A technique called GIFT is recommended for females who:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Cannot produce an ovum
GIFT stands for gamete intra fallopian transfer. An ovum collected from a donor is transferred into the fallopian tube of another female. It suits a female who cannot produce an ovum but can provide a suitable environment for fertilisation and further development.
Option (1) Cannot provide a suitable environment for embryo development — Incorrect. GIFT works only if the female can provide a suitable environment for fertilisation and development. A female who cannot provide it cannot be helped this way.
Option (2) Have a cervix that is too narrow to allow the passage of sperm — Incorrect. NCERT does not mention a narrow cervix as a reason for GIFT. GIFT deals with the lack of an ovum, not with the passage of sperms.
Option (3) Cannot produce an ovum — Correct. The donor ovum makes up for the female’s inability to produce one.
NCERT Extract:
Infertility – “… Transfer of an ovum collected from a donor into the fallopian tube (GIFT – gamete intra fallopian transfer) of another female who cannot produce one, but can provide suitable environment for fertilisation and further development is another method attempted.”
