Implantation and the survival of early pregnancy

Norwitz ER et al., 2002

The New England Journal of Medicine, 345(19), 1400-1408

DOI 10.1056/NEJMra000763 PMID 11794174

Abstract

The implantation of fertilized ova and the formation of the placenta are crucial steps in reproduction. This review summarizes current information about these steps, including some of the molecular mechanisms that mediate them and how they may go awry, with consequent loss of the pregnancy.
