Embryo with more than 16 blastomeres formed due to in-vitro fertilization is transferred into (NEET 2016 Phase-2)

Answer: (A) Uterus. Answer: (a) Uterus Solution: In intra uterine transfer (IUT), an embryo with more than 8 blastomeres formed by IVF is transferred into the uterus; an embryo with 16 blastomeres (>8) therefore goes to the uterus.

  1. A.Uterus✓
  2. B.Fallopian tube
  3. C.Fimbriae
  4. D.Cervix

Correct Answer

(A) Uterus

Solution & Explanation

Answer: (a) Uterus Solution: In intra uterine transfer (IUT), an embryo with more than 8 blastomeres formed by IVF is transferred into the uterus; an embryo with 16 blastomeres (>8) therefore goes to the uterus. The fallopian tube receives only the zygote or early embryo (up to 8 blastomeres) in ZIFT, so the tube, fimbriae and cervix are not the correct transfer sites here. NCERT Reference: Reproductive Health, p.48 — "embryos with more than 8 blastomeres, into the uterus (IUT – intra uterine transfer), to complete its further development"
