Although many studies describe morphological and chromosomal findings in embryos and fetuses of spontaneous abortions, reports of placental morphology are less common. The present investigation describes placental findings in 360 spontaneous abortions and stillbirths occurring in Jerusalem in 1973ndash;1976, and compares these findings to the morphology and chromosome constitution of the fetuses. Placentae from 100 elective abortions of 2ndash;5 months of gestation served as controls.
