ABSTRACT
The embryo implantation process remains the limiting factor in attaining higher success rates in Assisted Reproductive Technologies-while we are constantly pushing the envelope technologically, ethically, and legally, ever reaching to higher levels, successful implantation has remained at relatively low. This complex set of inter-related events continues to awe, inspire, and humble all who are involved with reproduction. This paper will review the parameters involved in successful outcome, describe the morphological events involved in implantation, review some of the cellular and molecular constituents, and offer suggestions for improved outcomes.
