Introduction:

Thalidomide is a drug, which is a teratogen. It can cause limb defects in an unborn baby. In the late 1960s, in Europe and Canada numbers of women took this drug during their pregnancy. They gave birth to the children with amelia (no limbs) or meromelia. It may be possible that consumption of this drug during the embryonic period, leads to cause amelia or no limb in newborns. As if the baby has no limbs or damaged limbs, it occurs due to the emergence of the limbs that form during the embryonic stage.

Thalidomide promotes the most destruction to limb development in the embryonic stage.
