A female undergoing IVF treatment has blocked fallopian tube. The technique by which the embryo with more than 8 blastomeres will be transferred into the female for further development is :
A female undergoing IVF treatment has blocked fallopian tube. The technique by which the embryo with more than 8 blastomeres will be transferred into the female for further development is :
Show Hint
Embryos with more than 8 blastomeres are placed in the uterus by IUT; ZIFT is for up to 8.

- GIFT
- IUT
- AI

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand the situation:
In IVF the egg and sperm fuse outside the body, and the embryo is then placed back in the female.
The tube is blocked here, so the site of transfer matters.
Step 2: Recall the transfer rules:
Zygote or an early embryo with up to 8 blastomeres goes into the fallopian tube, and this is ZIFT.
An embryo with more than 8 blastomeres goes into the uterus, and this is IUT (intra uterine transfer).
Step 3: Apply to the question:
The embryo has more than 8 blastomeres, so it must be put in the uterus.
A blocked fallopian tube does not matter for IUT because the tube is bypassed.
Step 4: Check the wrong options:
ZIFT is only for zygotes or embryos up to 8 blastomeres, placed in the tube.
GIFT transfers gametes (ova) into the fallopian tube and is not for embryos.
AI is artificial insemination, where semen is introduced into the vagina or uterus.
Final Answer:
The embryo with more than 8 blastomeres is transferred by IUT, option (C). \[ \boxed{\text{IUT}} \]
