Infertility Questions in English

(B) The technique described is $Artificial Insemination$ $(AI)$.
In this method,semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus $(IUI)$ of the female.
$ET$ stands for $Embryo Transfer$.
$IUT$ stands for $Intra Uterine Transfer$.
$IUI$ is a specific type of $AI$ where semen is introduced into the uterus.
Since the question describes the general process of introducing semen into the vagina or uterus,$AI$ is the most appropriate term.

(B) The correct answer is $AI$ (Artificial Insemination).
In cases where the male partner is unable to inseminate the female or due to very low sperm counts in the ejaculates,the infertility problem is corrected by artificial insemination $(AI)$.
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) The term 'test-tube baby' is a misnomer. In this process,fertilization occurs outside the body (in vitro fertilization),but the embryo is then transferred into the uterus of the mother or a surrogate mother for further development. The embryo does not grow inside a test tube. Therefore,the statement that it grows inside a test tube is incorrect.

(C) The correct method is $GIFT$ (Gamete Intrafallopian Transfer).
$GIFT$ 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.
$ZIFT$ (Zygote Intrafallopian Transfer) is used when the zygote is transferred after in vitro fertilization.
$ICSI$ (Intracytoplasmic Sperm Injection) is a specialized procedure to form an embryo in the laboratory.
$IUI$ (Intrauterine Insemination) is used for cases of male infertility.

(B) The correct matches are as follows:
$P$. $AI$ (Artificial Insemination) matches with $III$.
$Q$. $IUI$ (Intrauterine Insemination) matches with $II$.
$R$. $IUT$ (Intrauterine Transfer) matches with $IV$.
$S$. $ET$ (Embryo Transfer) matches with $I$.
Therefore, the correct sequence is $(P-III), (Q-II), (R-IV), (S-I)$.

(C) Cryopreservation is a technique used for the long-term storage of biological materials like gametes,embryos,and tissues.
In this process,the biological material is stored at extremely low temperatures to halt all metabolic activities.
The standard temperature used for cryopreservation is $-196^{\circ} C$,which is achieved using liquid nitrogen.
Therefore,the correct option is $C$.

(A) The $\text{IVF}$ (In Vitro Fertilization) method has several limitations and drawbacks:
$1.$ It requires highly specialized,expensive instruments and reagents,making it costly $(B)$.
$2.$ The widespread use of $\text{IVF}$ may lead to a decrease in the adoption of orphans,as couples prioritize biological children $(D)$.
$3.$ There is a significant biological risk that the early embryo may not survive after implantation $(F)$.
Options $A, C,$ and $E$ are incorrect because $\text{IVF}$ is available in India,donors do not strictly have to be the husband/wife (e.g.,donor gametes can be used),and it is not inherently fatal to the mother.

(A) $\text{GIFT}$ stands for $\text{Gamete Intrafallopian Transfer}$.
In this assisted reproductive technology,the ovum collected from a donor is transferred into the fallopian tube of another female who cannot produce one,but can provide a suitable environment for fertilization and further development.
Since the gametes are placed directly into the fallopian tube,the fusion of the egg and sperm (fertilization) occurs naturally within the fallopian tube of the recipient female.

(B) In cases where the male partner is impotent or suffers from oligospermia (low sperm count), the most effective assisted reproductive technology is $Intrauterine \text{ } Insemination$ $(IUI)$.
In this procedure, semen collected either from the husband or a healthy donor is artificially introduced into the female's uterus.
$GIFT$ $(Gamete \text{ } Intrafallopian \text{ } Transfer)$ is used when the female cannot produce ova but can provide a suitable environment for fertilization.
$ZIFT$ $(Zygote \text{ } Intrafallopian \text{ } Transfer)$ and Embryo transfer are used when fertilization occurs outside the body $(IVF)$.
Therefore, $IUI$ is the appropriate method for male infertility.

