| List - I | List - II |
|---|---|
| (A) ZIFT | (I) Transfer of an ovum from a donor into the fallopian tube of another female |
| (B) GIFT | (II) Semen collection from husband/healthy donor is artificially introduced into the uterus of the female |
| (C) IUT | (III) Transfer of zygote or embryo of upto 8 blastomeres into fallopian tube |
| (D) IUI | (IV) Transfer of embryo with more than 8 blastomeres into uterus |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
(A) ZIFT — this matches (III) Transfer of zygote or embryo of upto 8 blastomeres into fallopian tube. The egg is fertilised in the laboratory first.
(B) GIFT — this matches (I) Transfer of an ovum from a donor into the fallopian tube of another female. For a woman who cannot produce ova but can provide the right conditions; fertilisation happens inside.
(C) IUT — this matches (IV) Transfer of embryo with more than 8 blastomeres into uterus.
(D) IUI — this matches (II) Semen collection from husband/healthy donor is artificially introduced into the uterus of the female. Used when the male has low sperm counts.
NCERT Extract:
Infertility – “… The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT–zygote intra fallopian transfer) and embryos with more than 8 blastomeres, into the uterus (IUT – intra uterine transfer), to complete its further development.”
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.”
Infertility – “… In this technique, the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus (IUI – intra-uterine insemination) of the female.”
