A diagnostic test in which amniotic fluid is sampled can reveal chromosomal abnormalities of the foetus. The chapter states that a statutory ban was placed on its routine use. What is the main reason for this ban?

It was being misused for sex determination leading to selective female foeticide

It frequently caused infertility in the mother after the test

It transmitted sexually transmitted infections to the foetus

It could only detect metabolic disorders and not genetic disorders

Two surgical sterilisation methods are compared. In method X a small part of the vas deferens is cut or tied, while in method Y a small part of the fallopian tube is cut or tied. Which statement about these methods is correct?

X is vasectomy done in the male and Y is tubectomy done in the female

Both X and Y block ovulation and are easily reversible

X is tubectomy done in the female and Y is vasectomy done in the male

X is done in the female and Y is done in the male

A gynaecologist helps an infertile couple in whom the female can produce a normal ovum but cannot conceive naturally. In the technique chosen, the ovum collected from a donor/wife is fertilised in the laboratory and the resulting early embryo (up to the 8-blastomere stage) is transferred into the fallopian tube. This technique is:

ZIFT (Zygote Intra Fallopian Transfer)

GIFT (Gamete Intra Fallopian Transfer)

ICSI (Intra Cytoplasmic Sperm Injection)

IUI (Intra Uterine Insemination)

Q1. A diagnostic test in which amniotic fluid is sampled can reveal chromosomal abnormalities of the foetus. The chapter states that a statutory ban was placed on its routine use. What is the main reason for this ban?
एक नैदानिक परीक्षण जिसमें उल्बीय द्रव (amniotic fluid) का नमूना लिया जाता है, भ्रूण की गुणसूत्रीय असामान्यताओं को प्रकट कर सकता है। अध्याय बताता है कि इसके नियमित उपयोग पर एक वैधानिक प्रतिबंध लगाया गया। इस प्रतिबंध का मुख्य कारण क्या है?
- A. It frequently caused infertility in the mother after the test / इससे परीक्षण के बाद प्रायः माता में बाँझपन उत्पन्न हो जाता था
- B. It transmitted sexually transmitted infections to the foetus / इससे भ्रूण में यौन संचारित संक्रमण संचरित हो जाते थे
- C. It could only detect metabolic disorders and not genetic disorders / यह केवल उपापचयी विकारों का पता लगा सकता था, आनुवंशिक विकारों का नहीं
- D. It was being misused for sex determination leading to selective female foeticide / इसका दुरुपयोग लिंग निर्धारण के लिए किया जा रहा था जिससे चयनात्मक कन्या भ्रूण हत्या हो रही थी
Solution
Amniocentesis was being misused to determine the sex of the foetus, leading to female foeticide, so its misuse for sex determination was legally banned.
उल्बवेधन का दुरुपयोग भ्रूण के लिंग निर्धारण के लिए किया जा रहा था, जिससे कन्या भ्रूण हत्या हो रही थी, इसलिए लिंग निर्धारण हेतु इसके दुरुपयोग पर कानूनी प्रतिबंध लगाया गया।
Q2. Two surgical sterilisation methods are compared. In method X a small part of the vas deferens is cut or tied, while in method Y a small part of the fallopian tube is cut or tied. Which statement about these methods is correct?
दो शल्य-चिकित्सकीय बंध्यकरण विधियों की तुलना की जाती है। विधि X में शुक्रवाहक (vas deferens) का एक छोटा भाग काटा या बाँधा जाता है, जबकि विधि Y में अंडवाहिनी (fallopian tube) का एक छोटा भाग काटा या बाँधा जाता है। इन विधियों के बारे में कौन-सा कथन सही है?
- A. Both X and Y block ovulation and are easily reversible / X और Y दोनों अंडोत्सर्ग को अवरुद्ध करते हैं और आसानी से प्रतिवर्ती हैं
- B. X is vasectomy done in the male and Y is tubectomy done in the female / X पुरुष में की जाने वाली शुक्रवाहिका-उच्छेदन (vasectomy) है और Y महिला में की जाने वाली अंडवाहिका-उच्छेदन (tubectomy) है
- C. X is tubectomy done in the female and Y is vasectomy done in the male / X महिला में की जाने वाली अंडवाहिका-उच्छेदन (tubectomy) है और Y पुरुष में की जाने वाली शुक्रवाहिका-उच्छेदन (vasectomy) है
- D. X is done in the female and Y is done in the male / X महिला में की जाती है और Y पुरुष में की जाती है
Solution
Vasectomy (in the male) ties/cuts the vas deferens and tubectomy (in the female) ties/cuts the fallopian tube; both block gamete transport and are highly effective but have poor reversibility.
शुक्रवाहिका-उच्छेदन (vasectomy, पुरुष में) शुक्रवाहक को बाँधता/काटता है और अंडवाहिका-उच्छेदन (tubectomy, महिला में) अंडवाहिनी को बाँधता/काटता है; दोनों युग्मक परिवहन को अवरुद्ध करते हैं और अत्यधिक प्रभावी हैं परंतु इनकी प्रतिवर्तनीयता कम होती है।
Q3. A gynaecologist helps an infertile couple in whom the female can produce a normal ovum but cannot conceive naturally. In the technique chosen, the ovum collected from a donor/wife is fertilised in the laboratory and the resulting early embryo (up to the 8-blastomere stage) is transferred into the fallopian tube. This technique is:
एक स्त्री-रोग विशेषज्ञ एक बाँझ दंपति की सहायता करता है जिसमें महिला एक सामान्य अंडाणु उत्पन्न कर सकती है परंतु प्राकृतिक रूप से गर्भधारण नहीं कर सकती। चुनी गई तकनीक में, दाता/पत्नी से एकत्रित अंडाणु को प्रयोगशाला में निषेचित किया जाता है और परिणामस्वरूप बने प्रारंभिक भ्रूण (8-कोरकखंड अवस्था तक) को अंडवाहिनी में स्थानांतरित किया जाता है। यह तकनीक है:
- A. ZIFT (Zygote Intra Fallopian Transfer) / ZIFT (युग्मनज अंतः अंडवाहिनी स्थानांतरण)
- B. GIFT (Gamete Intra Fallopian Transfer) / GIFT (युग्मक अंतः अंडवाहिनी स्थानांतरण)
- C. ICSI (Intra Cytoplasmic Sperm Injection) / ICSI (अंतः कोशिकाद्रव्यी शुक्राणु अंतःक्षेपण)
- D. IUI (Intra Uterine Insemination) / IUI (अंतः गर्भाशयी वीर्यसेचन)
Solution
Transfer of an embryo with up to 8 blastomeres into the fallopian tube is ZIFT (Zygote Intra Fallopian Transfer); an embryo of more than 8 blastomeres is placed into the uterus (IUT).
8 कोरकखंडों तक वाले भ्रूण को अंडवाहिनी में स्थानांतरित करना ZIFT (युग्मनज अंतः अंडवाहिनी स्थानांतरण) है; 8 से अधिक कोरकखंडों वाले भ्रूण को गर्भाशय में रखा जाता है (IUT)।