(A) The correct expansions for the given assisted reproductive technologies are as follows:
$1$. $IUI$ stands for Intra Uterine Insemination,not Intra uterine implantation.
$2$. $ICSI$ stands for Intra Cytoplasmic Sperm Injection.
$3$. $IUT$ stands for Intra Uterine Transfer.
$4$. $ZIFT$ stands for Zygote Intra Fallopian Transfer.
Therefore,the pair $IUI \longrightarrow$ Intra uterine implantation is incorrect.

(B) In Assisted Reproductive Technology $(ART)$,specifically Zygote Intra-Fallopian Transfer $(ZIFT)$,the zygote or early embryo up to $8$ blastomeres is transferred into the Fallopian tube.
Embryos with more than $8$ blastomeres are transferred into the uterus for further development,a process known as Intra-Uterine Transfer $(IUT)$.
Therefore,an embryo with $8$ blastomeres is specifically suitable for transfer into the Fallopian tube.

(D) In $G.I.F.T.$ (Gamete Intrafallopian Transfer),the ovum collected from a donor is transferred into the fallopian tube of another female who cannot produce one,but can provide suitable conditions for fertilization and further development.
Since the fertilization occurs naturally within the fallopian tube of the female,it is an in vivo fertilization technique.
In contrast,$Z.I.F.T.$ (Zygote Intrafallopian Transfer),$I.U.T.$ (Intra Uterine Transfer),and $I.C.S.I.$ (Intracytoplasmic Sperm Injection) are techniques where fertilization occurs outside the body (in vitro) in a laboratory setting.

(C) Artificial insemination $(AI)$ is a reproductive technique in which semen collected from a donor is artificially introduced into the female reproductive tract.
Specifically, the sperms are introduced into the $cervix$ or the $uterus$ of the female to facilitate fertilization.
Among the given options, the $cervix$ is the most common site for artificial insemination in humans, as it allows the sperm to travel naturally through the uterus to the fallopian tubes.

(B) The correct matching is as follows:
$a$. $ZIFT$ (Zygote Intra Fallopian Transfer): In this technique,the zygote or early embryos (up to $8$ blastomeres) are transferred into the fallopian tube. This matches with $ii$.
$b$. $GIFT$ (Gamete Intra Fallopian Transfer): In this technique,ova and sperms are collected from a donor and injected directly into the fallopian tube (oviduct) where fertilization occurs. This matches with $iv$.
$c$. $ICSI$ (Intra Cytoplasmic Sperm Injection): In this specialized procedure,a single sperm cell is injected directly into the cytoplasm of an ovum. This matches with $i$.
$d$. $IUI$ (Intra Uterine Insemination): In this technique,sperms collected from the husband or a healthy donor are artificially introduced into the uterus. This matches with $iii$.
Therefore,the correct sequence is $a-ii, b-iv, c-i, d-iii$.

(D) The correct answer is $D$.
In $in \, vitro$ fertilization $(IVF)$, embryos are cultured in the laboratory.
If the embryo has up to $8$ blastomeres, it is transferred into the fallopian tube, a process known as Zygote Intra-Fallopian Transfer $(ZIFT)$.
If the embryo has more than $8$ blastomeres, it is transferred directly into the uterus for further development, a process known as Intra-Uterine Transfer $(IUT)$.

(C) The correct answer is $ICSI$ (Intracytoplasmic Sperm Injection).
In this assisted reproductive technology,a single sperm is directly injected into the cytoplasm of the ovum to facilitate fertilization.
$AI$ (Artificial Insemination) involves introducing semen into the female reproductive tract.
$ZIFT$ (Zygote Intrafallopian Transfer) involves transferring a zygote into the fallopian tube.
$GIFT$ (Gamete Intrafallopian Transfer) involves transferring gametes (ovum and sperm) into the fallopian tube.

(A) $GIFT$ (Gamete Intra Fallopian Transfer) is the technique where an ovum collected from a donor is transferred into the fallopian tube of another female who cannot produce one,but can provide a suitable environment for fertilization and further development. Note: The original question mentioned 'testis',which is biologically incorrect for this procedure; it has been corrected to 'ovum'.

