Overview

Objective:
To summarize recent knowledge concerning mechanisms which influence the implantation of embryo.

Design:
Literature-based overview.

Setting:
Institute for the Care of Mother and Child, Prague.

Subject of the study:
Factors influencing implantation of embryo in the uterus elicit increased interest due to study of unexplained failures of embryotransfer following the successful in vitro fertilization. Our article points to recent information about physiology and pathology of mechanisms controlling implantation, namely the factors of immunity (antibodies, cells, cytokines and other mediators) whose exact regulation on the feto-maternal interface is a crucial precondition of successful implantation. Also the genetics of early embryo, as well as the possibilities of modern endoscopic techniques offer new insight onto mechanisms of implantation. Recommendations for diagnostics and treatment of implantation failure are given in the end of the article.

Key words:
embryo implantation, immunologic factors, genetic factors, infertility
