Question 5. ………… is the type of infertility when exact reason is not known.

  1. Tubal infertility
  2. Idiopathic infertility
  3. Impotency
  4. Cryptorchidism

Answer:  2. Idiopathic infertility

Unexplained infertility is infertility that is idiopathic in the sense that its causes remain unknown even after infertility check up like semen analysis in man, assessment of ovulation and Fallopian tubes in woman, etc.

Question 6. Which of the following diseases causes male infertility?

  1. Scrotal hernia
  2. Phimosis
  3. Orchitis
  4. All of the above

Answer:  4. All of the above

  • All the listed factors cause male infertility. Scrotal hernia is the abnormal protrusion of part of an organ or tissue through the structures normally containing it.
  • Phimosis is a condition in which tight foreskin cannot be pulled back over the head of the penis. Orchitis is an inflammation of one or both testicles.

Thus, option (4) is correct.

Question 7. Orchitis is caused in males due to

  1. Elongated prepuce
  2. Inflammation of testicles
  3. Swelling of spermatid cord
  4. Inflammation of vas deferens

Answer:  2.  Inflammation of testicles

Orchitis is an inflammatory condition of one or both testicles in males. It is generally caused by a viral or bacterial infection. Most cases of orchitis in children are caused by infection with the mumps virus

Question 8. Tubal infertility in females is caused due to

  1. Absence of ovaries
  2. Absence of Fallopian tube
  3. Ligated Fallopian tubes
  4. Infections in reproductive tract

Answer:  3. Ligated Fallopian tubes

Tubal infertility occurs when the Fallopian tube(s) prevent sperm from reaching the fertilisation site to fertilise an egg or prevents a fertilised embryo from reaching the uterus for pregnancy. So, tubal infertility in females is caused due to ligated Fallopian tube.

Question 9. In the production of test tube babies,

  1. Fertilisation and foetus formation is external
  2. Fertilisation and foetus formation is internal
  3. Fertilisation is internal and foetus formation is external
  4. Fertilisation is external and foetus formation is internal

Answer:  4 . Fertilisation is external and foetus formation is internal

  • In the production of test tube babies, an ovum is taken out from a woman’s Fallopian tube and fertilised with preserved sperm in a test tube.
  • After that zygote is formed that is implanted in the woman’s uterus for further embryonic development. Thus, fertilisation is external and foetus formation is internal in test tube babies.

Question 10. In vitro fertilisation is a technique that involves transfer of which one of the following into the Fallopian tube?

  1. Embryo only up to 8 cell stage
  2. Either zygote or early embryo up to 8 cell stage
  3. Embryo of 32 cell stage
  4. A foetus of eight weeks

Answer:  2. Either zygote or early embryo up to 8 cell stage

Zygote Intra Fallopian Transfer (ZIFT) is an example of In Vitro Fertilisation (IVF). In this, the zygote or early embryos up to 8 blastomeres are transferred into the Fallopian tube. If the embryo has more than 8 blastomeres then, it is transferred into uterus. This process is called as IUT.

Question 11. Which of the following is the correct sequence of events in development of test tube baby?

  1. Removal of unfertilised ovum → In vitro fusion of sperm and ovum → Development of zygote up to 32 cell stage → Embryo transfer into the uterus of mother
  2. Fusion of sperm and ovum in vitro → Removal of unfertilised ovum and transfer in to the uterus of mother → Formation and development of zygote up to 32 cell stage
  3. Embryo transfer into the uterus of mother → Formation and development of zygote up to 32 cell stage → Fusion of sperm and ovum in vitro → Removal of unfertilised ovum
  4. Formation and development of zygote up to 32 cell stage → Fusion of sperm and ovum in vitro → Removal of unfertilised ovum → Embryo transfer into the uterus

Answer:  1. Removal of unfertilised ovum → In vitro fusion of sperm and ovum → Development of zygote up to 32 cell stage → Embryo transfer into the uterus of mother.

Question 27. First case of IVF-ET technique success was reported by

  1. Bayliss and Starling Taylor
  2. Robert Steptoe and Gilbert Brown
  3. Louis Joy Brown and Benting Best
  4. Patrick Steptoe and Robert Edwar

Answer:  4. Patrick Steptoe and Robert Edwar

  • First test tube baby (IVF-ET technique) was Louis Joy Brown. He was born to Lesley and Gilbert Brown on July 1978 in England under the assistance of Dr. Patrick Steptoe and Dr. Robert Edward.
  • Dr. Robert Edward got Nobel Prize in 2010 for developing a technique for the production of test tube baby.

