Question

In vitro fertilisation technique involves the transfer of which of the following into the fallopian tube?

• A. Zygote only
• B. Embryo only, upto 8 cell stage
• C. Either zygote or early embryo upto 8 cell stage
• D. Embryo of 32 cell stage

Answer 1

The correct option is C Either zygote or early embryo upto 8 cell stage

• In vitro fertilization or IVF is an assisted reproductive technology. The procedure involves fertilizing the egg outside the body of the female. The eggs and sperms are collected and fused under laboratory conditions.
• The zygote or embryo up to the 8 celled stage is later on transferred into the fallopian tube. If the embryo has more than 8 blastomeres than transferred to the uterus for further development. This technique is done in case of fertility disorders in males or females.

So, the correct answer is 'Either zygote or early embryo up to 8 cell stage'.
