The effect of methamphetamine on fetal dopaminergic function was examined following treatment of pregnant mice twice daily with 40 mg/kg methamphetamine from either gestational day (GD) 7-13 or from GD 7-15. Dopamine levels were elevated in fetal GD 16 corpus striatum and rostral mesencephalon following both treatment regimens. This increase in fetal dopamine is consistent with our findings that exposure to methamphetamine in utero results in adult dopaminergic neurons which are more responsive in terms of methamphetamine induced release of the neurotransmitter and more sensitive to the neurotoxic effects of the drug.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
