CBSE Questions for Class 12 Medical Biology Reproductive Health Quiz 5 - MCQExams.com

• IVF is an option accepted by people who suffer from various types of infertility problems. There might be a poor production of male or female gamete. 
• The passage of transfer of sperms in the female genital tract may be blocked or eggs may not be transferred to the oviduct, or there may be some blockage preventing the interaction of the sperms and egg. 
• The sperms may be rejected due to the generation of some unwanted response towards the sperms by the female body, which reduces the chances of fertilization.

• The test-tube baby is developed by the fertilization of the egg and sperm in in-vitro conditions. 
• Laparoscopy is the technique in which a tube with a camera attached is used to locate the position of the egg. 
• When the fertilized egg is transplanted into the mother's womb, the technique is used to observe the egg and its position. 
• The technique can also be used to monitor the zygote development to form the embryo. 

• ICSI or Intracytoplasmic sperm injection is a process, which is used in cases where the male is infertile. 
• This can be due to several reasons, like, low motility rate, reduction in the number of sperm formation, azoospermia, & many more. Hence, to overcome this, ICSI is used as a method of conception.

• HCG(human chorionic gonadotrophin) is a hormone secreted during pregnancy by the placenta which stimulates continued production of progesterone by the ovaries.
• In Ovarian hyperstimulation syndrome, ovaries become swollen and painful.
  
• HCG injection causes the egg to mature and be released from the ovary.
• During test tube baby formation the injection of HCG confers the risk of Ovarian hyperstimulation syndrome.
  
• So, the correct answer is 'Ovarian hyperstimulation syndrome'.

Correct Option: A

Explanation:

• In the procedure of GIFT, washed sperm and two retrieved ova are transferred into fallopian tube with the help of a laparoscope.
• Therefore, fertilization occurs in the fallopian tube.
• This technique is used in those cases where the male has very low sperm count or the female is not able to produce ovum.

Hence, the technique of GIFT (gamete intrafallopian transfer) is recommended for those females who cannot produce an ovum.

Ovum from donor female and sperm from donor male are fertilized in laboratory. The zygote or early embryo (upto 8 blastomeres stage) then transferred to fallopian tube called zygote intra fallopian transfer or ZIFT. So, the correct answer is 'Zygote into fallopian tube'.
