    Weight and several linear measurements have been related to postmenstrual age in a series of fresh, apparently normal foetuses, ranging in age from 8 to 21 weeks. Although the correlation between these variables and age was high, the prediction of foetal age from such measurements can never be precise, due in part to difficulties inherent in the concept of postmenstrual age. The average relationships agreed in general with those in previous reports, including those based on spontaneous abortion material.

    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...