Question 28. The technique called Gamete Intra Fallopian Transfer (GIFT) is recommended for those females

  1. Who cannot produce an ovum
  2. Who cannot retain the foetus inside uterus
  3. Whose cervical canal is too narrow to allow passage for the sperms
  4. Who cannot provide suitable environment for fertilisation

Answer:  1. Who cannot produce an ovum

  • Gamete Intra Fallopian Transfer (GIFT) is recommended for those females who cannot produce an ovum.
  • In this process, the eggs of the donor woman are removed and in a form of mixture with sperm transferred into Fallopian tube of another woman who cannot produce ovum, but can provide suitable environment for fertilisation. Thus in GIFT, site of fertilisation is Fallopian tube, not laboratory.

Question 29. GIFT technique is useful for women,

  1. Whose fimbriae fail to capture ovum
  2. Who have sperm antibodies in their cervical secretion
  3. Who have at least one potent Fallopian tube
  4. All of the above

Answer:  4. All of the above

GIFT is useful for women with atleast one potent Fallopian tube. It can help those where fimbriae does not function efficiently or presence of spermicidal antibodies in cervical secretions.

Thus, option (4) is correct.

Question 30. Which of the following is wrongly matched?

  1. IUT – Semen collected from husband or donor is artificially introduced either into the vagina or into the uterus
  2. GIFT – Transfer of embryos with more than 8 blastomeres into the Fallopian tube
  3. ICSI – Sperm directly injected into the ovum
  4. ZIFT – Transfer of embryos with up to 8 blastomeres into the Fallopian tube
  5. IVF – Fertilisation outside the body in almost similar conditions as that in the body

Answer:  2. GIFT – Transfer of embryos with more than 8 blastomeres into the Fallopian tube

Option (2) is wrongly matched pair and can be corrected as GIFT or Gamete Intra Fallopian Transfer is a method of transfer of an ovum collected from a donor female into the Fallopian tube. Rest options are correctly matched pairs.

Biology MCQ For NEET With Answers

Question 31. The stage of cells at which it is transferred into the uterus after induced fertilisation of ova in the laboratory is

  1. Embryo at 4 blastomeres stage
  2. Embryo at 2 blastomeres stage
  3. Morula
  4. Zygote

Answer:  3. Morula

After induced fertilisation, embryo at morula stage is transferred into the uterus.

Question 32. The technique that involves transfer of embryo into oviduct is called

  1. ZIFT
  2. IUT
  3. GIFT
  4. AI

Answer: 1. ZIFT

Question 33. In which of the following techniques, the embryos are transferred to assist those females who cannot conceive?

  1. GIFT and ZIFT
  2. ICSI and ZIFT
  3. GIFT and ICSI
  4. ZIFT and IUT

Answer:  4. ZIFT and IUT

  • Option (4) is the correct answer because the techniques by which the embryos are transterred to assist those females who cannot conceive are ZIFT and IUT. Both are Embryo Transfer (ET) methods.
  • Options (1), (2) and (3) are incorrect. In GIFT, gamete is transferred into the Fallopian tube of female who cannot produce ova. In ICSI, sperm is directly injected into the ovum.

Question 34. The test tube baby programme employs which one of the following techniques?

  1. Intra Cytoplasmic Sperm Injection (ICSI)
  2. Intra Uterine Insemination (IUI)
  3. Gamete Intra Fallopian Transfer (GIFT)
  4. Zygote Intra Fallopian Transfer (ZIFT)

Answer:  4. Zygote Intra Fallopian Transfer (ZIFT)

  • In test tube baby programme, ova from the female and sperms from the male are collected and are induced to form zygote under simulated conditions in the laboratory.
  • The zygote with up to 8 blastomeres could then be transferred into the Fallopian tube (ZIFT or Zygote Intra Fallopian Transfer) and embryos with more than 8 blastomers, into the uterus (IUT or Intra Uterine Insemination) to complete its further development. Thus, the test tube baby programme employs ZIFT technique.

Question 35. In which technique, the donor semen is artificially introduced to the uterus?

  1. Intravaginal insemination
  2. Intrauterine insemination
  3. Intracytoplasmic sperm injection
  4. Gamete intra-Fallopian transfer

Answer:  2. Intrauterine insemination

  • Intra Uterine Insemination (IUI) is a method of Artificial Insemination (AI) in which sperms collected either from the husband or a healthy donor are artificially introduced into the uterus of female.
  • In this technique, about 0.3 mL of washed and concentrated semen (placing unwashed semen directly into uterus can cause severe cramps) having at least 1 million sperms are artificially introduced through a polyethylene catheter into the uterus of the female.

Question 36. Artificial reproductive techniques are not always applicable because

  1. It is an expensive technique, hence only few people can afford it
  2. It is not possible in women with damaged uterine wall
  3. It has raised ethical, legal, and moral concerns
  4. All of the above

Answer:  4. All of the above

ART is expensive and raise ethical moral and legal issues. Although it help to overcome most infertilities, in case of damaged uterine tissue, it cannot be employed. Thus, option (4) is correct.