(A) The transfer of an early embryo with up to $8$ blastomeres into the fallopian tube is known as Zygote Intrafallopian Transfer $(ZIFT)$.
$IUT$ (Intrauterine Transfer) involves transferring embryos with more than $8$ blastomeres into the uterus.
$IUI$ (Intrauterine Insemination) involves placing sperm directly into the uterus.
$ICSI$ (Intracytoplasmic Sperm Injection) is a laboratory procedure where a single sperm is injected directly into an egg.

(A) The correct answer is $A$.
In the assisted reproductive technology known as Zygote Intrafallopian Transfer $(ZIFT)$,the zygote or early embryo containing up to $8$ blastomeres is collected from the laboratory and transferred into the fallopian tube of the female.
If the embryo has developed beyond the $8$-blastomere stage (e.g.,$16$ or $32$ blastomeres),it is instead transferred into the uterus,a procedure known as Intrauterine Transfer $(IUT)$.

(B) $ZIFT$ stands for Zygote Intra Fallopian Transfer.
In this assisted reproductive technology,the zygote or early embryos (up to $8$ blastomeres) are transferred into the fallopian tube of the female.

(D) The correct option is $D$.
Assisted Reproductive Technologies $(ART)$ is a collection of medical techniques used to help individuals or couples achieve pregnancy when they are facing infertility issues.
$RCH$ stands for Reproductive and Child Health care.
$MTP$ stands for Medical Termination of Pregnancy.
$RTI$ stands for Reproductive Tract Infections.

(C) The correct answer is $C$.
Intra-cytoplasmic sperm injection $(ICSI)$ is a specialized procedure in which a single sperm is directly injected into the ovum to form an embryo in the laboratory.
This technique is primarily used to treat cases of male infertility.

(B) $GIFT$ ($Gamete$ $Intrafallopian$ $Transfer$) is a technique used for females who cannot produce or release viable ova but possess a healthy environment for fertilization and embryonic development.
In this procedure,ova are collected from a donor female and transferred into the fallopian tube of the recipient.
This allows fertilization to occur naturally within the body ($in$ $vivo$) of the recipient.
Therefore,option $B$ is the correct statement.

(B) The correct option is $B$.
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 either into the vagina or into the uterus ($IUI$ - Intra-Uterine Insemination) of the female.
Since the male partner has a low sperm count,$AI$ is the most suitable strategy to increase the chances of fertilisation.

(A) Assisted Reproductive Technology $(ART)$ refers to a set of medical procedures used to treat infertility.
Common $ART$ techniques include:
$1$. In-vitro fertilisation and embryo transfer $(IVF-ET)$.
$2$. Gamete Intra Fallopian Transfer $(GIFT)$.
$3$. Intra Cytoplasmic Sperm Injection $(ICSI)$.
$4$. Artificial insemination $(AI)$.
$5$. Zygote Intra Fallopian Transfer $(ZIFT)$.
Option $A$ mentions 'Zygote Extra Fallopian Transfer',which is not a recognized medical procedure. The correct term is $ZIFT$ (Zygote Intra Fallopian Transfer). Therefore,'Zygote Extra Fallopian Transfer' is not an $ART$ technique.

(D) $GIFT$ ($Gamete$ $Intra-Fallopian$ $Transfer$) is an assisted reproductive technology where gametes (ovum and sperm) are transferred directly into the fallopian tube of the female. Since the gametes are placed in the fallopian tube,the process of fertilization occurs naturally inside the female body. In contrast,$ICSI$,$IUT$,and $ZIFT$ involve fertilization outside the body ($in$ $vitro$).

(D) $GIFT$ stands for Gamete Intra-Fallopian Transfer.
It is an assisted reproductive technology used for females who cannot produce an ovum but can provide a suitable environment for fertilization and embryonic development.
In this procedure,the ovum is collected from a donor and transferred into the fallopian tube of the recipient.
