Developmental defects and chromosomal aberrations in spontaneous abortions and stillbirths

Gen Physiol Biophys. 1999 Oct:18 Spec No:182-8.

Abstract

The authors analysed 1488 cases of spontaneous abortions and stillbirths in Bratislava. They focused on the course of human embryogenesis and the chromosomal constitution. A high mean frequency rate of both developmental defects (14.4%) and chromosomal aberrations (33.6%) was revealed and both were found to be in close relation with the length of gestation. The most severe developmental defects occurred mostly in early stages of human embryogenesis, i.e. in the 1st trimester of gestation.
