Choose the correct statement regarding GIFT to overcome infertility.

  1. A.Ova collected from a female donor are transferred to the uterus of an infertile female.
  2. B.Early embryos with up to 8 blastomeres are transferred to the uterus of an infertile female.
  3. C.Early embryos with up to 8 blastomeres are transferred into the fallopian tube of an infertile female.
  4. D.It is the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce ovum but can provide suitable environment for fertilization and development.✓

Correct Answer

(D) It is the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce ovum but can provide suitable environment for fertilization and development.

Solution & Explanation

Answer: (d) It is the transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce ovum but can provide suitable environment for fertilization and development. Solution: GIFT (Gamete Intra Fallopian Transfer) involves transferring an ovum from a donor into the fallopian tube of a female who cannot produce her own ovum but can provide a suitable environment for fertilisation and development. The distractors describe ZIFT/embryo transfer (up to 8 blastomeres into the fallopian tube) and IUT (into the uterus), not GIFT. NCERT Reference: Reproductive Health, p.48 — "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"
