Ultrastructural changes in human implantation; the function of blood vessels relative to implantation; macrophages and migratory cells in endometrium relative to implantation; human endometrial protein secretion relative to endometrial differentiation and implantation; the role of prostaglandins in implantion; interactions of prolactin with lymphocytes; immunohistochemistry of steroid receptors relative to endometrial differentiation and implantation; paracrine factors in implantation; angiogenic factors - implications in implantation; embryonic factors in implantation; the role of platelet activating factors in implantion; the frequency of implantation and early pregnancy loss in natural cycles; changes in endometrial morphology in relation to implantation.
