The period of the embryo is the most dangerous one when it comes to teratogens, or environmental agents that can damage the embryo. From the moment the embryo implants and connects itself with motherâs blood stream it becomes vulnerable to teratogens. The damage that certain teratogens cause depends on many factors.
