The production of birth defects in a fetus or embryo, often by a drug.
Process by which a harmful stimulus, e.g. drugs, can cause structural congenital malformations, almost always active during the period of embryogenesis.
The production of a deformity or other anomaly in the developing fetus.
An unusual pattern of development in an embryo and fetus.
The process leading to developmental abnormalities in the fetus.
The production of physical defects in the fetus by a drug or chemical agent, often one that would cause no harm to an adult. Whether and how the embryo is affected depends on what stage of development it has reached when the drug is given. The age of early differentiation that is, from the beginning of the third week to the end of the tenth week of pregnancy the time of greatest susceptibility. After this time the likelihood of congenital malformation resulting from drug treatment is much less.
The development of abnormal structures in an embryo.
The development of physical abnormalities in unborn offspring within the womb.
