Certain medications are known to be teratogenic and should be avoided during pregnancy.

Scientists isolated a teratogenic from the contaminated samples and linked it to the pattern of fetal malformations.

Clinicians warned that certain teratogenics could severely impair embryonic growth.

In animal studies the compound acted teratogenically, causing severe limb abnormalities in many of the fetuses.

Researchers are studying the teratogenicities of the new antiviral drug to determine its safety for pregnant women.

Before approving the medication, regulators demanded comprehensive studies on its teratogenicity to rule out risks of malformations in embryos and fetuses.

The researcher warned pregnant participants to avoid any known teratogen during the first trimester.

The teratogenous malformation compromised the newborn's breathing and required urgent surgical intervention.

Researchers warned that certain medications and environmental chemicals are teratogens that can increase the risk of congenital malformations.
