Infertility Questions in English

(D) $Mycoplasma$ species are known to be associated with various urogenital tract infections in humans.
$M. hominis$,$M. fermentans$,and $T. mycoplasma$ (also known as $Ureaplasma$ $urealyticum$) have all been implicated in reproductive health issues,including infertility and sterility in humans.
Therefore,all three species mentioned are associated with this condition.

(D) $Mycoplasma \ hominis$ is a species of bacteria belonging to the class $Mollicutes$. It is a commensal organism of the human urogenital tract. It is known to be associated with various clinical conditions,including pelvic inflammatory disease,bacterial vaginosis,and it has been linked to reproductive issues such as infertility in both males and females.

(D) Vitamin $E$ is essential for the normal functioning of reproductive organs,which is why it is often referred to as the fertility vitamin.
Deficiency of vitamin $E$ can lead to sterility (infertility) and muscular atrophy.

(A) In the process of producing a test-tube baby,which is a form of $In$ $Vitro$ $Fertilization$ $(IVF)$,the fertilization of the egg by the sperm occurs outside the female's body in a laboratory setting (in a petri dish or test tube).
Once fertilization occurs and the zygote reaches the $8$-celled or $16$-celled stage,it is transferred into the uterus of the female for further development.
The fetus does not grow in a test tube; it grows inside the mother's uterus.

(B) Sperms are stored in sperm banks using a technique called cryopreservation. In this process, sperms are stored at extremely low temperatures (usually in liquid nitrogen at $-196^{\circ}C$). This extraordinary cold condition slows down the metabolic activities of the sperm cells, allowing them to remain viable and alive for a very long period, which is essential for successful artificial insemination.

(C) Amniocentesis is a medical procedure used primarily in prenatal diagnosis of chromosomal abnormalities and fetal infections,in which a small amount of amniotic fluid is sampled from the amniotic sac surrounding a developing fetus.
Once the amniotic fluid is extracted using a surgical needle,the fetal cells present in the fluid are separated from the liquid portion using the process of centrifugation.
Centrifugation uses centrifugal force to separate particles based on their size,shape,and density,allowing the fetal cells to form a pellet at the bottom of the tube for further genetic analysis.

(B) The process described involves the collection of ova through hormone induction (superovulation),followed by fertilization via artificial insemination. The resulting embryo is then stored at low temperatures (cryopreservation) for future use. This entire procedure is referred to as embryo transplantation or embryo transfer technology.

(B) $GIFT$ stands for $\text{Gamete intra-fallopian transfer}$.
In this assisted reproductive technology,the gametes (ova) are collected from a donor and transferred into the fallopian tube of another female who cannot produce an ovum but can provide a suitable environment for fertilization and further development.

(A) The process of producing a test tube baby involves In Vitro Fertilization $(IVF)$.
$1$. The egg is removed from the female's body and fertilized with the husband's sperm in a laboratory setting (in vitro).
$2$. The resulting zygote or early embryo is then transferred back into the female's uterus for further development.
$3$. This technique is commonly referred to as Zygote Intra-Fallopian Transfer $(ZIFT)$ or Intra-Uterine Transfer $(IUT)$ depending on the stage of the embryo transferred.

(D) In cases where the male partner is unable to inseminate the female due to a very low sperm count,the technique of Artificial Insemination $(AI)$ is used.
In this technique,the semen collected either from the husband or a healthy donor is artificially introduced into the vagina or into the uterus (Intrauterine Insemination - $IUI$) of the female.

(A) In assisted reproductive technologies,embryos are transferred based on their developmental stage.
If the embryo has reached a stage with more than $16$ blastomeres,it is referred to as a morula or blastocyst stage.
According to the $IUT$ (Intra-Uterine Transfer) technique,embryos with more than $8$ blastomeres are transferred directly into the uterus to complete their further development.
Therefore,the correct option is $A$.

(D) $GIFT$ stands for Gamete Intra Fallopian Transfer.
This is an assisted reproductive technology used for females who cannot produce an ovum but can provide a suitable environment for fertilisation and further development.
In this technique,gametes (sperm and ovum) are collected from donors and transferred into the Fallopian tube of the female recipient.
Fertilisation occurs naturally inside the female body (in vivo fertilization).

(A) : In the artificial insemination technique,the semen of a healthy donor male is collected and introduced artificially through a flexible polyethylene catheter into the vagina or into the uterus,which is called Intra-Uterine Insemination $(IUI)$.
Best results are obtained when the motile sperm count is more than $10$ million.
The fertilizing capacity of spermatozoa (sperms) lasts for $24-48$ hours.
The procedure may be repeated $2-3$ times over a period of $2-3$ days.

