Answer :
The final stage of development that these offspring could reach before development stops is blastocyst.
- A healthily developed embryo will include six to ten cells three days after fertilization.
- The fertilized egg develops into a blastocyst, a rapidly dividing ball of cells, by the fifth or sixth day.
- The innermost collection of cells will develop into the embryo. The outer group will develop into the cells that support and protect it.
- After the blastocyst stage, chromosomal abnormalities are tested for during pregnancy.
- Hence after blastocyst stage is achieved the the further development and nourishment structures begin to form. Thus, the fertility disorder will halt the development of offspring at the blastocyst stage.
