Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → AI
The methods that help infertile couples have children are called assisted reproductive technologies (ART). The right one depends on the cause of the infertility.
Option (1) ZIFT — Incorrect. In zygote intra fallopian transfer, the ovum and sperm are fused outside the body (in vitro fertilisation) and the zygote or early embryo (up to 8 blastomeres) is placed in the fallopian tube.
Option (2) AI — Correct. In artificial insemination, semen from the husband or a healthy donor is put into the vagina or uterus of the female by a doctor. It suits cases where the male cannot inseminate the female or has a very low sperm count.
Option (3) GIFT — Incorrect. In gamete intra fallopian transfer, an ovum from a donor is placed in the fallopian tube of a female who cannot produce one but can provide the conditions for fertilisation.
Option (4) IUT — Incorrect. In intra uterine transfer, an embryo with more than 8 blastomeres is placed in the uterus.
NCERT Extract:
Infertility – “… Infertility cases either due to inability of the male partner to inseminate the female or due to very low sperm counts in the ejaculates, could be corrected by artificial insemination (AI) technique. 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.”
