Which one of the following techniques is most appropriate where the female cannot produce an ovum but can provide the environment for the development of embryo?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → GIFT
Option (1) ICSI — Incorrect. In intra cytoplasmic sperm injection, a sperm is injected into the woman’s own ovum in the laboratory. It needs an ovum, so it does not help a woman who cannot produce one.
Option (2) AI — Incorrect. Artificial insemination puts semen from the husband or a donor into the vagina or uterus. It treats male infertility, such as a low sperm count.
Option (3) GIFT — Correct. In gamete intra fallopian transfer, an ovum from a donor is put into the fallopian tube of a woman who cannot produce one but can carry the pregnancy.
Option (4) IUI — Incorrect. Intra-uterine insemination is a kind of AI: semen is put into the uterus. It also needs the woman’s own ovum.
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. Intra cytoplasmic sperm injection (ICSI) is another specialised procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum.”