(C) The correct answer is $C$.
In the technique of $IVF$ (In Vitro Fertilization),the zygote or early embryo is transferred into the female reproductive tract.
According to the $GIFT$ and $IUT$ protocols,embryos with up to $8$ blastomeres are transferred into the fallopian tube ($ZIFT$ - Zygote Intra Fallopian Transfer),while embryos with more than $8$ blastomeres (morula stage) are transferred into the uterus ($IUT$ - Intra Uterine Transfer) for further development.

(A) $(GIFT)$ stands for Gamete Intra Fallopian Transfer.
This technique involves the transfer of an ovum collected from a donor into the Fallopian tube of another female.
It is specifically recommended for females who cannot produce their own ova but are capable of providing a suitable environment for fertilization and the subsequent development of the embryo.

(B) The correct answer is $(b)$. Assisted reproductive technologies $(ART)$ include a number of special techniques that assist infertile couples to have children.
An important technique of $ART$ is the test-tube baby programme.
The baby produced by conceiving in a culture dish and nursing in the uterus is called a test-tube baby.
This method involves in vitro fertilization $(IVF)$,i.e.,fertilization of male and female gametes outside the body in conditions similar to those in the body,followed by embryo transfer $(ET)$.
Zygote or early embryo up to $8$ blastomeres is transferred into the Fallopian tube,a process known as Zygote Intra Fallopian Transfer $(ZIFT)$.
Embryos with more than $8$ blastomeres are transferred to the uterus to complete their further development.

(D) Adoption is a legal and socially accepted method for childless couples to have children. It is considered a cost-effective and ethical alternative compared to expensive Assisted Reproductive Technologies $(ART)$ like $GIFT$,$ZIFT$,or $IUI$,which involve complex medical procedures and high costs.

(B) $GIFT$ stands for Gamete Intrafallopian Transfer.
It is an Assisted Reproductive Technology $(ART)$ used for women who cannot produce an ovum but can provide a suitable environment for fertilization and further development.
In this procedure,gametes (ova) collected from a donor are transferred into the fallopian tube of another female who cannot produce one.

(A) $ZIFT$ stands for Zygote Intra Fallopian Transfer.
In this technique,a zygote or an early embryo (up to $8$ blastomeres) is collected from a donor or formed in vitro and is transferred into the fallopian tube of the female.
This allows the embryo to undergo natural development and implantation in the uterus.
Therefore,the correct option is $A$.

(B) $GIFT$ stands for Gamete Intra Fallopian Transfer. In this technique,gametes (ova) are collected from a donor and transferred into the fallopian tube of another female who cannot produce an ovum but can provide a suitable environment for fertilization and further development. It does not involve the transfer of embryos. Therefore,the statement in option $B$ is incorrect.

(A) $ICSI$ stands for Intra Cytoplasmic Sperm Injection.
In this specialized procedure,a single sperm is directly injected into the ovum in the laboratory to form an embryo in vitro.
This technique is used when there are male infertility problems,such as low sperm count or poor sperm motility.

(B) $ZIFT$ stands for Zygote Intra Fallopian Transfer.
It is an Assisted Reproductive Technology $(ART)$ used in cases of infertility.
In this procedure,a zygote or an early embryo (with up to $8$ blastomeres) is transferred into the fallopian tube of the female.

(D) The correct answer is Adoption.
Adoption is a legal process that allows individuals or couples to become the legal parents of a child who was not born to them biologically.
It is recognized by law as a valid and ethical method for couples who are unable to conceive or who wish to provide a home to a child in need of parenthood.
Other options like $IUI$ (Intrauterine Insemination),$GIFT$ (Gamete Intrafallopian Transfer),and $ZIFT$ (Zygote Intrafallopian Transfer) are Assisted Reproductive Technologies $(ART)$ used for treating infertility,but they are medical procedures,not legal processes for parenthood in the same sense as adoption.

(C) Amniocentesis is a prenatal diagnostic technique based on the chromosomal pattern in the amniotic fluid surrounding the developing fetus.
It is commonly referred to as the amniotic fluid test.
It is used to determine the sex of the fetus and to detect chromosomal abnormalities such as Down syndrome,hemophilia,and sickle-cell anemia.

(A) In cases where infertility is caused by the male partner's inability to inseminate the female or due to very low sperm counts in the ejaculate,the technique of Artificial Insemination $(AI)$ is used.
In this technique,the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus ($IUI$ - Intra-Uterine Insemination) of the female.

