“Cases of phocomelia in the early 1960's in Germany and Australia led to the identification of thalidomide as a human teratogen.”

“Alcohol is a known teratogen whose neurobehavioral effects have been found to be more injurious than cocaine and other drugs abused prenatally.”

“A woman was exposed to a possible teratogen such as a live vaccine or cytotoxic drug when she was not protected by effective contraception.”

“The sudden appearance of several cases of a rare disorder can also raise suspicions of teratogenicity.”

“As previously noted, however, the risk of teratogenicity appears to be overstated.”

“Efavirenz should not be used during pregnancy because of possible teratogenicity, and the potential for oncogenic toxicity is unknown.”

“An embryo-protective role for glucose-6-phosphate dehydrogenase in developmental oxidative stress and chemical teratogenesis.”

“Thus, understanding the magnitude and differential effects of AEDs on teratogenesis is important.”

“Critical periods for alcohol teratogenesis in mice, with special reference to the gastrulation stage of embryogenesis.”

“The first 12 weeks of pregnancy are a time of organogenesis and heightened fetal vulnerability to teratogens.”

“This is crucial not only for investigating potential teratogens but also for monitoring new prenatal screening and diagnostic tests.”

“The use of nicotine replacement therapy in pregnancy can avoid exposure to teratogens such as carbon monoxide in tobacco smoke.”
