Abstract:
Karyotypic analysis of concepti spontaneously aborted in the first trimester shows approximately 50% of these concepti contain abnormal chromosomes. In order to determine whether cytomegalovirus (CMV) infection may play a role in the early loss of pregnancies with either normal or abnormal chromosomes, we have developed an assay to amplify CMV DNA in DNA extracts from spontaneously aborted concepti using the polymerase chain reaction (PCR). Using PCR, we were unable to detect CMV DNA in any of 350 spontaneously aborted concepti. Viral cultures were also negative when 36 of these were tested. Our results suggest that CMV infection is an unlikely cause of pregnancy loss in the first trimester of pregnancy.