(A) test-tube baby is produced through the process of In-Vitro Fertilization $(IVF)$.
In this procedure,the ovum from the female and sperm from the male are collected and induced to form a zygote under simulated conditions in the laboratory.
The zygote or early embryo (up to $8$ blastomeres) is then transferred into the fallopian tube ($ZIFT$ - Zygote Intra Fallopian Transfer) or into the uterus ($IUT$ - Intra Uterine Transfer) for further development.
Therefore,the baby is not born in a test tube,but the initial fertilization occurs outside the body.

(B) In vitro fertilization $(IVF)$ is an assisted reproductive technology. In this process,the zygote or early embryos up to the $8$-celled stage are transferred into the fallopian tube,a procedure known as Zygote Intra-Fallopian Transfer $(ZIFT)$. Embryos with more than $8$ cells are transferred into the uterus,a procedure known as Intra-Uterine Transfer $(IUT)$.

(D) The test-tube baby program involves the process of In Vitro Fertilization $(IVF)$,where fertilization occurs outside the body in a laboratory setting.
After fertilization,the resulting zygote or early embryo (up to $8$ blastomeres) is transferred into the fallopian tube,a technique known as Zygote Intrafallopian Transfer $(ZIFT)$.
If the embryo has more than $8$ blastomeres,it is transferred into the uterus,known as Intrauterine Transfer $(IUT)$.
Among the given options,$ZIFT$ is the specific technique associated with the test-tube baby program for transferring the zygote into the fallopian tube.

(C) Artificial Insemination $(AI)$ is a technique used in cases where the male partner is unable to inseminate the female or has a very low sperm count. In this procedure,the semen collected either from the husband or a healthy donor is artificially introduced into the vagina or into the uterus ($IUI$ - Intrauterine Insemination) of the female. This helps in overcoming infertility issues related to sperm delivery.

(B) $GIFT$ stands for $Gamete$ $Intra$ $Fallopian$ $Transfer$.
This is an assisted reproductive technology used for women who cannot produce an ovum but can provide a suitable environment for fertilization and further development.
In this procedure,gametes (ova) collected from a donor are transferred into the fallopian tube of another female who cannot produce one.

(A) In assisted reproductive technologies $(ART)$,when the embryo reaches a stage of more than $16$ blastomeres,it is referred to as an intrauterine embryo transfer $(IUT)$.
This procedure involves transferring the embryo directly into the uterus to allow for further development and implantation.
Embryos with $8$ or fewer blastomeres are typically transferred into the Fallopian tube ($ZIFT$ - Zygote Intrafallopian Transfer).
Therefore,the correct site for an embryo with more than $16$ blastomeres is the uterus.

(C) When the male partner has a very low sperm count (oligospermia) or is unable to inseminate the female,Artificial Insemination $(AI)$ is the most suitable technique.
In this method,the semen collected either from the husband or a healthy donor is artificially introduced into the vagina or into the uterus ($IUI$ - Intrauterine Insemination) of the female.
$ICSI$ is used for fertilization in the laboratory when sperm count is extremely low or motility is poor,but $AI$ is the standard clinical approach for low sperm count cases where the female reproductive tract is otherwise functional.

(C) $GIFT$ stands for Gamete Intra Fallopian Transfer.
It is an assisted reproductive technology used for women who cannot produce ova but can provide a suitable environment for fertilization and further development.
In this procedure,an ovum is collected from a donor and transferred into the fallopian tube of the recipient female.
Fertilization and subsequent embryo development occur naturally within the fallopian tube of the recipient.

(D) $ICSI$ (Intracytoplasmic sperm injection) - Formation of embryo by directly injecting sperm into the ovum $(III)$.
$IUI$ (Intrauterine insemination) - Artificial introduction of semen into the vagina or uterus $(I)$.
$IUT$ (Intrauterine transfer) - Transfer of embryo with more than $8$ blastomeres into the uterus $(V)$.
$GIFT$ (Gamete intrafallopian transfer) - Transfer of ovum collected from a donor into the fallopian tube where fertilization occurs $(II)$.
$ZIFT$ (Zygote intrafallopian transfer) - Transfer of the zygote or early embryo (with up to $8$ blastomeres) into a fallopian tube $(IV)$.
Therefore, the correct match is $A-III, B-I, C-V, D-II, E-IV$.

