from these techniques in the following ways:

- Intra cytoplasmic sperm injection (ICSI) involves injecting a single sperm directly into an egg. This technique is used when the man has a low sperm count or poor sperm motility. ZIFT, on the other hand, involves the transfer of fertilized eggs (zygotes) into the fallopian tubes.

- Intra uterine insemination (IUI) involves placing sperm inside the woman's uterus to increase the chances of fertilization. This technique is used when the man has a low sperm count or poor sperm motility. ZIFT, on the other hand, involves the transfer of fertilized eggs (zygotes) into the fallopian tubes.

- Gamete intra fallopian transfer (GIFT) involves placing eggs and sperm into the woman's fallopian tubes to allow fertilization to occur naturally. This technique is used when the man's sperm count and motility are normal, and the woman's fallopian tubes are healthy. ZIFT, on the other hand, involves the transfer of fertilized eggs (zygotes) into the fallopian tubes.

Conclusion

Zygote Intra Fallopian Transfer (ZIFT) is a technique used in the Test-tube Baby Programme that involves the transfer of fertilized eggs (zygotes) into the woman's fallopian tubes. ZIFT is different from other techniques like Intra cytoplasmic sperm injection (ICSI), Intra uterine insemination (IUI), and Gamete intra fallopian transfer (GIFT).

A test-tube baby means a baby born when
  • a)
    It is developed by tissue culture method.
  • b)
    The ovum is fertilised externally and thereafter implanted in the uterus.
  • c)
    It is developed in a test tube
  • d)
    It develops from a non-fertilised egg.
Correct answer is option 'B'. Can you explain this answer?

Jyoti Kapoor answered
Test tube bay production involves two main steps - in vitro fertilization (IVF) and embryo transfer (ET). Historically the first attempt to produce the test tube baby was by an Italian scientise Petrucci (1959). In his experiment he removed an ovum from a patient and put it in the middle of spermatozoa in a glass dome. One of the sperms fertilized the egg and a small embryo formed, but this survived only for 29 days.

However Petrucci's experiment opened up a new horizon and a new hope for infertile parents. In recent years two British scientists Edwards and Steptoe have done pioneering work in the field of test tube babies. The first scientifically recorded test tube baby in the world was born on July 25 1978 and the baby girl was named Louise Joy Brown.

In our country the first recorded instane of a test tube baby was under the supervision of Dr. Indira Hinduja in KEM Hospital Bombay in 1986. Subsequently test tube babies have been reported by Dr. Baidyanath Chakravarthi of Calcutta.

Which of the following contraceptive methods involve the role of hormone?      [NEET 2019]
  • a)
    Pill, Emergency contraception, Barrier methods
  • b)
    Lactational amenorrhea, Pills, Emergency contraceptives
  • c)
    Barrier method, Lactational amenorrhea pills
  • d)
    Cut, Pills, Emergency contraceptive
Correct answer is option 'B'. Can you explain this answer?

Suresh Iyer answered
  • Lactational amenorrhea method is based on the fact that ovulation and therefore the menstrual cycle does not occur during the period of intense lactation following parturition. This is because breastfeeding disrupts the pulsatile release of GnRH from the hypothalamus and reduces gonadotropin-releasing hormones.
  • Pills are hormonal preparations (either progesterone or progestogen- estrogen combinations) in the form of tablets which are administered orally by females. They inhibit ovulation, implantation as well as alter the quality of cervical mucus. 
  • Emergency contraceptives are pills that contain levonorgestrel, a type of progestin that helps to prevent pregnancy when taken in few days after sex.

Absence of menstruation during period of intense lactation following parturition is called as?
  • a)
    Coitus interruption
  • b)
    Mellitus
  • c)
    Lactational amenorrhea
  • d)
    Lactationalgonorrhea
Correct answer is option 'C'. Can you explain this answer?

Nilotpal Gupta answered
During intense lactation just after the delivery the menstrual cycle get stopped and there is no chance of pregnancy. This absence of menstruation is called lactational amenorrhea.

Importance of Sex Education in Schools

Sex education is a critical aspect of education that should be delivered in schools to help students understand human sexuality and sexual behavior. The correct reason for delivering sex education in schools is to discourage myths and misconceptions. Here are some of the reasons why sex education is necessary in schools:

1. Preventing Unwanted Pregnancies: Sex education helps students understand how to protect themselves from unintended pregnancies. It provides information on different contraceptive methods, their effectiveness, and how to use them correctly.

2. Preventing Sexually Transmitted Infections (STIs): Sex education helps students understand how to protect themselves from STIs. It provides information on how STIs are transmitted, their symptoms, and how to prevent them.

3. Encouraging Healthy Relationships: Sex education helps students understand the importance of healthy relationships. It provides information on how to build healthy relationships, how to communicate effectively, and how to recognize signs of an unhealthy relationship.

4. Reducing Sexual Violence: Sex education helps students understand the importance of consent and how to recognize sexual violence. It provides information on how to report sexual violence and where to seek help.

5. Overcoming Stigma: Sex education helps students overcome stigma and discrimination related to sexuality. It provides information on different sexual orientations and gender identities, and how to respect and accept diversity.

Conclusion

Sex education is an essential aspect of education that helps students make informed decisions about their sexual health and behavior. It provides information on how to protect themselves from unintended pregnancies, STIs, and sexual violence. It also encourages healthy relationships and respect for diversity. Therefore, it is necessary to deliver sex education in schools to discourage myths and misconceptions.

Contraceptive oral pills help in birth control by:
  • a)
    By preventing ovulation
  • b)
    Killing the sperm
  • c)
    Killing the ova
  • d)
    Forming barrier between sperm and ova
Correct answer is option 'A'. Can you explain this answer?

Ankit Patel answered
Oral contraceptive pills are a type of hormonal birth control method that contain synthetic versions of the hormones estrogen and progesterone. These hormones work together to prevent pregnancy in several ways:

Preventing Ovulation
- The primary way that contraceptive pills prevent pregnancy is by preventing ovulation. Ovulation is the process in which an egg is released from the ovary and can be fertilized by sperm. By taking the pill regularly, the hormones in the pill signal to the body that ovulation has already occurred, which prevents the release of an egg. Without an egg, there is no chance of fertilization and pregnancy cannot occur.

Thickening Cervical Mucus
- In addition to preventing ovulation, contraceptive pills also thicken the cervical mucus. The cervix is the opening at the bottom of the uterus that leads to the vagina. Normally, the cervical mucus is thin and watery, which allows sperm to swim through it and reach the egg. However, when a woman is taking contraceptive pills, the hormones in the pill cause the cervical mucus to thicken and become more viscous, making it more difficult for sperm to penetrate and reach the egg.

Altering the Uterine Lining
- Lastly, contraceptive pills can also alter the lining of the uterus. The lining of the uterus is where a fertilized egg implants and grows into a fetus. The hormones in the pill can change the lining of the uterus to make it less hospitable to a fertilized egg, making it less likely that a pregnancy will occur even if an egg is released and fertilized.

By working together in these ways, contraceptive pills are highly effective at preventing pregnancy when taken correctly and consistently.
