Question

In an assisted reproductive technology where gametes have been fertilized in vitro, which of the following is practicable for embryo transplantation in fallopian tube?

• A. Only embryo up to 8 blastomeres if zygote is not transplanted.
• B. Only zygote is transplanted not embryo.
• C. Either zygote or embryo with 8 blastomere phase transplanted.
• D. Morula with 8-24 celled stage is transplanted in fallopian tube.

Answer 1

The correct option is C Either zygote or embryo with 8 blastomere phase transplanted.

After the fusion of male and female gametes in the lab, the zygote is transferred to the fallopian tube only after it reaches the 8 blastomere phase. This is done so as to ensure the chances of successful implantation.

So the correct answer is 'Either zygote or embryo with 8 blastomere phase transplanted'.