(N/A) Infertility is the inability of a couple to produce a baby even after unprotected intercourse. It might be due to abnormalities present in either male or female,or both partners. The techniques used to assist infertile couples to have children are as follows:
$1$. In-vitro fertilization $(IVF)$: This involves fertilization outside the body of a female. The zygote or early embryo (up to $8$ blastomeres) is transferred into the fallopian tube $(ZIFT)$,and embryos with more than $8$ blastomeres are transferred into the uterus $(IUT)$.
$2$. Gamete Intra-fallopian Transfer $(GIFT)$: This involves the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce one but can provide suitable conditions for fertilization and development.
$3$. Intra-cytoplasmic Sperm Injection $(ICSI)$: This is a specialized procedure in which a sperm is directly injected into the ovum in the laboratory to form an embryo.
$4$. Artificial Insemination $(AI)$: This method involves the collection of semen from the husband or a healthy donor and its artificial introduction into the vagina or uterus of the female. This is used when the male partner is unable to inseminate the female or has a very low sperm count.

(N/A) Infertility is a condition where couples are unable to produce children in spite of unprotected sexual cohabitation.
- Causes: Infertility can be caused by various factors,including physical,congenital,genetic,immunological,or psychological disorders.
- Social Perspective: In India,the female is often blamed for being childless,but in many cases,the problem lies with the male partner.
- Medical Intervention: Specialized health care units,such as infertility clinics,can help in the diagnosis and corrective treatment of these disorders,enabling couples to have children through assisted reproductive technologies $(ART)$.

(N/A) Assisted Reproductive Technologies $(ART)$ are specialized medical techniques used to help infertile couples conceive and have children.
Importance: These technologies provide hope to couples who are unable to conceive naturally due to various medical reasons,such as blocked fallopian tubes,low sperm count,or ovulation disorders.
Methods under $ART$:
$(i)$ $IVF$ (In Vitro Fertilization): Fertilization occurs outside the body in laboratory conditions. The zygote or early embryos (up to $8$ blastomeres) are transferred into the fallopian tube,known as $ZIFT$ (Zygote Intra Fallopian Transfer). Embryos with more than $8$ blastomeres are transferred into the uterus,known as $IUT$ (Intra Uterine Transfer).
$(ii)$ $GIFT$ (Gamete Intra Fallopian Transfer): An ovum collected from a donor is transferred into the fallopian tube of another female who cannot produce an ovum but can provide a suitable environment for fertilization and development.
$(iii)$ $ICSI$ (Intra Cytoplasmic Sperm Injection): $A$ specialized procedure where a single sperm is directly injected into the ovum to form an embryo in the laboratory.
$(iv)$ $AI$ (Artificial Insemination): Semen collected from the husband or a healthy donor is artificially introduced into the vagina or uterus ($IUI$ - Intra Uterine Insemination) of the female to treat cases of male infertility.

(N/A) Couples who are unable to conceive naturally due to issues such as deficient reproductive organs or an inability to produce viable gametes can have a child through various Assisted Reproductive Technologies $(ART)$.
Commonly used scientific methods include In Vitro Fertilization $(IVF)$,Gamete Intrafallopian Transfer $(GIFT)$,and Zygote Intrafallopian Transfer $(ZIFT)$.
Additionally,surrogacy is another modern method through which parenthood can be achieved.

$(5)$ $\text{Human Immuno deficiency Virus}$
$(6)$ $\text{Sexually Transmitted Infections}$

(B) The primary aim of the "Assisted Reproductive Technology" $(ART)$ programme is to assist childless couples in having children.
These programmes utilize specialized medical techniques such as $ZIFT$ (Zygote Intrafallopian Transfer), $GIFT$ (Gamete Intrafallopian Transfer), $ICSI$ (Intracytoplasmic Sperm Injection), and $AI$ (Artificial Insemination) in cases where natural conception is not possible due to various physiological or anatomical barriers.

(N/A) The $GIFT$ (Gamete Intrafallopian Transfer) procedure specifically involves the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce one,but can provide a suitable environment for fertilization and further development.
Gametes cannot be transferred to the uterus to achieve the same result because the uterine environment is not conducive to fertilization.
If gametes are directly transferred into the uterus,they are likely to be destroyed by phagocytic cells present in the uterine cavity.
Furthermore,the fallopian tube provides the specific physiological conditions required for the fusion of male and female gametes,which the uterus lacks.

(N/A) $IVF$ (In vitro fertilisation) is a process where fertilisation occurs outside the body in conditions similar to those in the body, followed by $ET$ (Embryo Transfer).
In this method, commonly known as the $test-tube-baby$ programme, ova from the wife/donor and sperms from the husband/donor are collected and induced to form a zygote in the laboratory.
The zygote or early embryos (up to $8$ blastomeres) are transferred into the fallopian tube ($ZIFT$ - Zygote Intra Fallopian Transfer), while embryos with more than $8$ blastomeres are transferred into the uterus ($IUT$ - Intra Uterine Transfer) for further development.
These methods are advised for couples suffering from infertility, such as cases where the female has blocked fallopian tubes, low sperm count in the male, or unexplained infertility where natural conception is not possible.

(N/A) Assisted Reproductive Technologies $(ART)$ are specialized medical procedures used to assist infertile couples in having children. Three common techniques are described below:
$1$. $IVF-ET$ ($In$ $vitro$ $fertilisation$ and $Embryo$ $Transfer$): In this method,popularly known as the test-tube baby programme,ova from the wife/donor and sperms from the husband/donor are collected and induced to form a zygote under laboratory conditions. The zygote or early embryos (up to $8$ blastomeres) are transferred into the fallopian tube ($ZIFT$ - $Zygote$ $Intra$ $Fallopian$ $Transfer$),while embryos with more than $8$ blastomeres are transferred into the uterus ($IUT$ - $Intra$ $Uterine$ $Transfer$).
$2$. $GIFT$ ($Gamete$ $Intra$ $Fallopian$ $Transfer$): This technique involves the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce an ovum but can provide a suitable environment for fertilization and further development.
$3$. $ICSI$ ($Intra$ $Cytoplasmic$ $Sperm$ $Injection$): This is a specialized laboratory procedure where a single sperm is directly injected into the ovum to form an embryo.

(A) The correct matches are:
$a-q-y$: $ZIFT$ ($Zygote$ $Intra$ $Fallopian$ $Transfer$) involves the transfer of an embryo with up to $8$ blastomeres into the fallopian tube.
$b-p$: $ART$ ($Assisted$ $Reproductive$ $Technology$) is the umbrella term for these methods.
$c-s-z$: $GIFT$ ($Gamete$ $Intra$ $Fallopian$ $Transfer$) involves the transfer of an ovum collected from a donor into the fallopian tube of another female.
$d-r-x$: $IVF$ ($In$ $Vitro$ $Fertilization$) followed by $ET$ ($Embryo$ $Transfer$) involves transferring an embryo with more than $8$ blastomeres into the uterus.
Therefore,the correct sequence is $a-q-y, b-p, c-s-z, d-r-x$.

(B) The techniques where embryos are transferred into the female reproductive tract are $ZIFT$ (Zygote Intra Fallopian Transfer) and $IUT$ (Intra Uterine Transfer).
In $ZIFT$,the zygote or early embryos (up to $8$ blastomeres) are transferred into the fallopian tube.
In $IUT$,embryos with more than $8$ blastomeres are transferred into the uterus.
$GIFT$ (Gamete Intra Fallopian Transfer) involves the transfer of gametes (ova),not embryos,and $ICSI$ (Intra Cytoplasmic Sperm Injection) is a procedure to form an embryo,not a transfer technique for an already formed embryo.

(A) In Assisted Reproductive Technologies $(ART)$,embryo transfer techniques are used for women who cannot conceive naturally.
$ZIFT$ ($Zygote$ $Intra$ $Fallopian$ $Transfer$) involves the transfer of a zygote or early embryo (up to $8$ blastomeres) into the fallopian tube.
$IUT$ ($Intra$ $Uterine$ $Transfer$) involves the transfer of embryos with more than $8$ blastomeres into the uterus.
$GIFT$ ($Gamete$ $Intra$ $Fallopian$ $Transfer$) is used when the woman can produce ova but cannot provide a suitable environment for fertilization,involving the transfer of gametes rather than embryos.
$ICSI$ ($Intra$ $Cytoplasmic$ $Sperm$ $Injection$) is a procedure to fertilize an ovum in the laboratory.
Therefore,$ZIFT$ and $IUT$ are the primary techniques used for embryo transfer.

(D) $ART$ (Assisted Reproductive Technology) is a group of techniques used to assist couples struggling with infertility to conceive.
$IVF$ (In Vitro Fertilization),$ZIFT$ (Zygote Intra Fallopian Transfer),and $GIFT$ (Gamete Intra Fallopian Transfer) are well-known methods of $ART$.
$AFT$ is not a standard $ART$ method; therefore,it is not included in this category.

(A) The $IVF$ (In Vitro Fertilization) technique is commonly known as the test-tube baby program.
In this process,fertilization occurs outside the body in laboratory conditions,simulating the environment of the female reproductive tract.
The resulting embryo is then transferred into the uterus for further development.
